Lol... german engineering. I think mass production and quality contol is more a problem. In relation of (canyon) carbon bikes/parts out there the number of fails is very low. In general i have see broken carbon parts from every brand...
I can confirm that 2022 Ultimate comes with the "reinforcement element" already in place...I was aware of the issue in the past so I double checked before ordering and I would say that tech support was quite honest in saying that the problem was indeed real without this element in place..anyway, thanks for the video! better spreading this type of information than keeping it inside forums
@@fede1275 the issue with Canyon is a bit resumed with this problem you had...in order to avoid any mishap with a "non-physical" customer service, before buying, I've been lurking forums and blogs for about 8/10 months to discover all the little problems/issues customers had and how they were fixed..you really need to be an informed buyer as the tech support is reliable only at times..the first guy I spoke to had no clue/answer to my inquiries on the subject of the fork-tube cracks, a few days later another one was totally aware of the issue, was really detailed in the explanation and confirmed that the solution was integrated in all new models
I run the PRO headset expansion nut 1-1/4'' 50mm in my canyon ultimate with the H31 cockpit for peace of mind. It is disappointing that Canyon don't supply their bikes installed with an expansion plug to reinforce the fork steerer against the clamping forces (as it is done by most manufacturers). It may works in their computer analysis, but if you consider the manufacturing tolerances and user error (overtightening the fork steerer) this should have been included for additional safety. After all it is in their best interest to avoid disputes with customers, etc.
@@fede1275 I don't think it can be considered as a good solution, I would still prefer a long expander plug like the one from PRO for 1" 1/4 steerer tubes. The problem with the insert provided by Canyon is that its outer diameter does not match exactly the inner diameter of the steerer tube. This means that the steerer tube, because of the clamping force coming from the handlebar, will still flex until it makes contact with the metal insert. Is that deformation concerning? It depends, but for sure it's a deformation that still happens in an asymmetric manner (because it's not radial clamping). Measure the ID of the steerer tube and the OD of the metal insert...my guess is that there is more than 0.1 mm of difference in their diameters. With an expander plug, the difference is zero, which is what you want ideally.
hey does the screw provided with the PRO headset fit the Canyon H31 cockpit? or the other way around? I might have damaged the fork a tiny tiny bit and want to run that setup to be safe
Excellent video for me. I’m about to add a VeloBike 18mm extension / 50mm compression plug to my new ultimate. Thanks for taking the time to create and share your experience.
Sadly most people do not notice these things either because they do never disassemble their bike or because even when disassembled, they can't notice the notches on the carbon. My roadlite 6 had the same problem. When I removed the stem to change orientation by flipping it to get the riding position a bit less aggressive, I also noticed the existence of no compression plug. And of curse when I remove the stem I noticed the carbon was compressed and notched right along the edge of the stem clamping edges. Since I also had a bent derailleur (but I have the straightening tool), I decided to fix it all myself instead of contacting them. I went to lathe shop and created a cylindrical element much wider than the reinforcement piece you showed in the video and of height from the top of the tube all the way towards that compression-plug wannabe they placed inside the fork. I've been riding my bike with this almost three months now, no problems. I'm really disappointed by Canyon. The only reason I would ever return as a buyer again would be due to their prices. Obviously the crew that assembles the bikes is mediocre at best. As for the engineering team, what can one say of an engineering team that uses no compression plugs in forks? Every single bike manufacturer uses one, they cost almost nothing, they barely add any weight to the bike and they provide great protection for the top of the fork tube.
Yes, I believe they relied on the stronger oversized steerer tube and did not add a compression plug. With round clamping stems maybe the problem is not so big, but when the stem/bar have the rear pushing clamping plate, the forces are driven in a narrow point that can cause the damage. In fairness when I smashed a section of 1 1/4 and 1 1/8 steerers, the oversized one was noticeably harder to break, so maybe it would not cause a full failure, but still not ideal.
My late 2021 Ultimate have the wedge from the factory. But thanks for making this video so I could check my bike before something would go wrong. Remember to add some clear nail polish to the carbon ends after you cut it. This will avoid water or sweat entering and doing damage over time.
Like I already commented on your photo yesterday, the same thing happened on my Canyon Endurace but with the standard stem. The problem was (according to the bike mechanic that was subcontracted by Canyon to look at the issue), that there was no spacer on top. I really don't think that this comes from overtightening. I'm glad that you bring more attention to this problem, I only noticed it during maintenance and this can become really dangerous.
Same here with the same model. I also asked canyon to send me the reinforcement element that Federico talks about, but they refused. I am really afraid that it will happen again
Same thing is happening with me. Standard stem on an Endurance. It's cracked right where the stem bolts clamp. I have only ever used the torque wrench that they sent with it. I have it set up the same way it came with no spacers above the stem. Canyon insisted that I overtightened it and will only sell me a fork under their crash replacement program. $325 plus taxes and shipping.
They claim on their website that it is a 'compression plug', with those exact words. But its so measly that I almost don't know why they bothered. Is this to save weight or something. I almost bought a canyon and at the time it just didn't look right to me. I was going to purchase the 50mm deep plug from pro. Not many brands make a plug for the 1 1/4 oversized steerer. Look at the replacement compression plug that specialized now ships on the tarmac after the voluntary recall. It's massive, something like 70mm deep (as it should be).
On all FIVE of my Canyon's I removed that plug and soft top cap and replaced them with the Pro 50mm expander and top cap.... also Canyon headset bearings and really badly greased from the factory and tend to rust within the first few months. Again, changed them and greased them with no problems.
Well explained Fede , I have to admit I’ve been a bit sceptical about canyon bikes & their issues. Especially the bar issues etc. But I guess on a good note their customer service has been top marks . Good luck with the cutting of the fork !!!
Very informative and well explained video for canyon users. You are lucky for noticing it before anything bad happens and you have a youtube channel as canyon do not provide free forks or even simple spacers for everyone who has the same problem. One of my friends with the same one piece h31 handlebar had to pay for the new fork. I have an ultimate with the h36 with a different bolting pattern so I did not have the same problem however as an engineer I always used a spacer above the stem for the reasons you explanied. An other problem which I had was failure of the fixing spacer at the bottom with a bolt on it. This is a very fragile plastic part which eventually fails by cracking even if you torque it less than 2 nm as stated. I had to pay for the whole spacer set as canyon was not helpful again.
I can genuinely say that Canyon have always been supportive when I needed them, even before I had the channel. This is my first major issue though. I have been reading different interactions and it's difficult to judge from the outside. I definitely believe they should add the ring to the H31 spacer kit, as a potential upgrader will fit it on a bike with the V13 stem that do not come with it.
This was a great video and demonstrated the exact issue I am now dealing with on my Endurace CF SLX with the integrated head set. Thanks for the great info and the humor sharing the details.
Very well detailed and nice to see Canyon have responded to yourself and addressed the issue. I do think it would be better if they fitted an expansion bung as standard though. It sounds like an 1" 1/4 bung will be difficult to source.
Federico, once again you are reading my mind! I was literally just researching the H31 ergocockpit and very much planning to upgrade to it. However, with that clamping mechanism, I may well reconsider. I do love those swept-back tops though!
@@davidmoore4661 the reinforcement ring is fitted as standard on new bikes with H31 or CP10 cockpit, not sure if also on H36. The spacers kit does not come with one, only with a replacement expander element for the top cap.
Federico. cracking video very well explained what happens in that area. had issue with new Ribble bike delivered last summer. play in headset couldn't tighten up. I ended up over tightening the bolt at top of steerer and sheared it Total panic. luckily managed to sort it. just didn't realise importance of all that stuff. my new bike has fully integrated bar stem and mentions about steerer BUNG so will be taking extra care this time. with help of your video. 👍👍👍 many thanks
Fede. Excellent video. Every Canyon rider needs to understand these issues. Well presented. My only issue is that with every bike part black they were getting lost amongst your black jersey background. Perhaps a lighter grey or a more colourful jersey for future appropriate videos. The man in black needs to be in colour sometime !!
I had this same issue with a Grizl and a standard clamping stem. No offer from Canyon to replace the fork. I had to buy it. I'd like to fit the reinforcement sleeve with the new fork, but I doubt the top cap will fit. BTW, I believe (but could be wrong) that the protruding part of the top cap is supposed to be inserted down into the steerer slightly giving it some reinforcement. This means that you have to make sure not to allow too much height difference between the top of the steerer and the top of the stem. Seems to me that they have to be nearly flush. This would be extremely easy for Canyon to fix simply by making the protruding part of the top cap longer by several millimeters.
Yes, even if the standard clamping stem should be safer, I heard of some instances like yours. With the reinforcement sleeve you will not be able to use the original top cap, I bought a flat carbon one that clears the ring. The top part of the ring is slim enough not to interfere with the top of the stem. You can also fit a small spacer on top to compensate if needed.
@@LuiS-kj1qe as I mentioned in the video Canyon supplied the fork as they acknowledged the issue. I believe a brand new fork list price is around £490.
Aloha from Maui, I have the 2021 Endurace with standard stem like your original setup exactly. It came with a 5mm spacer on top but I put a 10 and that 5 to make 15mm on top right off the bat. The so called plug is right around the top bolt on the stem I feel safe about it I was going to put a real plug but just held off. If I ever cut it I will always have a 5mm spacer on top, I am strongly against no spacer on top because the stem is only 97% on the steer tube with the couple mm you need to clamp it down together. Your new bar set up may have to run no spacer on top but if you could I would but that new insert they gave you might fix everything I'd get one but my stem would be below it and most likely I won't cut it for resale. So far no problems with my steer tube after 3500 miles and I'm your size only my seat post creaks and sounds like the BB but if I clean the post and inside every couple rides its fine the bike feels brand new still. 🤙
Great explanation. I just took off my CP10 stem to see why it was feeling a little “crunchy.” Same failure and I’m religious about using a torque wrench, especially on carbon parts, especially on my stem! We’ll see what Canyon says. My bike is a 2018 or 2019 so it’s got a lot of KMs. (Not KOMs 😅). I don’t really blame Canyon particularly. Every manufacturer has similar issues occasionally.
Hi @matthewhughes5472! Did you already hear back from Canyon? Unfortunately the same thing happened to me as well... Canyon offered to send me a new fork, but they charge almost a third of what I paid for the whole bike (Ultimate CF SL 7 Disc)! Now I'm wondering whether I can massively reduce the stack on the bike and cut the cracked part of the steerer tube instead. Curious to hear how things are going at your end! Cheers
@@smann7992 yikes! No, I’m still waiting to see if they have an extra fork around. Were you the original owner of the bike? I’ll let you know if they quote me a price.
@@smann7992 Canyon found me a fork within 24hrs. Not a matching color, but it’s black so I’m happy. I have to pay $499 up front, but they will refund it to me once my old fork is removed and destroyed (or more destroyed). It should arrive in a few days. I’m the original owner of the bike, and it’s a 2019. I’m very pleased with the outcome. Great customer service.
@@mattthehoople Thanks a lot for the update -- that sounds like an excellent solution. Unfortunately, even though I'm the original owner of my bike, it's too old to fall under warranty (I bought it new in 2017), so I'll have to pay the full price... Might do it anyways, though, as the bike seems pretty useless otherwise. Good luck with the installation of your new fork and happy riding!
These engineering "after thoughts" are so unbelievable. It's mind boggling that they believe a hollow steerer can with stand compression forces. Jeez. Be safe out there doc 🚲
@@fede1275 it seems to me that the steerer plug is only slightly better. Every component must be checked and rechecked constantly 🙄 London roads with the potholes are also are part of the problem. Grrr
I have endurace. By canyon maintanance book they propose you have to change fork every six years. When I contacted them that I want to by new fork they said we do not sell forks after waranty period. At that time I could not buy any where 1 1/4 flat fork. Most forks are 1 1/8. Very bad experiance with them. Original compression plug died so I took Pro one. With my fork everything is ok, bit if you want to buy fork from them they do not sell. When I said them that I will put the info on web they offer me 40 Euro gift card. When I refuse it they offer new fork for 280 euro. Frederrico, did you buy fork or it was free?
Good that you found this out before it failed on a ride. Canyon have some odd design theories - never understood their steerer/stem arrangements including that weird allen keyed adjuster (do they still sell that?). I ride Giant and my TCR has an oversize steerer too, with a stem plug - nuff said! Cutting a steerer is very easy with a clamp/guide and a suitable hacksaw blade (total outlay < 20quid). Just measure 15 times before cutting!
Indeed! They don't use the allen key adjustment anymore, the steerer is more conventional apart from the missing compression plug. I guess mine was an odd combination as I upgraded the bar/stem later on, but maybe the ring should be supplied.
Thanks for that important information. I can confirm that the issue is also on the round stem. My cracked likes yours. I tighten the bolts with torque wrench only, canyon is blaming my fault. It´s the same words as your answer.. **** Canyon, that´s bullshit. First and last bike of this brand.
Thanks for your detailed and clear video👨🎓! Canyon was generous to give you a new fork; they could blame the damage of the steerer to the mechanic who installed the integrated cockpit...
Thx. I had the same Problem wirh my grail cf and find also see this as the root cause. I also get a new fork but without the part you show. I ask them now why they just send the fork and not the preventio. When i don‘t get the part from canyon (5€?) i will glue a stainless steel pipe in there
I am worried that my steerer is damaged and don’t really know what to do, because I feel insecure riding my bike now. I hope maybe you can help me to determine what I should do. I was at a bikefit and apparently my stem has to be set way lower than it is by default. So I took out some spacers and because of the pin-system, they couldn’t be placed above the stem, so I left the part of the steerer above the stem blank. I rode some time (quite hard) for a few weeks until I felt like this was a good position and looked up the manual because I wanted to gather information regarding the whole build up, for finally shortening the fork steerer. I discovered, that the manufacturer explicitly states to NOT leave space above the stem (even with spacers) because it damages the steerer tube. (Most likely because the compression device isn’t long enough to work against the stem pressure there.) Also I red a lot of things on the net from bike manufacturers explaining how sensitive those carbon steerers are to pressure. And now I am feeling unsafe riding my bike, even though there are no visible errors, but I also read carbon doesn’t tend to show signs of damage. I would change the fork ASAP, but apparently, there are no forks with 1 1/4 to 1 1/2 anymore, at least not in my region or online. Shouldn’t I be so worried? I mean are all those saying from bike companies and mechanics made up? please help :( I wanna ride again but I am very confused.
Thank you for the confidence in my judgement, I need to remind you that I'm not a carbon expert. Having said that, did you notice stress fractures on your steerer? Are you just assuming your steerer is damaged? If you are worried have it checked, but if it looks fine it probably is. What stem are you using? Do you have a reinforcement ring in your set up?
I had the same steerer failure. The internal of the steerer didn't show crack but where the external meets the clamping wedge had a dent. Canyon Ultimate CF SL 8.0 rim brake 2019 model with CP10 handlebar. The compression plug is in the middle of the steerer, not in the clamping area. That's a strange/stupid design. I emailed Canyon when I found out about the problem last year in September and had some debate about whether it was a user error with the wrong torque or a design defect, they finally agreed to send me a new fork but there was no stock at the time. Last week they finally shipped the fork. In the meantime, What I did is cut the damaged part of the steerer and put a regular Giant OD2 stem tilting upward to compensate for the loss of height.
This is because the plug inside Canyon forks is not designed to compensate for the clamping forces, but only to pull up the fork and compress the bearings. It seems that they introduced the ring in 2021 as both CP10 and H31 have the same clamp.
@@fede1275 Although I like the sleek look of integrated handlebar and the comfort of the aero/flat section to rest your hands, I'll stick to normal bar/stem combo in the future. To be honest I still think that ring is too shallow to fight against the wedge. I'm curious if you're able to use a regular expander plug instead of that ring.
Great video, i would recommend you to use a proper torque wrench instead of the plastic thing, especially on carbon. I don't trust plastic since it can wear out easily...
CF SL8, I went the other way around, swapped CP10 with V13 + round handlebar combo because I needed to shorten the stem and fit aero bars (cant fit anything on cp10). It was a nightmare to reverse engineer Canyon solution, why is this here, what is that for etc lol. Although Canyon didnt say anything about the metal sleeve reinforcement (EP 1297-01) for v13 I decided to put it anyway and watching your video, it's good that I did 😁 Thx 👍
Great video again dude! I guess this is why the H31 cockpit is half price on the Canyon shop now! Where did you get the reinforcement part for the steerer tube from, I can't see it on their website?
Thank you! Pity the discount is available only on some sizes, otherwise I might have bought another one! Canyon don't list the reinforcement part on the website, will need to ask directly.
Had exactly the same problem. At the beginning they blamed me for overtightening the stem and offered me a replacement fork for 160€ Finally they changed the fork for free. The problem is I am very nervous that this will happen again. It seems like a weird design... I appreciate their customer support but I don't know if I i would buy again.
Ciao Federico, ottimo video analisi. Ho avuto un problema simile con una canyon ultimate venduta con manubrio integrato CP10. Il meccanico dopo aver tagliato la parte in eccesso della forcella non ha inserito il “wedge insert” di rinforzo e la pressione ha danneggiato, come nel tuo case study, il tubo forcella. Per curiosità nel tuo caso canyon ti ha fornito una forcella nuova in garanzia? Grazie mille e complimenti ancora per l’analisi dettagliata.
Ciao, grazie! Si, nel mio caso sono stati molto efficienti, mi hanno prestato una forcella usata che avevano a disposizione fino a che non e' arrivata quella nuova in garanzia, per farmi usare la bici nel frattempo. Vicino Londra c'e' un centro Canyon di assistenza. Poi ho restituito quella e tenuto la nuova. So purtroppo che in altri casi non sono stati cosi' di supporto. Adesso credo che abbiano esaurito lo stock per le bici non piu' in produzione.
Canyon insists in proprietary parts with designs significantly different from the rest of the industry and that comes with its own risks. Going with standard designs means using something that has been widely evaluated and tested. on the other hand, coming with a completely new design may mean that there are cases that haven't been tested as exhaustively as they should, due either to oversight or because they simply didn't existed at the time (as was the case here). Canyon is learning this the hard way with their shifter clamp on their latest Aeroad handlebar fiasco, the issues with the Aeroad seatpost design or the case shown here.
Grazie tanti Federico! This is so timely. I just bought a brand new Endurace AL 7 as my winter bike and it indeed comes with a carbon fork/steerer. I was trying to find in the Canyon website this reinforcement plug (EP1297-01) for the 1 1/4" Canyon steerer you mentioned in the video without success. Could you provide a link to it?
Hi! I have an Endurace CF 7 with a V13 stem. I want to install the Wedge extension like you. What top cap did you use? I don't think the original from Canyon fits
Yes, Canyon top cap would not fit the reinforcement ring or a compression plug. I got a Carbon Ti X Cap for 1 1/4 steerers, but there are other flat caps available on the market for the larger steerers.
I now have two steerer fork failures on my endurace with the H31 cockpit, stem bolts tightened always using a torque wrench and to 5nm - imo they have a design issue here
Federico: Do not cut the new steerer tube in one go. Stop before cutting completely through, rotate it 180° and cut the rest. Reason: It may splinter otherwise. I had that recently, and it is a pain. And: Measure twice before cutting ;-)
Yeah damn sadly this happened to me recently… I wonder if I can put in that reinforcement ring and continue riding or do I need to get a brand new fork now if cracks already exist?
Not sure really. I have a video where I hit the steerer with a hammer and it's not easy to crack. In theory it should not collapse with a proper compression plug or metal sleeve inside, but it's not a comfortable thought thinking it is actually cracked.
@@fede1275 yeah totally hear you on that.. been trying to find replacement forks on Canyon but doesnt seem to find it? Really great videos by the way man, this one is spot on and I thank you very much for shining a light on this issue! 🙏🏼
Ahh man.. I'm back and ust got the verdict that I probably need to replace my fork but since I bought the bike second hand, Canyon refuses to sell me spare parts.. Do you know how I can find a fork that fits with this 2019 Canyon Ultimate CF SL? Hope all is well with you man and keep it up as always!@@fede1275
And the second fail of canyon !!! I received my new canyon aeroad the slx DI2 version in January 2021 and I have already sold it! less than 250 km driven !!! First had contact about the wear on the seatpost. then the broken bicycle handlebars! And when I took it to the canyon service center they discovered two cracks in the carbon of the rear uprights . got a new frame but confidence was gone hence the sale.
Hi I just got my h31 few weeks ago and did not received this small part , is it available anywhere on canyon website ? I found only one for 1 1/8 tubes Btw great videos and content 👍🏻
Thank you! The reinforcement ring is not listed as a spare part, it's fitted as standard on new bikes that come with CP10, H31 or similar rear clamp cockpits. You would need to contact Canyon directly to get it. It's called EP1297-01.
Hi. When you make a mark on the steerer tube against the top of the stem, how many mm below that line do you cut? I see that some canyon models don’t have expander plugs but rather just wedges so you don’t need to accommodate that few mm of the expander plug.
Your aim is to leave 3mm from the top of the steerer (of the compression plug if there is one) and the top of the stem, assuming that you have a flat cap, to allow for the bearing compression. If the top cap shape is domed and comes down towards the steerer you might need more space, as the steerer might hit the cap before the correct adjustment. As you mentioned most Canyon don't have the expander, but just a bung deep down to engage the top cap bolt and the top cap design should not interfere with the steerer when compressed. I used the metal reinforcement ring and I had to use a flat cap, not the original one.
Hi Federico! Thank you for the very interesting video! Do you have any idea of the internal diameter of the wedge extension part? I am considering to fix it on my Grizl steerer tube, but then the normal cap would probably not fit anymore.
Hi, I haven't measured properly the sleeve, you might want to check the internal diameter of the steerer on your bike. With the Canyon part the round cap would not fit.
One additional question, I was watching the video again and noticed that you mention using the wedge extension with a V13 stem...how did you solve the cap compatibility issue? Did you find another cap model that would work? I searched a bit but I think I might need to 3d print one myself...or 3dprint a compatible sleeve, might be easier😂
@@bogdanc2309 So I refer to the wedge as the small compression plug that sits inside the steerer tube, around 3cm in, and is needed for the top cap bolt to screw in and set the bearings preload. This does not touch the top cap. The reinforcement sleeve sits at the end of the steerer and will clash with the standard round top cap. In my V13 set up I bought a flat top cap in 1 1/4" from Race Ti, but you can find some more in the market. Being flat helps not touching the inside sleeve.
I agree with frequent checks and longer sleeves, if they fit your bike. A 5mm spacer above the stem can give a better clamping position and the steerer is not pushed where it is weaker. Bontrager also mention the need for 5mm below and above their stems. Spacers above the stem are dangerous when they then place the stem clamp outside of the intended compression sleeve. For Canyon there is no such a thing.
I dont understand why they dont fit compression plug. If they decide to make steerer bigger, they shouldve manufactured a matching compression plug. It’s been used for many many years and it’s been proven to work. I dont get why canyon decided to forgo the compression plug.
How did you remove the steerer tube "expander"? I understand that once inserted it would be wedged if pulled up. How can you relax the wedge to be able to pull it out?
It's not easy. I first released the nut inside the wedge without removing it. Then I used the bolt you usually use with the top cap to engage it and tap it lightly to get it unstuck. Then with a pair of pliers applied to the bolt I managed to remove it.
My Canyon Endurace AL 7 comes with 1 1/8" steerer fork, not the 1 1/4". Still the space between the top cap and the wedge is huge ( at least 5cm). Canyon doesn't sell a solution like the one you showed at the end of the video for 1 1/8" forks. Should I use a traditional expander plug?
I didn't know the AL 7 came with a 1 1/8" steerer, what is the stem type you have? Definitely the smaller steerer is weaker, but please double check for me the steerer size.
@@fede1275 The fork is the Canyon FK0042 CF Disc with 1 1/8" steerer tube. The stem is the standard aluminum (non-integrated) Canyon V15 with head tube diameter of 1 1/8".
@@The_One-Eyed_Undertaker with the smaller steerer a proper compression plug is needed, to reinforce where the stem clamps. I would definitely get a traditional long plug to cover that area and remove the small plug. I smashed with the hammer the two steerers in a video and 1 1/8" felt much weaker.
@@fede1275 Thanks Fede! Is there any brand /model of compression plug that you could recommend or have good experience in the past? I have replaced basic parts like tubes, tyres, chains, cassettes and gear cables in my bike and know how to bleed my brakes. But I have never done anything on my head tube yet...🙄
@@The_One-Eyed_Undertaker you will have plenty of choices in that size, but you would need to check if you have enough space between the top of the plug and the cap once installed. I prefer flat caps as it's easier to measure, you need 2-3mm free space to preload the bearings. If the top of the plug hits the bottom of the cap you would not be able to preload with enough tension.
Great video ... and nice hint - not going VEGAN yet- ;-))) I really had to laugh loudly. But i have to say. I swapped on my new Dogma F the steer plug over the standard one which came from Leon Bikes or better pinarello factory stock to an oversize Dedaelementi Plug! Just for safety reason cause i am more on the heavier side than a durianrider lean shape !
I'm surprised Canyon were so helpful considering their warranty department manager was popular a while back for rejecting a warranty request on a BB shell that was out of their stated tolerance range, maybe things or the manager have changed since... Good that they fixed it for you. At least you're not out of pocket for something they know they have done wrong, the fact they didn't ask you to pay is an admission of that IMO, but they still like to play the old trick of blaming the users overtightening bolts ofcourse, have to save face I guess.
Yes, I have to say they were very good and quick to resolve the issue. Maybe if they say that that cockpit clamp also needs the reinforcement ring they would then need to send one to all the bikes they shipped before without it. New bikes with that syle of clamp now come with the ring.
@@fede1275 essentially they are using customers for their R&D and testing and then quietly implementing changes when the field test results come back as "if someone faceplants the floor we will be liable due to engineering negligence" top company.
@@fede1275 It's taking a bit longer (already a month of back-and-forth with the customer service) to get it sorted as it is already past the 2 year warranty but I am claiming it within their "6 year Guarantee." Initially they offered a crash replacement but I pushed back and escalated the issue. After more than a month since I made the claim they finally offered the fork for free.
Did canyon replace the fork free of charge or did you have to pay? They’re offering to replace mine as a crash replacement for a discount over the normal price. But this doesn’t seem quite right.
They replaced the fork free of charge. I believe the problem from their side is that I fitted the H31 at a second stage. On new bikes with H31 or CP10 they also add the metal ring, but it is not supplied when you buy the cockpit separately. What happened to your fork and what setup you have?
@@fede1275 ultimate cf SL with a cp10. I got the cockpit from eBay wanting a change from the original. it didn’t come with the metal ring, nor did it seem the previous owner had one supplied with it.
@@edmorris5433 unfortunately it seems that stems that have a round clamp can still work well with steerer without a compression plug. H31 or CP10 with the rear push clamp do put too much stress on the steerer without additional inside support.
Salve, è quindi indispensabile montare quell’accessorio sulla forcella? Ho ordinato un cockpit H31 non sapendo di questo problema, ora ho chiesto delucidazioni a Canyon!
Si, anche io ho preso l'H31 come upgrade e nel kit con gli spacers non c'e' in reinforcement ring. Canyon con gli stem tradizionali non usa nessun rinforzo per la forcella: in questo caso lo stem classico ha le viti al lato ed il carico e' radiale e meglio distribuito. Con l'H31 le viti sono dietro e il carico e' diretto solo sul retro dello steerer. Canyon su tutte le nuove bici con H31 o cockpit simili con le viti dietro monta il reinforcement ring per supportare la spinta dell'attacco. Secondo me dovrebbero includerlo se si acquista il cockpit separato.
@@fede1275 grazie per la risposta! Mi hanno appena comunicato da Canyon che posso tranquillamente installare il cockpit senza nessun accessorio aggiuntivo, vedremo!
@@giusp1 io non mi sentirei sicuro senza qualcosa nel tubo della forcella. Come vedi a me si è crepata. Magari non si rompe del tutto, in un altro video ho provato a prendere a martellate un residuo di tubo, ma è meglio non rischiare. Se vedi dei video di unboxing di Canyon con l'H31 hanno tutte il reinforcement ring nella forcella.
looks like design oversight with the fancy bar clamping. Makes no sense they don't include the insert, when it costs pennies and doesn't add much weight.
Gosh, with carbon, torque is everything! Can't see any good reason not to just go with finger tight on that cap expander nut. It takes up no load whatsoever. Back in shop days, customers frequently overtightened these expander nuts. They'd distort the wimpier aluminum steering tubes! No no with carbon fiber! One has to have the utmost respect for materials, including in these cases, the technical judgements of the passionate designers. Weight weenies unite! Those Specialized SL7 recalls for potential steering tube failures, and the washer the guys sent you, were merely minor mid-course corrections! Fly on! Gravel bikes may be a return to sanity. Weights are now back in the low twenty pounds, about like when steel was king up to the '90s. Skinny tubing, threaded bottom brackets, back to 12 speeds, now all lined up in back? Maybe trick steel alloys are next! Time for the the latest thing, Reynolds 531 MANGANESE molybdenum tubing, yessir.
Always going to blame the customer for over tightening which I suspect rarely happens as cutomers with carbon frames would be well aware to follow torque settings for obvious reasons, I'd say they should have replaced the folks. If they had provided the reinfocement ring in the first place the cracks would likely not have occurred and yes I am an Industrial Production Engineer :) My additional comment to Canyon would be to stop using customers to do there development work this is a critical part of the bike and this issue should have been found long before this point, very disappointing....
At least in my case they did replace the fork and provided the reinforcement ring. Yes, maybe they should include the ring when they sell the H31 separately.
@@fede1275 Sorry I got the impression you had to buy the folks...everyone else seems to have worked out it needed reinforcement, at this price point should be supplied from the off! Glad you spotted it before any serious failure :)
@@fede1275, no, I have integrated H36 Aerocockpit CF. Unfortunately bike is older than 3 years, so I cannot replace parts with discount. And yes, of course it was without any reinforcement element inside
IMPORTANTISSIMO. if you cut carbon, you must wear a MASK . Carbon dust is carcinogenic. do it outside....so your fork got scared at the end of the video........ it will need a circumcission.......i also uploaded 35 sec. video, Montreal winter road bike scenic with melting snow....if have few seconds....salute ..
German engineering...
I know Maestro, but I really love Canyon and the Ultimate especially with rim brake!
Me too Fede
I don't think that they even have engineers at canyon really 🤔.
Lol... german engineering. I think mass production and quality contol is more a problem. In relation of (canyon) carbon bikes/parts out there the number of fails is very low. In general i have see broken carbon parts from every brand...
Excellent explanation and clear demonstration on how easy Carbon components can go wrong.
Love your sense of humor in your videos 🙂
😄😄
I can confirm that 2022 Ultimate comes with the "reinforcement element" already in place...I was aware of the issue in the past so I double checked before ordering and I would say that tech support was quite honest in saying that the problem was indeed real without this element in place..anyway, thanks for the video! better spreading this type of information than keeping it inside forums
It’s a pity I did not know this in December 2020 when I upgraded the cockpit to the H31.
@@fede1275 the issue with Canyon is a bit resumed with this problem you had...in order to avoid any mishap with a "non-physical" customer service, before buying, I've been lurking forums and blogs for about 8/10 months to discover all the little problems/issues customers had and how they were fixed..you really need to be an informed buyer as the tech support is reliable only at times..the first guy I spoke to had no clue/answer to my inquiries on the subject of the fork-tube cracks, a few days later another one was totally aware of the issue, was really detailed in the explanation and confirmed that the solution was integrated in all new models
I run the PRO headset expansion nut 1-1/4'' 50mm in my canyon ultimate with the H31 cockpit for peace of mind. It is disappointing that Canyon don't supply their bikes installed with an expansion plug to reinforce the fork steerer against the clamping forces (as it is done by most manufacturers). It may works in their computer analysis, but if you consider the manufacturing tolerances and user error (overtightening the fork steerer) this should have been included for additional safety. After all it is in their best interest to avoid disputes with customers, etc.
I was looking at the Pro plug myself, but then I found out about the Canyon ring. It seems a good solution.
@@fede1275 I don't think it can be considered as a good solution, I would still prefer a long expander plug like the one from PRO for 1" 1/4 steerer tubes. The problem with the insert provided by Canyon is that its outer diameter does not match exactly the inner diameter of the steerer tube. This means that the steerer tube, because of the clamping force coming from the handlebar, will still flex until it makes contact with the metal insert. Is that deformation concerning? It depends, but for sure it's a deformation that still happens in an asymmetric manner (because it's not radial clamping). Measure the ID of the steerer tube and the OD of the metal insert...my guess is that there is more than 0.1 mm of difference in their diameters. With an expander plug, the difference is zero, which is what you want ideally.
The expansion nut is round but the cap is a customized shape. How then u fit the cap on the expansion nut?
@@kianannsim I guess you might need to modify the top cap to allocate the larger nut.
hey does the screw provided with the PRO headset fit the Canyon H31 cockpit? or the other way around? I might have damaged the fork a tiny tiny bit and want to run that setup to be safe
Excellent video for me. I’m about to add a VeloBike 18mm extension / 50mm compression plug to my new ultimate. Thanks for taking the time to create and share your experience.
Thank you! Is the VeloBike plug available for 1 1/4 steerer as well?
@@fede1275 Yes. Thanks
Sadly most people do not notice these things either because they do never disassemble their bike or because even when disassembled, they can't notice the notches on the carbon. My roadlite 6 had the same problem. When I removed the stem to change orientation by flipping it to get the riding position a bit less aggressive, I also noticed the existence of no compression plug. And of curse when I remove the stem I noticed the carbon was compressed and notched right along the edge of the stem clamping edges.
Since I also had a bent derailleur (but I have the straightening tool), I decided to fix it all myself instead of contacting them. I went to lathe shop and created a cylindrical element much wider than the reinforcement piece you showed in the video and of height from the top of the tube all the way towards that compression-plug wannabe they placed inside the fork. I've been riding my bike with this almost three months now, no problems.
I'm really disappointed by Canyon. The only reason I would ever return as a buyer again would be due to their prices. Obviously the crew that assembles the bikes is mediocre at best. As for the engineering team, what can one say of an engineering team that uses no compression plugs in forks? Every single bike manufacturer uses one, they cost almost nothing, they barely add any weight to the bike and they provide great protection for the top of the fork tube.
Yes, I believe they relied on the stronger oversized steerer tube and did not add a compression plug. With round clamping stems maybe the problem is not so big, but when the stem/bar have the rear pushing clamping plate, the forces are driven in a narrow point that can cause the damage. In fairness when I smashed a section of 1 1/4 and 1 1/8 steerers, the oversized one was noticeably harder to break, so maybe it would not cause a full failure, but still not ideal.
My late 2021 Ultimate have the wedge from the factory. But thanks for making this video so I could check my bike before something would go wrong.
Remember to add some clear nail polish to the carbon ends after you cut it. This will avoid water or sweat entering and doing damage over time.
Great video!
I removed that plug and installed a Pro expander 1 1”4 50 mm instead on my Canyon Endurance AL with carbon fork.
@@robertkleemann11 👍👍
Like I already commented on your photo yesterday, the same thing happened on my Canyon Endurace but with the standard stem. The problem was (according to the bike mechanic that was subcontracted by Canyon to look at the issue), that there was no spacer on top. I really don't think that this comes from overtightening. I'm glad that you bring more attention to this problem, I only noticed it during maintenance and this can become really dangerous.
Yes, with a round stem and no ring inside it’s definitely better to run a spacer on top.
Same here with the same model. I also asked canyon to send me the reinforcement element that Federico talks about, but they refused.
I am really afraid that it will happen again
@@applesgr I hope you get it fixed, sorry to hear that
Same thing is happening with me. Standard stem on an Endurance. It's cracked right where the stem bolts clamp. I have only ever used the torque wrench that they sent with it. I have it set up the same way it came with no spacers above the stem. Canyon insisted that I overtightened it and will only sell me a fork under their crash replacement program. $325 plus taxes and shipping.
They claim on their website that it is a 'compression plug', with those exact words. But its so measly that I almost don't know why they bothered. Is this to save weight or something.
I almost bought a canyon and at the time it just didn't look right to me. I was going to purchase the 50mm deep plug from pro. Not many brands make a plug for the 1 1/4 oversized steerer.
Look at the replacement compression plug that specialized now ships on the tarmac after the voluntary recall. It's massive, something like 70mm deep (as it should be).
On all FIVE of my Canyon's I removed that plug and soft top cap and replaced them with the Pro 50mm expander and top cap.... also Canyon headset bearings and really badly greased from the factory and tend to rust within the first few months. Again, changed them and greased them with no problems.
Having watched your video I contacted canyon who is supplying me with the reinforcement plug free of charge. Thank you 😊
Great to hear that 👍👍
Well explained Fede , I have to admit I’ve been a bit sceptical about canyon bikes & their issues. Especially the bar issues etc. But I guess on a good note their customer service has been top marks . Good luck with the cutting of the fork !!!
Thank you, will try to to mess it up 😄
So many Thank You, Sir.
Most informative, - that should have been delivered by Canyon
Very informative and well explained video for canyon users. You are lucky for noticing it before anything bad happens and you have a youtube channel as canyon do not provide free forks or even simple spacers for everyone who has the same problem. One of my friends with the same one piece h31 handlebar had to pay for the new fork. I have an ultimate with the h36 with a different bolting pattern so I did not have the same problem however as an engineer I always used a spacer above the stem for the reasons you explanied. An other problem which I had was failure of the fixing spacer at the bottom with a bolt on it. This is a very fragile plastic part which eventually fails by cracking even if you torque it less than 2 nm as stated. I had to pay for the whole spacer set as canyon was not helpful again.
I can genuinely say that Canyon have always been supportive when I needed them, even before I had the channel. This is my first major issue though. I have been reading different interactions and it's difficult to judge from the outside. I definitely believe they should add the ring to the H31 spacer kit, as a potential upgrader will fit it on a bike with the V13 stem that do not come with it.
do you know how much is a new fork to road bike?
Watch all . This is not criticising Canyon. Good advice Federico. Thanks
👍 I might add that in my opinion Canyon could include the reinforcement ring in the spacer kit for the H31 if sold separately.
This was a great video and demonstrated the exact issue I am now dealing with on my Endurace CF SLX with the integrated head set. Thanks for the great info and the humor sharing the details.
Thank you, maybe you have an earlier bike before the introduction of the reinforcement ring. Hope you can sort it out!
Very well presented. Yes check your equipment! Cutting your own steerer is a good idea. Just take your time and wear a mask. Thanks
Very well detailed and nice to see Canyon have responded to yourself and addressed the issue. I do think it would be better if they fitted an expansion bung as standard though. It sounds like an 1" 1/4 bung will be difficult to source.
Federico, once again you are reading my mind! I was literally just researching the H31 ergocockpit and very much planning to upgrade to it. However, with that clamping mechanism, I may well reconsider. I do love those swept-back tops though!
The H31 is amazing, nice to look at, light and comfortable. I feel more comfortable with the ring insert now.
@@fede1275 I wonder is the ring supplied in the cockpit or the spacer pack from now on?? Did Canyon supply it with your replacement fork?
@@davidmoore4661 the reinforcement ring is fitted as standard on new bikes with H31 or CP10 cockpit, not sure if also on H36. The spacers kit does not come with one, only with a replacement expander element for the top cap.
Federico. cracking video very well explained what happens in that area. had issue with new Ribble bike delivered last summer. play in headset couldn't tighten up. I ended up over tightening the bolt at top of steerer and sheared it Total panic. luckily managed to sort it. just didn't realise importance of all that stuff. my new bike has fully integrated bar stem and mentions about steerer BUNG so will be taking extra care this time. with help of your video. 👍👍👍 many thanks
Great that you managed to sort it out! I was looking at Ribble for a while before going to Canyon. Nice bikes!
I also have the same problem with my aeroad fork. And tq for this video as I was just don't know what to do . Thanks again . Will contact canyon soon.
Hope you get it sorted!
Fede. Excellent video. Every Canyon rider needs to understand these issues. Well presented. My only issue is that with every bike part black they were getting lost amongst your black jersey background. Perhaps a lighter grey or a more colourful jersey for future appropriate videos. The man in black needs to be in colour sometime !!
I know, I only realised it afterwards! I tried to add more pictures 😄
I had this same issue with a Grizl and a standard clamping stem. No offer from Canyon to replace the fork. I had to buy it. I'd like to fit the reinforcement sleeve with the new fork, but I doubt the top cap will fit. BTW, I believe (but could be wrong) that the protruding part of the top cap is supposed to be inserted down into the steerer slightly giving it some reinforcement. This means that you have to make sure not to allow too much height difference between the top of the steerer and the top of the stem. Seems to me that they have to be nearly flush. This would be extremely easy for Canyon to fix simply by making the protruding part of the top cap longer by several millimeters.
Yes, even if the standard clamping stem should be safer, I heard of some instances like yours. With the reinforcement sleeve you will not be able to use the original top cap, I bought a flat carbon one that clears the ring. The top part of the ring is slim enough not to interfere with the top of the stem. You can also fit a small spacer on top to compensate if needed.
and how much is new fork?
@@LuiS-kj1qe as I mentioned in the video Canyon supplied the fork as they acknowledged the issue. I believe a brand new fork list price is around £490.
Aloha from Maui, I have the 2021 Endurace with standard stem like your original setup exactly. It came with a 5mm spacer on top but I put a 10 and that 5 to make 15mm on top right off the bat. The so called plug is right around the top bolt on the stem I feel safe about it I was going to put a real plug but just held off. If I ever cut it I will always have a 5mm spacer on top, I am strongly against no spacer on top because the stem is only 97% on the steer tube with the couple mm you need to clamp it down together. Your new bar set up may have to run no spacer on top but if you could I would but that new insert they gave you might fix everything I'd get one but my stem would be below it and most likely I won't cut it for resale. So far no problems with my steer tube after 3500 miles and I'm your size only my seat post creaks and sounds like the BB but if I clean the post and inside every couple rides its fine the bike feels brand new still. 🤙
I'm considering running 5mm top spacer, yes. Flush cap is nice, but maybe it's safer with the spacer on top.
Super useful info Federico, Thanks
Brilliant, thank you. I hope your fork did not run far 😀👍
Great explanation. I just took off my CP10 stem to see why it was feeling a little “crunchy.” Same failure and I’m religious about using a torque wrench, especially on carbon parts, especially on my stem! We’ll see what Canyon says. My bike is a 2018 or 2019 so it’s got a lot of KMs. (Not KOMs 😅). I don’t really blame Canyon particularly. Every manufacturer has similar issues occasionally.
Fingers crossed, I hope you get their support!
Hi @matthewhughes5472! Did you already hear back from Canyon? Unfortunately the same thing happened to me as well... Canyon offered to send me a new fork, but they charge almost a third of what I paid for the whole bike (Ultimate CF SL 7 Disc)! Now I'm wondering whether I can massively reduce the stack on the bike and cut the cracked part of the steerer tube instead. Curious to hear how things are going at your end! Cheers
@@smann7992 yikes! No, I’m still waiting to see if they have an extra fork around. Were you the original owner of the bike? I’ll let you know if they quote me a price.
@@smann7992 Canyon found me a fork within 24hrs. Not a matching color, but it’s black so I’m happy. I have to pay $499 up front, but they will refund it to me once my old fork is removed and destroyed (or more destroyed). It should arrive in a few days.
I’m the original owner of the bike, and it’s a 2019. I’m very pleased with the outcome. Great customer service.
@@mattthehoople Thanks a lot for the update -- that sounds like an excellent solution. Unfortunately, even though I'm the original owner of my bike, it's too old to fall under warranty (I bought it new in 2017), so I'll have to pay the full price... Might do it anyways, though, as the bike seems pretty useless otherwise.
Good luck with the installation of your new fork and happy riding!
These engineering "after thoughts" are so unbelievable. It's mind boggling that they believe a hollow steerer can with stand compression forces. Jeez. Be safe out there doc 🚲
It seems that normal stems don't have problems, I believe the issue is prevalent on the clamps with the back plate. That's why they added the ring.
@@fede1275 it seems to me that the steerer plug is only slightly better. Every component must be checked and rechecked constantly 🙄 London roads with the potholes are also are part of the problem. Grrr
@@gw4550 and they are getting worse 😖
I have endurace. By canyon maintanance book they propose you have to change fork every six years. When I contacted them that I want to by new fork they said we do not sell forks after waranty period. At that time I could not buy any where 1 1/4 flat fork. Most forks are 1 1/8.
Very bad experiance with them. Original compression plug died so I took Pro one. With my fork everything is ok, bit if you want to buy fork from them they do not sell.
When I said them that I will put the info on web they offer me 40 Euro gift card. When I refuse it they offer new fork for 280 euro. Frederrico, did you buy fork or it was free?
Thank you for your great sharing. It's good to know and I learned something new today. 👍👍
Good that you found this out before it failed on a ride. Canyon have some odd design theories - never understood their steerer/stem arrangements including that weird allen keyed adjuster (do they still sell that?). I ride Giant and my TCR has an oversize steerer too, with a stem plug - nuff said! Cutting a steerer is very easy with a clamp/guide and a suitable hacksaw blade (total outlay < 20quid). Just measure 15 times before cutting!
Indeed! They don't use the allen key adjustment anymore, the steerer is more conventional apart from the missing compression plug. I guess mine was an odd combination as I upgraded the bar/stem later on, but maybe the ring should be supplied.
oh! MAN! i have the same problem. I didn't know about Canyon EP1297-01 Wedge Extention, just used a piece of metall pipe
after repairing fork on the aeroad slx, decided to place the order to 2 pieces of extensions to protect speedmax fork too.
Yes, I guess the problem started (or got worse) with the new cockpits with rear bolts.
Thanks for that important information. I can confirm that the issue is also on the round stem. My cracked likes yours. I tighten the bolts with torque wrench only, canyon is blaming my fault. It´s the same words as your answer..
**** Canyon, that´s bullshit. First and last bike of this brand.
I can understand your disappointment of course. I had a different outcome and still enjoy my Canyon Ultimate, but I can see why you are not.
Thanks for your detailed and clear video👨🎓! Canyon was generous to give you a new fork; they could blame the damage of the steerer to the mechanic who installed the integrated cockpit...
You are right, but I also just recently bought another bike, so may that also played a part.
Thx. I had the same Problem wirh my grail cf and find also see this as the root cause. I also get a new fork but without the part you show. I ask them now why they just send the fork and not the preventio. When i don‘t get the part from canyon (5€?) i will glue a stainless steel pipe in there
Good locking out, I run H31 on my ultimate and don't have the plug.
You might have upgraded as I did and did not know they added it to the new bikes!
Nicely explained, good job in checking this out!
I am worried that my steerer is damaged and don’t really know what to do, because I feel insecure riding my bike now. I hope maybe you can help me to determine what I should do.
I was at a bikefit and apparently my stem has to be set way lower than it is by default. So I took out some spacers and because of the pin-system, they couldn’t be placed above the stem, so I left the part of the steerer above the stem blank.
I rode some time (quite hard) for a few weeks until I felt like this was a good position and looked up the manual because I wanted to gather information regarding the whole build up, for finally shortening the fork steerer.
I discovered, that the manufacturer explicitly states to NOT leave space above the stem (even with spacers) because it damages the steerer tube. (Most likely because the compression device isn’t long enough to work against the stem pressure there.)
Also I red a lot of things on the net from bike manufacturers explaining how sensitive those carbon steerers are to pressure. And now I am feeling unsafe riding my bike, even though there are no visible errors, but I also read carbon doesn’t tend to show signs of damage.
I would change the fork ASAP, but apparently, there are no forks with 1 1/4 to 1 1/2 anymore, at least not in my region or online.
Shouldn’t I be so worried? I mean are all those saying from bike companies and mechanics made up?
please help :( I wanna ride again but I am very confused.
Thank you for the confidence in my judgement, I need to remind you that I'm not a carbon expert. Having said that, did you notice stress fractures on your steerer? Are you just assuming your steerer is damaged? If you are worried have it checked, but if it looks fine it probably is. What stem are you using? Do you have a reinforcement ring in your set up?
I sat through the whole thing, very entertaining 16.21 minutes to explain a fractured steerer
Good explanation and excellent use of toilet roll thingy!
By Federico aged 4 and 1/2 😄😄
Great presentation, really like your style
I had the same steerer failure. The internal of the steerer didn't show crack but where the external meets the clamping wedge had a dent. Canyon Ultimate CF SL 8.0 rim brake 2019 model with CP10 handlebar.
The compression plug is in the middle of the steerer, not in the clamping area. That's a strange/stupid design.
I emailed Canyon when I found out about the problem last year in September and had some debate about whether it was a user error with the wrong torque or a design defect, they finally agreed to send me a new fork but there was no stock at the time. Last week they finally shipped the fork.
In the meantime, What I did is cut the damaged part of the steerer and put a regular Giant OD2 stem tilting upward to compensate for the loss of height.
This is because the plug inside Canyon forks is not designed to compensate for the clamping forces, but only to pull up the fork and compress the bearings. It seems that they introduced the ring in 2021 as both CP10 and H31 have the same clamp.
@@fede1275 Although I like the sleek look of integrated handlebar and the comfort of the aero/flat section to rest your hands, I'll stick to normal bar/stem combo in the future. To be honest I still think that ring is too shallow to fight against the wedge. I'm curious if you're able to use a regular expander plug instead of that ring.
Great video, i would recommend you to use a proper torque wrench instead of the plastic thing, especially on carbon. I don't trust plastic since it can wear out easily...
Thank you, I also have a proper one I did not show in the video.
CF SL8, I went the other way around, swapped CP10 with V13 + round handlebar combo because I needed to shorten the stem and fit aero bars (cant fit anything on cp10). It was a nightmare to reverse engineer Canyon solution, why is this here, what is that for etc lol. Although Canyon didnt say anything about the metal sleeve reinforcement (EP 1297-01) for v13 I decided to put it anyway and watching your video, it's good that I did 😁 Thx 👍
Well done!
Great video again dude! I guess this is why the H31 cockpit is half price on the Canyon shop now! Where did you get the reinforcement part for the steerer tube from, I can't see it on their website?
Thank you! Pity the discount is available only on some sizes, otherwise I might have bought another one! Canyon don't list the reinforcement part on the website, will need to ask directly.
@@fede1275 Yeah that is a shame, but thank you for the tip re: the part, much appreciated! :)
Thank you very much for this useful information 👏👏👏
Thank you for watching!
Had exactly the same problem. At the beginning they blamed me for overtightening the stem and offered me a replacement fork for 160€
Finally they changed the fork for free. The problem is I am very nervous that this will happen again. It seems like a weird design...
I appreciate their customer support but I don't know if I i would buy again.
had same problems - same offer from canyon - seems inevitable will happen again
@@garethbater6900 do you have the v13 stem or the intergrated cockpit?

Ciao Federico, ottimo video analisi. Ho avuto un problema simile con una canyon ultimate venduta con manubrio integrato CP10. Il meccanico dopo aver tagliato la parte in eccesso della forcella non ha inserito il “wedge insert” di rinforzo e la pressione ha danneggiato, come nel tuo case study, il tubo forcella. Per curiosità nel tuo caso canyon ti ha fornito una forcella nuova in garanzia? Grazie mille e complimenti ancora per l’analisi dettagliata.
Ciao, grazie! Si, nel mio caso sono stati molto efficienti, mi hanno prestato una forcella usata che avevano a disposizione fino a che non e' arrivata quella nuova in garanzia, per farmi usare la bici nel frattempo. Vicino Londra c'e' un centro Canyon di assistenza. Poi ho restituito quella e tenuto la nuova. So purtroppo che in altri casi non sono stati cosi' di supporto. Adesso credo che abbiano esaurito lo stock per le bici non piu' in produzione.
Canyon insists in proprietary parts with designs significantly different from the rest of the industry and that comes with its own risks. Going with standard designs means using something that has been widely evaluated and tested. on the other hand, coming with a completely new design may mean that there are cases that haven't been tested as exhaustively as they should, due either to oversight or because they simply didn't existed at the time (as was the case here). Canyon is learning this the hard way with their shifter clamp on their latest Aeroad handlebar fiasco, the issues with the Aeroad seatpost design or the case shown here.
I know, but I thought that on a more traditional design like the Ultimate there were going to be less of these problems.
Others have recommended acquiring a higher quality torque wrench...I agree.
I got a better one I didn't show in the video. Don't think that it's a torque issue though.
Grazie tanti Federico! This is so timely. I just bought a brand new Endurace AL 7 as my winter bike and it indeed comes with a carbon fork/steerer. I was trying to find in the Canyon website this reinforcement plug (EP1297-01) for the 1 1/4" Canyon steerer you mentioned in the video without success. Could you provide a link to it?
It's not listed it on the website. Might need to try to contact them directly.
thanks for this! I have a h31 so will be checking it.
Yes, better to find out if you have the ring.
@@fede1275 luckily no sign of cracking but have contacted canyon to get the wedge cap. Thanks again!

Hi! I have an Endurace CF 7 with a V13 stem. I want to install the Wedge extension like you. What top cap did you use? I don't think the original from Canyon fits
Yes, Canyon top cap would not fit the reinforcement ring or a compression plug. I got a Carbon Ti X Cap for 1 1/4 steerers, but there are other flat caps available on the market for the larger steerers.
Very informative. Thank You
I now have two steerer fork failures on my endurace with the H31 cockpit, stem bolts tightened always using a torque wrench and to 5nm - imo they have a design issue here

Federico: Do not cut the new steerer tube in one go. Stop before cutting completely through, rotate it 180° and cut the rest. Reason: It may splinter otherwise. I had that recently, and it is a pain. And: Measure twice before cutting ;-)

Yeah damn sadly this happened to me recently…
I wonder if I can put in that reinforcement ring and continue riding or do I need to get a brand new fork now if cracks already exist?
Not sure really. I have a video where I hit the steerer with a hammer and it's not easy to crack. In theory it should not collapse with a proper compression plug or metal sleeve inside, but it's not a comfortable thought thinking it is actually cracked.

Do you know how I can find a fork that fits with this 2019 Canyon Ultimate CF SL? Hope all is well with you man and keep it up as always!@@fede1275
And the second fail of canyon !!! I received my new canyon aeroad the slx DI2 version in January 2021 and I have already sold it! less than 250 km driven !!! First had contact about the wear on the seatpost. then the broken bicycle handlebars! And when I took it to the canyon service center they discovered two cracks in the carbon of the rear uprights . got a new frame but confidence was gone hence the sale.
It's a pity, I really like Canyon and their bikes, but sometimes products have issues. It happens with a lot of other manufacturers though.
Hi I just got my h31 few weeks ago and did not received this small part , is it available anywhere on canyon website ? I found only one for 1 1/8 tubes Btw great videos and content 👍🏻
Thank you! The reinforcement ring is not listed as a spare part, it's fitted as standard on new bikes that come with CP10, H31 or similar rear clamp cockpits. You would need to contact Canyon directly to get it. It's called EP1297-01.
Hi. When you make a mark on the steerer tube against the top of the stem, how many mm below that line do you cut? I see that some canyon models don’t have expander plugs but rather just wedges so you don’t need to accommodate that few mm of the expander plug.
Your aim is to leave 3mm from the top of the steerer (of the compression plug if there is one) and the top of the stem, assuming that you have a flat cap, to allow for the bearing compression. If the top cap shape is domed and comes down towards the steerer you might need more space, as the steerer might hit the cap before the correct adjustment. As you mentioned most Canyon don't have the expander, but just a bung deep down to engage the top cap bolt and the top cap design should not interfere with the steerer when compressed. I used the metal reinforcement ring and I had to use a flat cap, not the original one.
Hi Federico! Thank you for the very interesting video! Do you have any idea of the internal diameter of the wedge extension part? I am considering to fix it on my Grizl steerer tube, but then the normal cap would probably not fit anymore.
Hi, I haven't measured properly the sleeve, you might want to check the internal diameter of the steerer on your bike. With the Canyon part the round cap would not fit.
@@fede1275 thank you, I agree! I will check if there is by any chance a cap available on the market that might fit this solution!
One additional question, I was watching the video again and noticed that you mention using the wedge extension with a V13 stem...how did you solve the cap compatibility issue? Did you find another cap model that would work? I searched a bit but I think I might need to 3d print one myself...or 3dprint a compatible sleeve, might be easier😂
@@bogdanc2309 So I refer to the wedge as the small compression plug that sits inside the steerer tube, around 3cm in, and is needed for the top cap bolt to screw in and set the bearings preload. This does not touch the top cap. The reinforcement sleeve sits at the end of the steerer and will clash with the standard round top cap. In my V13 set up I bought a flat top cap in 1 1/4" from Race Ti, but you can find some more in the market. Being flat helps not touching the inside sleeve.
@@fede1275 great, exactly what I needed to know! Will have a look at their caps, thanks!!
I check the steerer tube 3x per season... and have been using longer compression sleeve, and never put spacers above the stem - never.
I agree with frequent checks and longer sleeves, if they fit your bike. A 5mm spacer above the stem can give a better clamping position and the steerer is not pushed where it is weaker. Bontrager also mention the need for 5mm below and above their stems. Spacers above the stem are dangerous when they then place the stem clamp outside of the intended compression sleeve. For Canyon there is no such a thing.
I dont understand why they dont fit compression plug. If they decide to make steerer bigger, they shouldve manufactured a matching compression plug. It’s been used for many many years and it’s been proven to work. I dont get why canyon decided to forgo the compression plug.
Fede, very interesting. Thanks for sharing. So glad it didn't fail on you mid-ride.
Did you find the runaway fork?
Not yet 😂😂
How did you remove the steerer tube "expander"? I understand that once inserted it would be wedged if pulled up. How can you relax the wedge to be able to pull it out?
It's not easy. I first released the nut inside the wedge without removing it. Then I used the bolt you usually use with the top cap to engage it and tap it lightly to get it unstuck. Then with a pair of pliers applied to the bolt I managed to remove it.
My Canyon Endurace AL 7 comes with 1 1/8" steerer fork, not the 1 1/4". Still the space between the top cap and the wedge is huge ( at least 5cm). Canyon doesn't sell a solution like the one you showed at the end of the video for 1 1/8" forks. Should I use a traditional expander plug?
I didn't know the AL 7 came with a 1 1/8" steerer, what is the stem type you have? Definitely the smaller steerer is weaker, but please double check for me the steerer size.
@@fede1275 The fork is the Canyon FK0042 CF Disc with 1 1/8" steerer tube. The stem is the standard aluminum (non-integrated) Canyon V15 with head tube diameter of 1 1/8".
@@The_One-Eyed_Undertaker with the smaller steerer a proper compression plug is needed, to reinforce where the stem clamps. I would definitely get a traditional long plug to cover that area and remove the small plug. I smashed with the hammer the two steerers in a video and 1 1/8" felt much weaker.
@@fede1275 Thanks Fede! Is there any brand /model of compression plug that you could recommend or have good experience in the past? I have replaced basic parts like tubes, tyres, chains, cassettes and gear cables in my bike and know how to bleed my brakes. But I have never done anything on my head tube yet...🙄
@@The_One-Eyed_Undertaker you will have plenty of choices in that size, but you would need to check if you have enough space between the top of the plug and the cap once installed. I prefer flat caps as it's easier to measure, you need 2-3mm free space to preload the bearings. If the top of the plug hits the bottom of the cap you would not be able to preload with enough tension.
Very interesting Federico. Nice to see the new table being put to good use. Is that an industrial safety blanket?
😂😂 Mrs not pleased!
Thank you for the Video 😃
Thank you for watching 👍👍
great video ty!!
👍Wouldn’t ride without a good expander plug.
I can understand! Check my video where I smash the steerers with the hammer!
thank you very much ! I have same problem with aerokokpit, please where I buy the plug EP 1297-01 ? thank you :)
I don't think it is available on the website, might need to contact Canyon directly.
@@fede1275 they send me this plug but is it enough ? or better longer compression plug ? thank you
@@martinrazus6365 I'm following Canyon advice and going with the reinforcing ring.
I am height 175cm and inner leg length about 80cm. Which size should I choose?M?S? I used M size in my giant tcr.
I would trust Canyon's website, with your measurements they suggest size S.
Great video ... and nice hint - not going VEGAN yet- ;-))) I really had to laugh loudly.
But i have to say. I swapped on my new Dogma F the steer plug over the standard one which came from Leon Bikes or better pinarello factory stock to an oversize Dedaelementi Plug! Just for safety reason cause i am more on the heavier side than a durianrider lean shape !
😀😀
I'm surprised Canyon were so helpful considering their warranty department manager was popular a while back for rejecting a warranty request on a BB shell that was out of their stated tolerance range, maybe things or the manager have changed since... Good that they fixed it for you. At least you're not out of pocket for something they know they have done wrong, the fact they didn't ask you to pay is an admission of that IMO, but they still like to play the old trick of blaming the users overtightening bolts ofcourse, have to save face I guess.
Yes, I have to say they were very good and quick to resolve the issue. Maybe if they say that that cockpit clamp also needs the reinforcement ring they would then need to send one to all the bikes they shipped before without it. New bikes with that syle of clamp now come with the ring.
@@fede1275 essentially they are using customers for their R&D and testing and then quietly implementing changes when the field test results come back as "if someone faceplants the floor we will be liable due to engineering negligence" top company.
@@mrnobody9821 unfortunately it does happen with a lot of companies 😖
I had a similar failure with my Canyon Grail CF fork.
Hope you got it fixed.
@@fede1275 It's taking a bit longer (already a month of back-and-forth with the customer service) to get it sorted as it is already past the 2 year warranty but I am claiming it within their "6 year Guarantee." Initially they offered a crash replacement but I pushed back and escalated the issue. After more than a month since I made the claim they finally offered the fork for free.
@@rafaelveloso7945 👍👍
Very helpfull thank you
👍 👍
Did canyon replace the fork free of charge or did you have to pay? They’re offering to replace mine as a crash replacement for a discount over the normal price. But this doesn’t seem quite right.
They replaced the fork free of charge. I believe the problem from their side is that I fitted the H31 at a second stage. On new bikes with H31 or CP10 they also add the metal ring, but it is not supplied when you buy the cockpit separately. What happened to your fork and what setup you have?
@@fede1275 ultimate cf SL with a cp10. I got the cockpit from eBay wanting a change from the original. it didn’t come with the metal ring, nor did it seem the previous owner had one supplied with it.
@@edmorris5433 unfortunately it seems that stems that have a round clamp can still work well with steerer without a compression plug. H31 or CP10 with the rear push clamp do put too much stress on the steerer without additional inside support.
Nice durianrider reference!
😂😂
Salve, è quindi indispensabile montare quell’accessorio sulla forcella?
Ho ordinato un cockpit H31 non sapendo di questo problema, ora ho chiesto delucidazioni a Canyon!
Si, anche io ho preso l'H31 come upgrade e nel kit con gli spacers non c'e' in reinforcement ring. Canyon con gli stem tradizionali non usa nessun rinforzo per la forcella: in questo caso lo stem classico ha le viti al lato ed il carico e' radiale e meglio distribuito. Con l'H31 le viti sono dietro e il carico e' diretto solo sul retro dello steerer. Canyon su tutte le nuove bici con H31 o cockpit simili con le viti dietro monta il reinforcement ring per supportare la spinta dell'attacco. Secondo me dovrebbero includerlo se si acquista il cockpit separato.
@@fede1275 grazie per la risposta! Mi hanno appena comunicato da Canyon che posso tranquillamente installare il cockpit senza nessun accessorio aggiuntivo, vedremo!
@@giusp1 io non mi sentirei sicuro senza qualcosa nel tubo della forcella. Come vedi a me si è crepata. Magari non si rompe del tutto, in un altro video ho provato a prendere a martellate un residuo di tubo, ma è meglio non rischiare. Se vedi dei video di unboxing di Canyon con l'H31 hanno tutte il reinforcement ring nella forcella.
@@fede1275 grazie ancora, saresti così gentile da indicarmi il link di un video dove si vede? Così magari segnalo. Se puoi, ti ringrazio in ogni caso
@@giusp1 qui si vede bene, minuto 1.55 ruclips.net/video/aFsBnuUre3g/видео.html
looks like design oversight with the fancy bar clamping. Makes no sense they don't include the insert, when it costs pennies and doesn't add much weight.
Yes, I believe it should be added to the H31 spacers set.
100% Thankyou
Gosh, with carbon, torque is everything! Can't see any good reason not to just go with finger tight on that cap expander nut. It takes up no load whatsoever. Back in shop days, customers frequently overtightened these expander nuts. They'd distort the wimpier aluminum steering tubes! No no with carbon fiber!
One has to have the utmost respect for materials, including in these cases, the technical judgements of the passionate designers. Weight weenies unite! Those Specialized SL7 recalls for potential steering tube failures, and the washer the guys sent you, were merely minor mid-course corrections! Fly on!
Gravel bikes may be a return to sanity. Weights are now back in the low twenty pounds, about like when steel was king up to the '90s. Skinny tubing, threaded bottom brackets, back to 12 speeds, now all lined up in back? Maybe trick steel alloys are next! Time for the the latest thing, Reynolds 531 MANGANESE molybdenum tubing, yessir.
Back to the future 😂
Always going to blame the customer for over tightening which I suspect rarely happens as cutomers with carbon frames would be well aware to follow torque settings for obvious reasons, I'd say they should have replaced the folks. If they had provided the reinfocement ring in the first place the cracks would likely not have occurred and yes I am an Industrial Production Engineer :) My additional comment to Canyon would be to stop using customers to do there development work this is a critical part of the bike and this issue should have been found long before this point, very disappointing....
At least in my case they did replace the fork and provided the reinforcement ring. Yes, maybe they should include the ring when they sell the H31 separately.
@@fede1275 Sorry I got the impression you had to buy the folks...everyone else seems to have worked out it needed reinforcement, at this price point should be supplied from the off! Glad you spotted it before any serious failure :)
@@peteturner8493 yes, in my case they were very supportive
! Watch out as regards inhalation of the carbon steerer dust !
Will mask up, thank you!
good mtb parts rigid fork is best in road
the cover image for this video looks like you're loading a shotgun ))
New channel idea 😂😂
That actually happened to my Canyon Ultimate CF SL 8 bike. Now Canyon offered me to change fork for 400 euro 💀
Ouch! Did you have a standard stem without any steerer support?
@@fede1275, no, I have integrated H36 Aerocockpit CF. Unfortunately bike is older than 3 years, so I cannot replace parts with discount. And yes, of course it was without any reinforcement element inside
@@lZazZl I see, it must have been before they introduced the metal ring as standard.
IMPORTANTISSIMO. if you cut carbon, you must wear a MASK . Carbon dust is carcinogenic. do it outside....so your fork got scared at the end of the video........ it will need a circumcission.......i also uploaded 35 sec. video, Montreal winter road bike scenic with melting snow....if have few seconds....salute ..
Yes, I did it outside and masked up. With gloves as well. Nice video, would also be nice to fly in one of those hydros!
