All Scott bikes are assembled at Giant factory in the Netherlands. I worked there for about 2 years and I saw most of Giant / Scott / Bergamont and in the past Trek were assembled the same way. Because factory was basically hiring everyone from the street and pushing them to the limits in order or archive the lines targeted , the quality of the assembly was terrible. Installing the BB careful was simply not possible with such speed and whenever the worker would find out that he damaged the BB during assembly he would not say anything to just keep the line running and keep his job.
It’s simply too tempting for brands to let their frames make for a few hundred bucks in Taiwan …and sell them for 10x in the „first world“. So tempting that even LVMH highly participated in … or even took over Pinarello completely just recently!
In my time as a bike mechanic with these kinds of pressit fit BBs I tended to use a Wheels manufacturing press 9 pro kit, this allowed to slowly apply pressure evenly rather than punching it out with our standard park tool and blowing the cups to bits. even managed to get loctited bbs out in this fashion.
I have a Canyon with the same issue and mine is aluminum. I had to remove some material and use a thread together bottom bracket. You would think with an aluminum bike that they could make a perfectly round BB. My guess is that it was perfectly rounded before they welded it all together.
This is 100% something that should be brought to Scott's attention. Like almost all big manufacturers, they all have issues. I own a Scott Foil, no issues with mine, but my next carbon frame will be from Time.
Most companies today use pressfit bearings in their carbon frames. Aluminum in a carbon frame has other disadvantages: electrochemical corrosion from the two materials, different thermal expansion.
So, if you know that this "defect" happens to all brands why is the title straight up pointing at Scott as if they are the only brand to have this issue? Sure you're showing a Scott bike in the video but again, this happens during manufacturing and should be covered by warranty especially if it's within the warranty period. No brand in any market mass produces 100% perfect products 100% of the time. The title of the video should be "Manufacture defects on high end bikes beware"
Interesting point Sir. However, It definitely doesn’t happen with all Brand’s, only the ones that use press fit carbon BB shells and Scott and Giant are probably the most likely to make this mistake. As for warranty, it’s very difficult to get. I had some bad experience with getting carbon manufacturers to uphold their warranty in the past. My advice is avoid this sort of bike if you want to be free of this kind of problem. After all, they all seem to have misshapen BB shells to one extent or another… it’s just this one is particularly bad. Thank you for your comment and safe riding! 🙂👍🏻 PS. The Title is perfectly accurate. I would never buy a Scott bike. Haven’t seen one made in the last 10 years I’d want to spend money on. I did see a 15 year old Scandium frame with a square taper BB and some classic Dura Ace on it once. That was nice.👌🏻
@@reginaldscot165 It does. Defects can occur with alloy, steel, titanium and carbon. Carbon is plastic so my guess is that it may be more prone to having warped during the curing process but either way, frame defects occur in every brand. From their very cheap models to their high end. Regardless, you agree that this is not a “Scott” only issue. My point I was trying to make was why did you single out Scott? The wording of the title: “Scott Bikes, why I would never buy one” Scott isn’t the only brand that produces carbon frames. They are not the only ones with imperfect BB’s. As for warranty if the bike was bought through a bike shop take it back to them to handle the whole thing. If this bike was bought online then repeat the steps. If the bike was bought used second hand then yeah that’s a big problem. In the video you stated the bike was fairly new. So, my mind says “OK, don’t fix it yourself, contact Scott with proof of purchase”
Scott bikes are junk. Poor fabrication quite often and silly prices. Only a complete idiot would pay the shill prices they ask for one of their garbage framesets. LOL

Have never had an issue and its been a dream to build/ride/maintain. Have also ridden a Scott addict for a while, again no problems or issues with it whatsoever.
Well 1) you didn’t pay full price so the cost/value benefit is already way better. 2) you bought an older bike that was probably better made than the newer stuff. Also have you ever checked the BB? Is it a press fit and has it been checked for size? 🙂 I’m glad it’s working well for you and I wish you safe riding! 👍🏻🙂
@@reginaldscot165 it is a pressfit (bb92) and haven't actually needed to swap it out yet. It is older but Scott is still using the same carbon today as they were a decade ago.

Hambini and I have 1 or 2 things in common it’s true… 8.4kg is not unusual nowadays, most of the off the shelf carbon bikes in ultegra we get in for service are in the 8kg+ mark.

I'm new to bikes but I need a good second hand bike which brand is not overpriced and not with complicated issues do you think I should check,thanks for the heads up with Scott bikes
All modern carbon bikes have issues and if you buy second hand expect some issues. Budget 20% value of the second hand bike price for emergency repair and servicing. As for what to buy, a viewer in the US just showed me their second hand 90s Litespeed titanium road bike. That’s basically bombproof. But any bike is fine If it’s second hand and the price is right. 👍🏻🙂
Looks like you just have a bad bike frame there. I have several carbon frame bikes over 10 years and they get serviced every year. Never had a complaint from any workshop, all good. My Scott Addict is an amazing bike to ride too. I look forward to riding it every day it's so awesome.
@@reginaldscot165 I work in engineering manufacture, and understand you get variability, thus in your job you will obviously see some bad cases over time too, you must handle many bikes daily. I know most carbon frames are made in China and shipped to Taiwan for finishing, as is our client currently. They are hand made so you are bound to get some come through bad. But in terms of actual ride and handling, I have found Scott to ride brilliantly, stiff, handles really well. No complaints, and as I said I love it. Like going out in a new sports car. I guess I've been lucky to have good builds. You call them plastic in your video, which is a bit unfair. Carbon is a very strong and very versatile material. I'm actually working on a McLaren carbon bike frame as we speak, a new hardtail in development, so am involved with it's design and build. I will raise the issue you brought up with the bottom bracket in your video with my colleagues for ref. However the Hardtail bottom bracket is quite a bit different to a road bike lol. In fact as an after thought, your video here ought to be sent to Scott so they can investigate the poor manufacture issue you've found.
Hi Reginald, thanks for your video. I would be interested in buying a Scott Foil 10 2017 or a SuperSix Evo Hi MOD 2013, but after your video I'm a bit worried😆. Should the Cannondale be more mechanically appealing? It's also a 400 km bike, but the Foil is modern and aero...
Forget both! (Although the Evo is better) Aero frames make basically no difference. Wheels and body makes a massive difference. So if you are young and want to go fast buy stiff aluminium and save the rest of the money for better wheels and aero kit! If you want a better all round bike, but steel or titanium. Forgot carbon, I’m 38 and I regret all the money I wasted on carbon frames. I should have just bought titanium to begin with. 😁👍🏻
@@reginaldscot165 Wow, I didn't expect this type of advise, especially in a world of carbon frames!! And also make me astonished know that aero frames do not make differences at all. I come from the '10 era of cycling, when I was 10 and race with bike was my sport, in this years I've lost some notions on new technologies. For sure I will save up money for aero wheels, better if tested in wind gallery from brands who certificate that. Thanks for sharing us your experiences.
Could you ream out the bb. I own a Scott USA as they used be called and I have had no problems considering it’s an old Mtb and the lightest in it’s day. But looking at todays Scott website and others they have doubled in price and are loaded with thinks that are of no benefit to your average rider.
Metal can be reamed easily but normally it’s not needed on metal BBs. The problem with carbon if you try to ream it is it would grab or snag and probably do damage. Sanding is much easier.
Now from what I have seen over the last few years if you want carbon you will need to dig deep in your pockets and spend upwards of 10000 dollars to buy quality carbon and not cheap carbon. The thing about Scott sports compared to when I bought my Scott USA is that Scott has been bought by a Chinese company and I noticed that all the components like handlebars and seatpost and saddle are all syncros which is there own brand. Where have mavic and raceface and Easton disappeared to.
Another great video Reg which I have learned from Cheers. 👍 Luckily my Scott CR1 (2010) is fitted with external bearing bottom bracket which I don't believe is so bad? Keep these informative videos coming.
This is a real problem. In this day and age, this shouldn't even be an issue, but as its from a major manufacturer, they should recoup or repair at no expense to the customers. I've never seen the interest in carbon fibre bikes, they're like blue ray discs, completly unnecessary. We've got excellent aluminium bikes, lightweight, durable, reliable, and a lot cheaper.
You could try applying a little heat to the frame before pressing the BB out and the new one back in. I'm not sure that Scott frames are any worse than any of the other brands that all use crappy Chinese manufacuring.
Hello, could you please help about 2 bikes i have in my mind to buy.The first is a scott apsect 930 and the second one is a superior xc879.I dont know which one is better, i also dont know a lot about the superior brand.If you could help me i would appreciate it
Regi, seriously 2h - is that the first time you are replacing a bottom bracket?? All Shitmano plastik BB`s come out in million pieces 😅 That`s the standard these days and the everyday struggle in our bike workshops. Thanks to the marketing, influencers and everybody who wants to make bigger profits.
Normally they aren’t this bad! 😅 The “2 hours later” was for comic effect rather than being a accurate reflection of the time. 😘 But yes you speak the truth. 🙂👍🏻
I am just curious, will aluminum press fit button brackets frame have this issue also. Or it a defect in the manufacture process on carbon frame. Try making a puller it might work better I hate punching bearing out form frame. Sorry you mention you have a puller. Have you service these bb bearing or just replace them .
I’m planning to buy a new puller for this size bearings, I just need to get a reliable delivery. (Not easy in Brunei) The bearings were already damaged so no point to service them. It’s mostly an issue with carbon manufacturing Processes. It is a mould of the bottom bracket not cut like metal so the Tolerances always poorer. It can happen with metal bikes during welding… but it’s far less common.
Back in my time TITANIUM and CARBAN FIBER are toughest steel with out any complaints except for the price next to that is ALUMINUM, all this was in the late 80's. From your review about SCOTT BICYCLES it made me not to go for it especially using plastic for over $1,000.00, hey I'm going with TREK BICYCLES or SPECIALIST BICYCLES. And by seeing their ad's got me convinced that I should get a SCOTT BIKES 🚲 Thank you so much & hopefully people will see this.
Reginald , looking for help, i have the same BB issues, I'm just going o get a new bike for next season, recommend any mountain bikes between 1000-2000$? I usually take it and change the parts, id like to get a shimano 105 on a mountain bike and try it out top end speed lol. I replace my BB every 6 months, I might buy the same bike again if i can buy a titanium BB that fits or something like it.
Hi! If you have the same problem it can be fixed. Just ask your local bike shop to do the same as I did. 🙂👍🏻 I can’t recommend a new bike as I don’t do MTB, but I’d probably avoid carbon and my friend had a really good steel hard tail MTB that he loves. 🙂 All the best! Reg.
Look for BB86 with a threaded bottom bracket. This way you will be safe from thread damage over time nad have better alignment then the crappy threading by the manufacturers.
had a 2017 Pinarello Dogma F8 for 5 years full carbon bike and I did all my own maintenance. I never had one issue you mentioned with my bottom bracket. I was threaded BB so I think your blanket statement to avoid a carbon bike altogether is just biased and false.
It’s a generalised statement, but reflecting the raw data. On average carbon bikes are not only more prone to serious manufacturing defects like this but they also suffer more overall from damage and day to day use. So, you can argue “not all X is bad because… my personal experience.” But it’s not really an argument. It’s the same denial of reality and pattern recognition we see in the media. 🤷🏻♂️ PS. I’m very glad your bike is fine. 👍🏻
I'm glad you're not working on my bike. Basically, that's called an interference fit to keep things nice and tight! No one should be able to push a bottom bracket in by hand! By sanding down the BB shell, you've ruined that frame. Now the bottom bracket doesn't fit tightly; it has room to move and cause creaking. Also, if the bottom bracket bearings seize, those cups will spin in the frame! For the record, I've had two of the exact same models of this Scott Foil with zero bottom bracket issues. Align the cup and gently get it started by tapping it in with a mallet, make sure it's going in straight, and then get the BB press on it. Job sorted. If and when you are removing the BB and it's tough to get out, remove the bearing from the plastic BB shell first. This releases the pressure off the cups pressed into the frame. Once the metal bearing is out, the plastic cups come straight out with very little trouble.
You are correct that now I have removed the high spots in the shell (that wasn’t round) the BB cup fits in easily. (It’s not ideal but it’s better than the previous situation.) But that is why I have opted for a screw type BB system. This way it won’t move or make any sound. It can’t move because the threaded cups are screwed together tightly against the frame. If there was any possible risk of movement you could use a retaining compound. It’s been several years since I did this service and I’m happy to report the BB Is running smoothly with no complaints from the customer. 🙂👍🏻 Bearings can move freely now where as before there was so much side pressure from the shell that the crank didn’t spin! In fact the spindle was just grinding against the ID of the bearings as they were fixed in place. All this could have been prevented if the manufacturer had made the shell the correct size in the first place but unfortunately that is hard for them to do in carbon. I’m glad you don’t have a problem with your frames, however as a bike mechanic is see way more frames than you and unfortunately many are faulty. Even after the metal bearings came out the cups were still very tight, this is NOT NORMAL. Normally the shimano BB can be removed from a frame without smashing it to bits. That should indicate how bad this situation was.
Trust me, I have owned carbon, aluminium, aluminium mixed with carbon, steel and titanium. If I could only have 1, I’d choose Litespeed Titanium every time. 😁
@@reginaldscot165 I'm looking at getting a used litespeed. Some of the ones I'm finding in my area are from the 2000s. Would you recommend one of these or should I be looking for a newer model? Anything I should know or to look for in the older models?
@@al-du6lb Older is fine if it’s titanium it shouldn’t age. Just look out for cracks around welds and any dents. If the frame looks good, it probably is. Ask the owner to get it checked if you can. Just avoid the models that had carbon back triangles. Go for full titanium. 👍🏻
@@reginaldscot165 Never understood carbon triangles. One of the reasons I'm buying titanium is to avoid using a frame with weak areas. Now carbon seatposts are fine; if they break they can easily be replaced with no impact on the frame.
BB shells are almost always not perfectly round or accurate in length because most of the time they are molded, like you said. That's why Shimano make the cup in plastic so they can adapt to a non perfect shell. Token, Praxis Works and others also understood that the main point is not to complain about the not so well manufactured frames, but to find a solution to adapt.
The plastic BB doesn’t fix the problem (this video) more often than not it just hides it temporarily. The second part of your comment feels a bit like excepting poor quality products… if people stop complaining then there is zero incentive for manufacturers to improve. What we need is more people complaining or less people buying theses badly made carbon bikes. Like me ☺️ 😂
@@reginaldscot165 Are titanium bikes a little heavier than Carbon? I have a Kona road bike its a little heavy but I think the weight is perfect for the overall conditions here. I never owned a really light bike but it seems to me that in loose gravel or sand which is everywhere here a light bike would tend to give out from under and slide.
That is a problem in bonded BB shells, but not so much in press fit systems like this. But you are right, it’s 1 more reason why I don’t like carbon frames. 🤭
I did, but the thread is not supposed to hold the BB firmly together. The thread is an installation help and replaces your installation press. I have never seen a mechanic doing this, what makes you believe this will hold? Do you use special grease or glue and what torque? What is the manufacters opinion on these BB`s and how much torque are you allowed/able to apply? If you can drop a new PF BB in by hand, the frame is done - in my opinion (and it is likely to be a Trek or a Specialcrap)
every bike manufacturer goes through poor quality control from time to time - inform factory rep and machine true and if cannot return to the factory for replacement
That could work, but what do you suggest? Heat gun? Might damage the carbon? (Also don’t own one) Hair dryer? in the past I find applying heat quite difficult and dangerous. But if you have a good way to do it safely I’m very much open to suggestions! 🙂🙏🏻
@@reginaldscot165 I would stay away from a heat gun. Those are after all designed to take paint off for example. I use a cheap soldering heat gun. This will allow you to control the temperature. Between 60 and 80 deg should be safe. However a hair dryer will provide you with even more safety when it comes to overheating it. After all it's not designed to burn someone. Even 40-60 deg celsius will certainly make the resin a bit more giving. Another good idea is to soak it in some creeping fluid like WD40. Lubrication and some breaking of corrosive surface bounds (graphite on metal) won't hurt.
Only two brands are worth its money: LOOK and TIME, the rest frames are rubbish. Carbon fibre during the curing process (heating) changes its volume, so this has to be calculated by engineers a necessary additional material stretchng and /or expansion required. Experience brand shave no problem with this problem and quality control is tight.
Western brand fixation makes you overlook that fact that brand from the manufacturing country may those times provide far better quality for the money. LOOK TIME SCOTT SPECIALIZED - avoid them ALL. They are basically drop-shipping sellers.
Not as comfortable as steel forks. I’ve never tried titanium forks although I’d like to. Carbon is ok, as long as you check it regularly and it’s made by a manufacturer you trust. Also it’s best if it’s a tried and tested simple design, the newer ones with all the internal cables I don’t trust as much… (like the ones on the SL7 that keep snapping) Finally, if you are in a crash, replace it. I crashed a bike a few years ago, the fork looked fine but I still replaced it, it’s not worth the risk.
So you won’t buy a Scott. You made another video saying you won’t buy a Trek. You dislike carbon bikes in general, it seems. So, modern technology is out. 2 of the best and most respected cycling brands are out. It’s not hard to see you’re just trying to get likes and don’t really even like bikes.
If you believe that you will believe anything. 🤣 Also: Go on then, prove it! And: so you think the “best bikes” come with completely misshapen BB shells? 🤔
All Scott bikes are assembled at Giant factory in the Netherlands. I worked there for about 2 years and I saw most of Giant / Scott / Bergamont and in the past Trek were assembled the same way.

@@reginaldscot165 I see what you did there... I would really like an endurance style bike in titanium
This is why Cannondale and Trek have abandoned the crap (multiple) push-fit BB standards and gone back to threaded
True. Never had any problems with my press fit, however that’s into a 2.mm thick titanium shell. 😉

Aluminum in a carbon frame has other disadvantages: electrochemical corrosion from the two materials, different thermal expansion.

Don’t you mean 2 bad Scott bike frames? In 1 video… and I have seen more, just didn’t record it. 🙂
@@reginaldscot165 I work in engineering manufacture, and understand you get variability, thus in your job you will obviously see some bad cases over time too, you must handle many bikes daily. I know most carbon frames are made in China and shipped to Taiwan for finishing, as is our client currently. They are hand made so you are bound to get some come through bad. But in terms of actual ride and handling, I have found Scott to ride brilliantly, stiff, handles really well. No complaints, and as I said I love it. Like going out in a new sports car. I guess I've been lucky to have good builds. You call them plastic in your video, which is a bit unfair. Carbon is a very strong and very versatile material. I'm actually working on a McLaren carbon bike frame as we speak, a new hardtail in development, so am involved with it's design and build. I will raise the issue you brought up with the bottom bracket in your video with my colleagues for ref. However the Hardtail bottom bracket is quite a bit different to a road bike lol. In fact as an after thought, your video here ought to be sent to Scott so they can investigate the poor manufacture issue you've found.
What the hell was wrong with threaded bottom brackets and why did it have to die??
Because the manufacturer wanted to sell plastic bikes at a higher profit margin and threatened BBs didn’t work in plastic.
What bike WOULD you buy? I think you made some very good arguments for titanium in the past, but do you have a brand that you like?
I bought a Litespeed T1SL rim brake. 🙂
Couldn't the frame be sent back to Scott for a warranty replacement?
That depends on a long list of factors.
Hi Reginald, thanks for your video. I would be interested in buying a Scott Foil 10 2017 or a SuperSix Evo Hi MOD 2013, but after your video I'm a bit worried😆. Should the Cannondale be more mechanically appealing? It's also a 400 km bike, but the Foil is modern and aero...
Forget both! (Although the Evo is better) Aero frames make basically no difference. Wheels and body makes a massive difference. So if you are young and want to go fast buy stiff aluminium and save the rest of the money for better wheels and aero kit!
If you want a better all round bike, but steel or titanium. Forgot carbon, I’m 38 and I regret all the money I wasted on carbon frames. I should have just bought titanium to begin with. 😁👍🏻
@@reginaldscot165 Wow, I didn't expect this type of advise, especially in a world of carbon frames!! And also make me astonished know that aero frames do not make differences at all. I come from the '10 era of cycling, when I was 10 and race with bike was my sport, in this years I've lost some notions on new technologies.
For sure I will save up money for aero wheels, better if tested in wind gallery from brands who certificate that. Thanks for sharing us your experiences.
Could you ream out the bb. I own a Scott USA as they used be called and I have had no problems considering it’s an old Mtb and the lightest in it’s day. But looking at todays Scott website and others they have doubled in price and are loaded with thinks that are of no benefit to your average rider.
Metal can be reamed easily but normally it’s not needed on metal BBs. The problem with carbon if you try to ream it is it would grab or snag and probably do damage. Sanding is much easier.
Now from what I have seen over the last few years if you want carbon you will need to dig deep in your pockets and spend upwards of 10000 dollars to buy quality carbon and not cheap carbon. The thing about Scott sports compared to when I bought my Scott USA is that Scott has been bought by a Chinese company and I noticed that all the components like handlebars and seatpost and saddle are all syncros which is there own brand. Where have mavic and raceface and Easton disappeared to.
@@reginaldscot165 Here in Ireland a good hard tail Scott bike will cost 12500 euros and if you by a lesser bike they fit them with rubbish components.
Another great video Reg which I have learned from Cheers. 👍
Luckily my Scott CR1 (2010) is fitted with external bearing bottom bracket which I don't believe is so bad?
Keep these informative videos coming.
You are very welcome. 🙏🏻 Ride safe!
Wonder what the warranty is on this frame?
Good question
I had a solace 20 disc. Just purchaed the new Aero RC. 15k 2023. I want your opinion. Please.
SRAM RED Di2 Zip highest rim model
. Prefer Contential Grator Grip tires
You really Don’t want my opinion on your bike. 😅
Safe riding!
This is a real problem. In this day and age, this shouldn't even be an issue, but as its from a major manufacturer, they should recoup or repair at no expense to the customers. I've never seen the interest in carbon fibre bikes, they're like blue ray discs, completly unnecessary. We've got excellent aluminium bikes, lightweight, durable, reliable, and a lot cheaper.
Agreed! 🙂👍🏻
You could try applying a little heat to the frame before pressing the BB out and the new one back in. I'm not sure that Scott frames are any worse than any of the other brands that all use crappy Chinese manufacuring.
Yeah, all the big brands are much of a muchness. 🙂
Hello, could you please help about 2 bikes i have in my mind to buy.The first is a scott apsect 930 and the second one is a superior xc879.I dont know which one is better, i also dont know a lot about the superior brand.If you could help me i would appreciate it
I don’t buy any mainstream bikes and I don’t buy MTB so I can’t really give any advice.
If you were buying a road bike I could give some. 🙂👍🏻
I have Scott aspect 930
For last 3 years its going good I do good hardtail on it and roughly 5K per year
Regi, seriously 2h - is that the first time you are replacing a bottom bracket?? All Shitmano plastik BB`s come out in million pieces 😅
That`s the standard these days and the everyday struggle in our bike workshops. Thanks to the marketing, influencers and everybody who wants to make bigger profits.
Normally they aren’t this bad! 😅 The “2 hours later” was for comic effect rather than being a accurate reflection of the time. 😘
But yes you speak the truth. 🙂👍🏻
I am just curious, will aluminum press fit button brackets frame have this issue also. Or it a defect in the manufacture process on carbon frame. Try making a puller it might work better I hate punching bearing out form frame. Sorry you mention you have a puller. Have you service these bb bearing or just replace them .
I’m planning to buy a new puller for this size bearings, I just need to get a reliable delivery. (Not easy in Brunei)
The bearings were already damaged so no point to service them.
It’s mostly an issue with carbon manufacturing Processes. It is a mould of the bottom bracket not cut like metal so the Tolerances always poorer.
It can happen with metal bikes during welding… but it’s far less common.
Welding makes things warp too.
Back in my time TITANIUM and CARBAN FIBER are toughest steel with out any complaints except for the price next to that is ALUMINUM, all this was in the late 80's.
From your review about SCOTT BICYCLES it made me not to go for it especially using plastic for over $1,000.00, hey I'm going with TREK BICYCLES or SPECIALIST BICYCLES.
And by seeing their ad's got me convinced that I should get a SCOTT BIKES 🚲
Thank you so much & hopefully people will see this.
You are welcome. 👍🏻
Giant is butter
Reginald , looking for help, i have the same BB issues, I'm just going o get a new bike for next season, recommend any mountain bikes between 1000-2000$? I usually take it and change the parts, id like to get a shimano 105 on a mountain bike and try it out top end speed lol. I replace my BB every 6 months, I might buy the same bike again if i can buy a titanium BB that fits or something like it.
I was thinking maybe the specialized Chisel Comp if I go over budget
Hi! If you have the same problem it can be fixed. Just ask your local bike shop to do the same as I did. 🙂👍🏻
I can’t recommend a new bike as I don’t do MTB, but I’d probably avoid carbon and my friend had a really good steel hard tail MTB that he loves. 🙂
All the best!
Reg.
@@reginaldscot165 thanks for the reply :)
Look for BB86 with a threaded bottom bracket. This way you will be safe from thread damage over time nad have better alignment then the crappy threading by the manufacturers.
had a 2017 Pinarello Dogma F8 for 5 years full carbon bike and I did all my own maintenance. I never had one issue you mentioned with my bottom bracket. I was threaded BB so I think your blanket statement to avoid a carbon bike altogether is just biased and false.
It’s a generalised statement, but reflecting the raw data. On average carbon bikes are not only more prone to serious manufacturing defects like this but they also suffer more overall from damage and day to day use. So, you can argue “not all X is bad because… my personal experience.” But it’s not really an argument. It’s the same denial of reality and pattern recognition we see in the media. 🤷🏻♂️
PS. I’m very glad your bike is fine. 👍🏻
Why don't they just mold the CF onto a CNC'd inner steel sleeve ? Then cylindricity is guaranteed.
They could, but you still get problems with the bond between the metal and the carbon, and things move during the curing process.
This kind of molding isn't that problem free as you may think.
I'm glad you're not working on my bike. Basically, that's called an interference fit to keep things nice and tight! No one should be able to push a bottom bracket in by hand! By sanding down the BB shell, you've ruined that frame. Now the bottom bracket doesn't fit tightly; it has room to move and cause creaking. Also, if the bottom bracket bearings seize, those cups will spin in the frame!
For the record, I've had two of the exact same models of this Scott Foil with zero bottom bracket issues. Align the cup and gently get it started by tapping it in with a mallet, make sure it's going in straight, and then get the BB press on it. Job sorted.
If and when you are removing the BB and it's tough to get out, remove the bearing from the plastic BB shell first. This releases the pressure off the cups pressed into the frame. Once the metal bearing is out, the plastic cups come straight out with very little trouble.
You are correct that now I have removed the high spots in the shell (that wasn’t round) the BB cup fits in easily. (It’s not ideal but it’s better than the previous situation.) But that is why I have opted for a screw type BB system. This way it won’t move or make any sound. It can’t move because the threaded cups are screwed together tightly against the frame. If there was any possible risk of movement you could use a retaining compound. It’s been several years since I did this service and I’m happy to report the BB Is running smoothly with no complaints from the customer. 🙂👍🏻
Bearings can move freely now where as before there was so much side pressure from the shell that the crank didn’t spin! In fact the spindle was just grinding against the ID of the bearings as they were fixed in place.
All this could have been prevented if the manufacturer had made the shell the correct size in the first place but unfortunately that is hard for them to do in carbon.
I’m glad you don’t have a problem with your frames, however as a bike mechanic is see way more frames than you and unfortunately many are faulty. Even after the metal bearings came out the cups were still very tight, this is NOT NORMAL. Normally the shimano BB can be removed from a frame without smashing it to bits. That should indicate how bad this situation was.
Man, I would have tried to warranty the thing. Titanium is looking better and better all the time..
Trust me, I have owned carbon, aluminium, aluminium mixed with carbon, steel and titanium. If I could only have 1, I’d choose Litespeed Titanium every time. 😁
@@reginaldscot165 I'm looking at getting a used litespeed. Some of the ones I'm finding in my area are from the 2000s. Would you recommend one of these or should I be looking for a newer model? Anything I should know or to look for in the older models?
@@al-du6lb Older is fine if it’s titanium it shouldn’t age. Just look out for cracks around welds and any dents.
If the frame looks good, it probably is. Ask the owner to get it checked if you can.
Just avoid the models that had carbon back triangles. Go for full titanium. 👍🏻
@@reginaldscot165 Never understood carbon triangles. One of the reasons I'm buying titanium is to avoid using a frame with weak areas. Now carbon seatposts are fine; if they break they can easily be replaced with no impact on the frame.
Do you have the same experience with Colnago?
Honestly I can’t remember, not worked on many. But if they have a BB86 press fit into carbon then it’s likely they won’t be perfect. 🤷🏻♂️
Wow. Quality control is just disgraceful. I would ask for my money back. Really enjoyed your workmanship.
Thank you 🙏🏻
What would you buy then?
Good question. Take a look at some of my other videos, especially the one I did on “the worlds best performance road bike.” 😁
BB shells are almost always not perfectly round or accurate in length because most of the time they are molded, like you said. That's why Shimano make the cup in plastic so they can adapt to a non perfect shell. Token, Praxis Works and others also understood that the main point is not to complain about the not so well manufactured frames, but to find a solution to adapt.
The plastic BB doesn’t fix the problem (this video) more often than not it just hides it temporarily. The second part of your comment feels a bit like excepting poor quality products… if people stop complaining then there is zero incentive for manufacturers to improve. What we need is more people complaining or less people buying theses badly made carbon bikes.
Like me ☺️ 😂
Very informative, thanks !
You are welcome 🙏🏻
I see brand new bikes with BB pressed in dry way to often
All the time…
I'm actually impressed with Scot. Who else could paint a dog turd and make it look so nice.
Unfortunately I’m not a fan of their painting. 😂
what bike would you recommend in its place ? Similar to the same style.
I wouldn’t to be honest, I don’t buy carbon bikes. I like metal bikes, Particularly titanium. ❤️
@@reginaldscot165 What type of titanium bike brands do you like?
@@reginaldscot165 Are titanium bikes a little heavier than Carbon? I have a Kona road bike its a little heavy but I think the weight is perfect for the overall conditions here. I never owned a really light bike but it seems to me that in loose gravel or sand which is everywhere here a light bike would tend to give out from under and slide.

Hello regi.. between scoot addict 30, orbea m30 and giant tcr??
If you put a gun to my head TCR. But if I have a choice then non. Get a Ti or custom steel bike.
@@reginaldscot165 why a ti or steel??these companies got no quality carbon franes??
And if i go to Titanium.what choices??lynskey is good??
Generaly...a Aluminum BB should never be in a carbon Frame...al the alu Parts expand with temperatur...and Carbon didint!
see the proplem?
That is a problem in bonded BB shells, but not so much in press fit systems like this. But you are right, it’s 1 more reason why I don’t like carbon frames. 🤭
Everyone is using that tool... stop. BB tool is the best tool. And there are so many possibilities to use it without slamming on a bike...
Correct! Since that video I have more tools. 🙂👍🏻
WTF you just pushed a PF bracket in by hand? Don`t you know the shell will come loose and eat up the frame? Congrats...
Did you notice that it’s screwed together and doesn’t move?
I did, but the thread is not supposed to hold the BB firmly together. The thread is an installation help and replaces your installation press.
I have never seen a mechanic doing this, what makes you believe this will hold? Do you use special grease or glue and what torque? What is the manufacters opinion on these BB`s and how much torque are you allowed/able to apply?
If you can drop a new PF BB in by hand, the frame is done - in my opinion (and it is likely to be a Trek or a Specialcrap)
Its going to come loose for sure. There is a reason for that pedals and BSA BB`s are reverse threaded in one side.
Could you make a tools tour and what brand do you recommend 😄
Sure, I have a wheels video coming up next but I can do that tour after. 👍🏻
thanks for the explanation
You are welcome 🙏🏻
every bike manufacturer goes through poor quality control from time to time - inform factory rep and machine true and if cannot return to the factory for replacement
Especially carbon bikes…
Why don't you soften this crap up by applying some moderate heat?
That could work, but what do you suggest? Heat gun? Might damage the carbon? (Also don’t own one) Hair dryer? in the past I find applying heat quite difficult and dangerous. But if you have a good way to do it safely I’m very much open to suggestions! 🙂🙏🏻
@@reginaldscot165 I would stay away from a heat gun. Those are after all designed to take paint off for example. I use a cheap soldering heat gun. This will allow you to control the temperature. Between 60 and 80 deg should be safe. However a hair dryer will provide you with even more safety when it comes to overheating it. After all it's not designed to burn someone. Even 40-60 deg celsius will certainly make the resin a bit more giving. Another good idea is to soak it in some creeping fluid like WD40. Lubrication and some breaking of corrosive surface bounds (graphite on metal) won't hurt.
Doesnt work! Metal is exanding under Heat,,,,carbon dont
Only two brands are worth its money: LOOK and TIME, the rest frames are rubbish. Carbon fibre during the curing process (heating) changes its volume, so this has to be calculated by engineers a necessary additional material stretchng and /or expansion required. Experience brand shave no problem with this problem and quality control is tight.
Agreed, it’s just a lack of quality control and the fact people will still buy it even when it’s sub-standard.
Western brand fixation makes you overlook that fact that brand from the manufacturing country may those times provide far better quality for the money. LOOK TIME SCOTT SPECIALIZED - avoid them ALL. They are basically drop-shipping sellers.
@@rosomak8244 Bollox, Look & Time are the lick.
Press fit is niot practical at all specially on carbon frame
Press fit is the best, on metal frames. 🙂
My own carbon frame is very practical with press fit bottom bracket. I don't see the point in having to deal with damaged threads on it.
Send the frame to hambini
He would have done the same as me, except he would have fitted his own brand of BB. 😉

Well yes, but if I did that I can’t make like 14 other videos moaning about different brands of carbon bikes. 😉

Or aluminium, or titanium. 🤭
What's your opinion of carbon fiber forks?
Not as comfortable as steel forks. I’ve never tried titanium forks although I’d like to. Carbon is ok, as long as you check it regularly and it’s made by a manufacturer you trust. Also it’s best if it’s a tried and tested simple design, the newer ones with all the internal cables I don’t trust as much… (like the ones on the SL7 that keep snapping)
Finally, if you are in a crash, replace it. I crashed a bike a few years ago, the fork looked fine but I still replaced it, it’s not worth the risk.
