Do you have a MTB suspension question for Fin? Put it below with the hashtag #AskGMBNTech for a chance to be featured on the suspension special! 👇
#AskGMBNTech What kind of trail do you reckon for suspension setup? Should I do several runs with one setup before changing anything? What to do about the increasing fatigue when you are doing run after run?
#AskGmbnTech im wondering, is it possible to have 2 shocks on the rear?
#AskGMBNTech Can you explain for a beginner, how the compression setting work? I find it hard to understand it and how to set it up right.
#AskGMBNTech Brilliant video both. Really enjoyable hearing two guys talking shop who are experts in their field. Lovely bike shed too. Could loose hours in there rummaging. My question is in regards to a 5th Element coil shock I’ve got on a 2002-2005 (I think) Santa Cruz Heckler 5 I bought yesterday. It’s my first dual suspension bike (finally getting back into biking after 12 years away)and the element has been TF Tuned previously. As a complete but wanting to learn amateur, how the heck do I set this thing up!? Are they any quick settings I can tweak or do I need specific tools to get a feel or is it just worth getting it looked properly. Thanks and all the best both!
Can you covert my 2020 Boxxer 200mm travel to coil.
please do a tour of the gmbn tech set
That would be rlly interesting
yeh that would be a good vid
@Andrew Dodd cool. thanks
This is a great video, Doddy! More thorough interviews with the unsung heroes of mtb like this please - you know most of them, surely!
I just purchased a Stanley Rotator Ratchet because of this video. I didn't know I needed one until today.
#askgmbntech Hi guys, big fan of the channel. Please give us a rundown of the mechanism behind a H/L compression and H/L rebound adjustment dials work. What actually happens inside the unit to change how it behaves? Thanks!
In most cases the fork is designed to act like a pump when it moves, moving a fixed volume of oil for every cm suspension travel (Though some designs probably tweak this as well).
This oil is routed through a restriction that slows the oil flow down. Turning the adjustment dial adjusts the size of the restriction either using a needle valve type setup or a pair of aligned holes that are misaligned from each other as the damping in increased, leaving a smaller and smaller overlapped area between the holes restricting the oil flow.
A one way valve is used so that the oil can easily go in the opposite direction to the flow when the fork moves the other direction, so compression damping only acts when the fork compresses and rebound only acts when the fork extends.
Low speed and high speed compression add a pressure sensing element to the system so on a sudden impact, the spike in the oil pressure will open a valve temporarily to allow the oil to take a different route. The most basic version of this is the way most forks will still move if you hit something really hard while they're locked out.
@Fred Gazeley check out the Dialed series on the Fox channel, they have a video where they tear apart a fork and show the valving and adjustments
@@milesmason3234 cheers mate!
Finn clearly knowes everything about bikes and suspension tuning, his t shirt confirmes that. (Kingdom brand tee)😁
This was undoubtedly the best video GMBN has done in quite some time! It's always nice to have an actual mechanic talking about the shop info vs someone that simply watched a video and then is presenting it. And for future, PLEASE give us more of this and more info on setting up suspension.
The man. The legend. Fin spends a significant amount of time repairing my screw ups! 😂
I like to call it creative spannering
I remember meeting finn when I worked at TF Tuned as a summer job while I was at uni in 2012. Super cool guy and his VW Camper wheel spins ALL THE TIME. I also used to use the lathe he now has when I worked at TF Tuned to make shock spacers, so it's nice to see its gone to a good home!
4:26 are those bike rim paper towel holder? 😂
That's funny. I have a broken enve m730 that I'll be making into shelf brackets too
I see he has some Wera tools. The Wera Zyclop is a great ratchet. Check it out! I've been thinking about sending Doddy one!
They do a Hammer Ratchet too
@Andrew Dodd Ha! No guess I kinda baited you with that one. I’m an elevator mechanic in NYC, and a fan of Wera Tools, and your show! That wera Zyclop is super cool.
When I saw your boy had some Wera stuff, I was surprised not to see one in his ratchet quiver.
Straight forward comments, humble in a lot ways.He knows his trade.Also years of hands work.
Really enjoyed this video, great to see this side of the MTB story, so many riding videos about, to see it from another perspective is great. Lovely workshop too
I would love more personal workshop tours!
Love this kind of stuff. More please!
That was great...always enjoy learning from a master. Thanks Mr Dodd. Be safe mate
Doddy this was my fave ever gmbn tech video. Absolutely absorbing from stat to finish. Let's see more of this guy. When he said his fave thing was his lathe I knew he was a guy I could relate to.
10 out of 10
Please do more of these type of vids with the interviews. It nice to see into what makes this sport so great.
Pulls out a $10 Aliexpress derailleur hanger tool: " oouuuhh, that is really posh".
That’s what I thought. He’s seen Park Tools stuff before and saw something different. It’s actually close to $25 now and take about 3 weeks to deliver. I would have the Park Tools one any day. Abbey tools make a green one with some similarities so it must work well. That Stanley tool is surprising
Park tools for every day.
The Aliexpress one is a complete copy of the Abbey tools one.
I got that because bikes like the Trek Rail have a particularly close gear hanger to the pivot.
Which my old Park tool doesn’t clear.
Thought I’d see if the cheap one did the job.
Yet to see how long it lasts in the workshop environment but it works pretty well
Please more of this workshop and this dude, absolutly owemose
One of your best videos Doddy. Love the workshop and tools. Fin seemed OK too. Love the other bits, how many of us have an r/c car or two in our bikecave?
Fin did a top job coil converting my Lyric. He’s right about how improved it is. Slippery slope though, now my previously lovely air shocks feel inferior and man-maths is rearing its head.
What's the bottom out like on big drops/hard compressions?
@@judechandler5102 zero problems. He left the valve in the top of the spring leg with the advice to put 3-5 psi in there if I was doing a day of massive drops. Tried it once and haven’t bothered since.
01:40 Thanks for caring sir!
Great show you got :)
Lovely shed! I like the raw OSB-walls you often see in sheds & local bike shops nowadays. It's a convenience thing for sure (so easy to build and afterwards you can hang an infinite number of things on 'em) but they also do provide that nice, warm touch, no?
I love what he said about the rear shocks. I agree, total air sucks. spings are needed in case of failure. if weight is a problem buy titanium springs.
Buying tools is as addictive as buying bike parts, I've spent thousands on snap on tools 😂
The most danagerous thing you can do is get one of their printed catalogues, and leave it in the smallest room of the house to browse whilst sitting on the throne... so many pages with corners turned over as 'the next thing I need'... lucky I can't order online direct, that would be a very expensive 10 minutes on the throne with my phone and the catalogue...
I just purchased a Stanley Rotator Ratchet because of this video. I didn't know I needed one until today.
Love this Doddy... I need more of this - 👌🏼
Love the wheel rim shelf brackets
Recently changed to new forks and have since installed ALL the volume spacers and will keep eyes on that stanchion o-ring and reduce where necessary, Fin has a good methodology there.
Another great Tech episode. I'm with Fin - I hate wrenching on dirty stuff!
Loved this video! I wish I had even half the knowledge Fin has and the gmbn guys. I started working on my own bike when the 1st lockdown started and have been learning bits but I feel way out of my depth due to having no one but videos to help. Although its a late comment, what would you guys or Fin advise or recommend I do when working on my own bike?
The black/blue Manitou is a Manitou 4. I had the same fork on my first proper MTB back in 1996
I like those shelf supports that he made out of sections of rim!!
What a ASMR video, lovely. Need more of this.
Love the GMBNTech Doddy. I was just left smiling🤪has my wife keeps telling I’m a weirdo by the love of tools, It’s there such a thing has too many tools?#AskGMBNTech by the way loved the rim shelf supports there, total Enginuity😜, one more thing what was that wheel with cable ties?WoW
Cool video, quite different. Good you guys are uploading on the daily. Still waiting for 4k though...
Wow just wow, a real mechanic
Wow, that was impressive and very interesting.
Great show, mate!
Such a good video thank you 🙏
Jagwire has a cable routing kit too I think.
Totally agree with the clean bike, always wash my bike and van before a service, turning up with a dirty bike is like turning up to the dentist without brushing your teeth first, not cool.
Coil for life. To have this level of knowledge would be so awesome ha. Experience.
One of your best videos.
Really love the video 👏🏻👏🏻👏🏻
Clean bike before taking it to the work shop. Is something iv done my hole life it goes for car's and motorcycle's as well mechanic's will love you for it.
Would be like going to the dentist without brushing my teeth
Hi Doddy. Love the tech videos. I recently bought a Polygon Trid ZZ slopestyle bike but I can't find any suspension set-up guides for it. Any suggestions on how to set up ss suspension. Thanks. Dylan. Also, I'm 145 lbs (66 kg).
What a top bloke.
Thank you for your always fantastic films. I learned again today.
Please do not get me wrong. What does Fin recommend when securing bicycles in the work stand?
I was always told not on a retractable seat post.
What do I do with carbon frames?
I would appreciate a contribution with your recommendations for all of these questions.
Cheers Manuel
A good and well maintained workstand such as a Kestrel, won't damage it. If I'm hauling on a BB or something, I'll change the seatpost over for a regular alloy one.
@@finlaypaton7202 Thanks for your respons. Keep it up and stay healthy.
love this type of stuff
ta
Those shelves! Godamn! If anyone has spare enves laying around I'll take them no need to cut them up 😂😂😂
Cheap Chineesium rims - posh stickers - shhhh, don't tell
Sampi fries on the wall ,awesome
The pump is from the Mach21! Haven’t seen this thing for a long long time🙃
You mean the Mag21? The Rockshox fork?
I enjoyed this show very much
#AskGMBNTech do the new ‘progressive Spring’ coil shocks work as well, or at all, on a frame specifically designed for an air shock? Big fan of the show, making lockdown bearable! Thanks
Only good friends let friends rummage through their tool boxes. 👍🏻
So much info for one vid, I need a cup of tea!
Love this
I've known Fin a while (since before I had a 1x8 chameleon ;) ), and use his knowledge and inventory even though I'm now in the south of France. The B word might change things but my one stop shop for techie stuff. Even daft questions about lathes...
and broken mugs :)
@@finlaypaton7202 {ROFL emoji}
fin on gmbn tech lets go undoubtably the best technician around id choose him over anyone he repairs my sons bike
Thanks Nick 🙂
Did the ask special with Fin get made? Would love to watch it
I wish we have this kind of bike mechanics in the phillippines
Same, cuz all bike mechanics here in the Philippines are too primitive, we call them "siraniko"
Great vid.
What is it with VW freaks, mountain bikes and tool fetishes! I always thought I was unique? 😂😂
By the end of the video, I felt like a 3 year old and wanted to ask him to be my best friend 😂
Hi great video does anyone know what backpack doddy is wearing?
I like how had his set up i need fox34 float 2016 model need a service never had a service since 2017 you know were to send it to please thank you doddy
Great vid
Fin is so right about E-Bikes
Thanks for the great video! #AskGMBNTech can I use Motul fork 20wd oil instead of Fox 20wt. Gold Bath Oil? Here in Brazil it is really difficult to find these Fox oils. Thanks!
Yes - add some Float Fluid to thicken a 15wt oil would be my preferred lubricant, If I can't get hold of the specific stuff.
Reminds me, I need to collect my shock from Fin.
clean your bike before you work on it. words of wisdom. cool workshop!
Time pedals. Awesome.
Heaven on earth. Who makes the schematics prints? Cheers
Ripe Digital printed them for me, I have some Evil ones left on the website
Finlay Paton ty my man I need to check those out 👀 sick stuff 👌
Did Fin used to work at Bonthrone Bikes as a manager?
Yes - many Eons ago
@@finlaypaton7202 Hi Fin I thought you looked familiar. I used to work there for a bit when you were the Vauxhall manager. It was around the time Steve Peat visited the store. You were a cool boss :)
@@smtkelly Thanks
#AskGMBNTech I’m planning of racing enduro this year on my Santa Cruz V3 5010 with a 150mm fox 36. The fork made a big difference and I was wondering if a coil shock would it make my bike more capable and give me the grip I’ll need in those steep Welsh woods?
Really interesting vid - never considered a coil - hmm the brain whirring now!
#askGMBNtech I have a Kona Process 153 from 2015 and love riding it. My son has a coil shock on his Specialized SX Trail and I love the way that rides. I have a rockshox monarch shock on the Kona but would love to fit a coil shock but is this like to blow through the travel as the frame is design for air?
Hey thanks for another great video! #askgmbntech Why is there no video online about servicing a fox transfer (2017-2020) dropper post? Will you make one? Including hacks on the many expansive tools? Cheers
Look on Fox's Tech pages - you need lots of special tools - you can do without 2 of them if you are clever, but it takes longer, you definitely need the filler tool and the tool that holds the valve open. The tools are priced I think to make it really not worth the home mechanic owning them, which I think is a real shame.
@@finlaypaton7202 Hey thanks for the reply! did you give it a go? Love taking cae of my bike. Service/rebuild my Fox transfer seatpost is my next ambition and wouldnt mind spend a few (100?-200?) bucks on it. But spending about $1000 on specialist tools is in over my head. Real shame indeed!
#ASKGMBNTECH Thank you very much for the show really like it and learnt a lot. Those are my couple of questions.
1- How to really adjust the bushings on the fork when you replace them?
2- Whats is the best way to learn valving?
Thanks Regards, from Spain!!!
1 - The Bushes are pressed into the lower and held in place with a retaining compound, Within the legs of the fork they are tapered so you can adjust the fit of the bushes to the upper by moving the bushes a few mm up or down, basically.
2 - By talking to other suspension techs and experimenting with different shims stacks & tunes
@@finlaypaton7202 Cool Thanks!!!
I think I have a problem with bike mechanics and parts, I love tinkering with my bike and putting new parts on 😂
Very cool and a VW man to 👍🏻👌🏻
#AskGMBNtech Hello I always wondered why the Marzocchi dirt jumpers and dirt jam forks from the early 2000s had a nasty clonk when they rebounded, they worked fine when they got of the shelf but after the first time you took it apart they started clonking, I tried all kinds of thickness of oil but they never got as they where, I've lately been investigated the matter and realized that they have no valves for the oil just a big hole thru the piston so how did it even work fine from the start? Am I the only one why had this problem back then? Thanks for a great show!
Because they were filled with thick grease which will have coated all of the metal parts in the fork, then as soon as that mixed with the oil it looses anything to stop metal to metal contact, you can slow them down but it involves shutting off the holes and re-drilling.
Is that a Following v3? Or the new Offering? Ok 120mm then Following v3, I’m going to get one of these in the Summer.
Following V3, increased the travel a whole 4mm fitting a coil, LOL
That Stanley ratchet 🤯
There's more Internal Cable Guiders on the market. Elvedes has one for sure
#AskGMBNTech Is it okay, and if so, when and where, to do a shortcut/bodge in a suspension/dropper maintenance job task, where the proper and official way would be to use an expensive speciality tool that is only a one hit wonder. I'm talking fancy measuring tools, piston seal funnels, suspension shaft/ damper removal tools, seal setters, soft jaws, weird thread interface just to push or pull something, pressurized gas interfaces etc.
My suspension Q. What is the optimum way to set up a coil for varying rider weights and skill levels. We should all know how to tune an air shock, but what about a coil shock for small, incremental changes?
First and foremost get the spring rate correct
Once you have that.
Then you can fine tune damping & preload.
Yes boys
#askgmbntech I'm thinking about trying out a coil conversion on my 2021 Nukeproof Reactor 290. I remember Doddy did something similar. What would your tips be in terms of set up / buying, and what differences/benefits might I get?
Talk to your local suspension tuner - take his or her advice
#askgmbntech - I’d love to know Fin & Doddy’s thoughts on Sprindex coils. (Good product to dial in spring rate?)
Good if you are doing things like regularly carrying a heavy back pack, but pretty pointless otherwise.
Several manufacturers now spec their springs in the exact poundage, or you could just look at a selection of springs on a dyno, to get the one for you. The spring rates can vary up to 10% on some makes - even the really expensive ones.......
Hey Doddy, loving the content. Most of these I have used at one time or another apart from the epoxy one but it makes sense. I am currently trying to rebuild a 1998 Santa Cruz heckler and am looking for some advice on which forks to run. I was running them with an old set of RST delta TL however they have seen their best. I haven't ridden in a while and am gonna try and get back to a bit of XC, free ride, and maybe some enduro. I have a cane creek DB air for the rear but looking for the best 1 1/8 steerer 26" wheel based fork and at least 100mm travel. Thanks mate. #AskGMBNTeck
good luck with that! Not much out there that's new. Some of the old oil bath coil Marzocchi forks are excellent for their age, but don't compare with modern forks. finding decent straight steerer forks is really hard now. I wouldn't push your luck with any hard riding enduro or freeride on a 98 bike. Alloy from that era is notoriously brittle. The head tubes are short on the heckler, so buying second hand shouldn't be an issue. You could try the Rockshox Reba RL, but they won't really stand up to cane creek you have for the rear.
@@judechandler5102 Hey Jude, thanks. I am aware that I am limited in what I can get, I pushed the bike super hard when I used it regularly before and haven't had any issues. Santa Cruz were actually renowned at the time for the quality of aluminium they were using so am not too worried about the frame. I didn't think I would get anything near the cane creek and the only reason I got it was it was going cheap. The main thing I am looking for is the best of the options that are there knowing that modern tech will wipe the floor with it.
@@davehendry2519 Definitely try rockshox then. Fox and other higher end companies don't do straight steerer forks any more. Would highly recommend Reba RL forks at 100mm travel. Nice and light but still with acceptable performance and actually not that costly
#AskGMBNTech Hey I own a Fox 34 Rhythm fork model year 2020. I recently went out for a ride on a pretty snowy and muddy day. It was also cold so dirt and ice froze to my fork stanchions. I cleaned them a few times while riding. Before and during the ride my fork worked fine with no problems whatsoever. After cleaning my bike I wanted to put suspension oil on the stanchions and compress the fork a few times to lubricate and clean the seals. Doing that I realized that my fork wasn't working properly anymore. It's extremely stiff and I cant really compress it anymore even when compression and rebound are fully open. I can only do that when I let all the air out. But even then the fork makes a weird sound like metal is rubbing against metal or something. Also when I compress the fork completely with all the air out there is a constant whiz of air coming out between the stanchion and the top seal of the fork. Can a simple lower leg service fix this problem or is there a possibility that something major could be wrong with the fork such as a blown damper or a broken negative air chamber or something. I also checked if the fork isn't bent and to me it looked like this isn't the case.
You can buy a marzocchi Z2 or Z1 for less than the fox it's the same internals as the Rhythm. Fox rhythm is the lowest line of forks anyway a new 34 would only be about four hundred bucks. The amount of money to repair your existing Forks wouldn't be worth it.
Save the lower legs the air cap the compression cap and the rebound cap. Throw the rest away get yourself a new fork and take a bit more precaution when going out in snow or rain.
sounds like soemthing is stuck in the fork seals
The fork came with my bike and I know that it is the lowest of the Fox fork models. I sent an email to the Fox support but they wanted me to send the fork to them and I now wait for the price offering for the service. Maybe I need to learn how to do a lower leg service to find out if something is stuck in the seals or something because the service will be pricey for sure and might not be worth it. A new fork is much money to spend so I'll have to think about it a bit.
#askgmbntech coil forks. Please enlighten me on how to set them up, since they come with virtually every new entry-level MTB-at least where I’m from: the Philippines.
Specifically the sag and preload-are these related in any way?
Depends on the model - but yes Sag & preload are related if you preload the spring it will sag less. You may need to change your spring to get the correct sag point.
Insane
+1 for Time ATAC pedals for trail work (flats for jump sessions), run time on all my bikes for 20+ years. but they have recently dropped the quality level on very latest ones, so 'time' will tell.
And no service kits available fir the mechanism, unlike v similar crank bros.
The customer support is ace from Extra UK, just send them back
#AskGMBNTech hey, thanks for the opportunity. so, i was wondering if a suspension pro would advise a "normal" bike rider/mechanic to service suspension units (in terms of difficulty and needed knowledge). thanks. love the show. all the best from austria
Start with easy stuff such as a fork lower service
#AskGMBNTech I am interested in putting a coil shock onto my 17 enduro. How do I pick the correct spring for my riding style. Thanks for the excellent content!
You need to do a spring calculation, plenty of those on line.
You’ll need your weight - in your riding kit, the rear wheel travel and the shock stroke. Be sure to round up to the closest spring value. and Enduros tend to be very high leverage so add 50lbs to the calc.
That scooby powered T25 is the bizz... Was it AWD?
Rwd :)
@@finlaypaton7202Had an FSTI knocking out 330ponies AWD and she could get giddy in the wet, That T25 musta been great craic on twisty roads, pure giddy all the time... steer from the rear 😂
@@garrymc4563 Like a drunk Hippo on badly fitting roller skates, but it was fun
#askGMBNTech I have an 2017 Orbea Occam AM H30 (so alloy), I want a coil shock and I have concerns about the spring hitting the frame. Am I right to be concerned, can I fit a coil. hock to my bike? Was looking at something like the CaneCreek inline coil.
easiest way is to take it to your local suspension tuner, they will be able to check clearance
Quite often if you look at the other bikes in a particular model range, they will have a coil fitted.
