How Repairable Is A Carbon Mountain Bike?

How Repairable Is A Carbon Mountain Bike?

We often hear people say that they buy aluminium frames instead of carbon because they are scared of breaking them, but with the repairability of carbon compared to aluminium frames, there’s an argument that carbon could be the better option long term! Anna is at the Bristol Bike Repairs shop to run through repairing her damaged MTB frame and get an in-depth look at the carbon fibre repair process needed to get her bike back out on the trails!

    Carbon: "chain falls off, needs repair" , Aluminium: "chain falls off, get the crowbar, we need to get the chain out" :))



  2. Janny on October 5, 2022 at 2:45 am

    Carbons really pricey in ph though 😔



  3. Jo Gem on October 5, 2022 at 2:47 am

    I’m not convinced by that repair, seems like a high tech plaster/ band aid with some resin seeping into the crack, what about cracks that are deeper or almost totally cracked, why didn’t we see the finished article or get a rough estimate of cost. This video leaves more questions than answers.
    I’ll stick with alloy frames, I’ve ridden frames with small dents in the downtube and toptube, couldn’t do that with carbon.



  4. James on October 5, 2022 at 2:48 am

    This video just confirms WHY I don’t want carbon. I don’t want a super brittle bike that can crack without me noticing or break the frame because a chain came off. Carbon = overpriced trash 🗑️



  5. Mahen Naiker on October 5, 2022 at 2:48 am

    Interesting being Gmbn are there bike shops in South Africa 🇿🇦 that repairs carbon



  6. Neil Lowe on October 5, 2022 at 2:50 am

    I guess one question is what happens if you come to sell a frame on which has had a crack or a repair? Presume that even with a repair done, the frame would be worth significantly less, you’d have to declare it to the buyer and there is never any guarantee that the repair might last for years given that he only offers a 12 month warranty. At least with Aluminium, the frames are usually quite a bit cheaper to replace in their entirity and more easily recycled when damaged.



  7. MrSatchelpack on October 5, 2022 at 2:52 am

    Can anyone site an instance where a well done repair failed? The "crash it trash it" mentality has some validity, but maybe it’s a little too conservative especially for the crowd who cannot just drop another wad of cash on another frame. It would be cool if a youtuber did long term crack test.



  8. Sub for a Scooby snack on October 5, 2022 at 2:52 am

    tell you what, broken bones arent easily repairable as well as wallets



  9. Patryk Rusin on October 5, 2022 at 2:54 am

    I like this channel more than the rest of gmbn’s 🙃 love ya doddy



  10. Ola Normann on October 5, 2022 at 2:55 am

    can’t trust a carbon frame, its just dangerous if it breaks, life threatening



  11. Cheapsh0t247 on October 5, 2022 at 2:55 am

    Really interesting process and techniques, always great to learn about the products and the bike industry as a whole, please also pop to Argos bikes in Bristol and see what can be done with Steel, Alloy and Ti bikes in terms of repairs and refurbishments



  12. Pavan Vemuri on October 5, 2022 at 2:57 am

    Aluminum is cheaper and recyclable . That’s my main reason for switch



  13. John on October 5, 2022 at 2:58 am

    Personally, I avoid carbon frames 10% because every time a sharp rock bang hard into my frame I imagine it cracking oopen a carbon one, and 90% because I don’t think they’re worth the premium. Sure, if you’re racing (and serious about it), then by all means take every advantage you can. But for hobbyist riders just looking for fun and a healthy sport, I feel like it’s money thrown out of the window that could’ve went into better components. If money is not a problem, whatever suits you, but I think the hobby is already overly expensive to worry about grams on non-competitive riding.

    Hiya eveyone!

    We’re glad you’ve enjoyed watching the process’s involved with carbon fibre frame repairs.

    If anyone has anything they’d love to ask about carbon fibre repairs in general we’re happy to answer.

    Did you know we offer 12 months warranty with out repairs?

    This video was filmed in our brand new (not open to the public) premises, some of our equipment is yet to be brought over so we did what we could with the resources around us hence the process being simplified.

    We hope you all enjoy the video and if you like what you see we recommend checking out our social medias accounts.

    I don’t understand why people say aluminum is not repairable yes it requires that the frame be stress relieved after welding but that’s a specialized process that can be done way more places than carbon can be repaired.



  17. Paul J on October 5, 2022 at 3:00 am

    Could do that myself for £20. I’d never trust that.



  18. Pablo Briz on October 5, 2022 at 3:00 am

    In rowing it’s quite common to repair broken carbon oars and sometimes even hulls. Specially racing oars have to withstand an impressive amount of force, and if well repaired, difference (if any) is unnoticeable.



  19. Downhill 64 on October 5, 2022 at 3:00 am

    Yes like this video,



  20. György Mohl on October 5, 2022 at 3:01 am

    The point is, what makes the damage in the first place. A dropped chain, a flying pebble, or just the bike falling over most likely won’t damage an aluminum frame. Yes, you can repair carbon, but aluminum or steel doesn’t need repairing from small things.
    Still not convinced, i’d rather have a bit heavier and long lasting frame, than being afraid that an unnoticed damage can cause my bike break in half.



  21. Alf on October 5, 2022 at 3:03 am

    why would I get a frame that needs to be repaired every time it gets a little scratch



  22. James Aclao on October 5, 2022 at 3:03 am

    I buy aluminum because I can’t afford carbon 🤣



  23. brandon on October 5, 2022 at 3:05 am

    I would rather just stick to a metal frame and not be scared if my frame cracked after any crash. Specially when ‘fixing’ a carbon frame is just placing a bandaid over the crack.



  24. Jon Olav Lokken on October 5, 2022 at 3:06 am

    Honest guy, this repair man. He is very honest with you, Anna.



  25. Jack karnsky on October 5, 2022 at 3:09 am

    Carbon , when will you people learn !



  26. Floyd Blandston on October 5, 2022 at 3:13 am

    Have any of you dumazz’s not figured out that your magical CF isn’t just $$$ fibreglass?



  27. laeljon on October 5, 2022 at 3:14 am

    I have broken two aluminium frames… all my bikes are titanium now. Carbon just looks so worn after a few months….



  28. КИТАЙ ВЕЛИК on October 5, 2022 at 3:14 am

    Well, why didn’t they show what happened? ((



  29. Traveller Seko on October 5, 2022 at 3:16 am

    It is good to know it is repairable but I can’t trust any carbon frame repaired for downhill or enduro sessions. I’ve been riding aluminium frames for decades but I think I’ll go back to steal frames. There are boutique frame companies here in uk or anywhere in Europe but they are expensive at the moment for my budget. Best looking one is starling bikes sturn v2. For me it is top notch.



  30. J Brown on October 5, 2022 at 3:17 am

    I find it somewhat comical that she is holding a Canyon frame while talking about this. Currently I am waiting on a full refund from Canyon for a Spectral Mullet Frame that cracked at the shock mount around it’s 8th ride. Maybe it’s just luck but that never happened to me with Aluminum.



  31. Domonkos Czémán on October 5, 2022 at 3:18 am

    That is great. Although you should have mentioned the cost of the repair and the accessibility because for example, I could not find any shop like this in my country.



  32. Adrienne on October 5, 2022 at 3:19 am

    *<Investing in crypto now should be in every wise individuals list, in some months time you’ll be ecstatic with the decision you made today•>*



  33. Paul on October 5, 2022 at 3:20 am

    So yet again – don’t ride carbon 😂 How did this break happen? Terrifying.



  34. Juan Andrés Zenteno C on October 5, 2022 at 3:24 am

    How can he not say that the repair is stronger than before, but say that is as stronger than…?



  35. Gomer Pyle on October 5, 2022 at 3:25 am

    How much would a repair like this cost?



  36. fpeter01 on October 5, 2022 at 3:27 am

    It would be more interesting, if they would have used cute carbon repairer nanobots.



  37. EMILIEN790 on October 5, 2022 at 3:27 am

    My cracked frame been repaired once a couple years ago , repaired part still stiff and durable, I’m using my bike as usual with no limits. Good job



  38. Mr Jelly on October 5, 2022 at 3:27 am

    Really cool seeing how carbon is repaired to keep them going and seeing BBR at work. I want to get respray on my Stanton from them soon!
    Could you do similar content for other frame materials too?



  39. mhunt on October 5, 2022 at 3:29 am

    No carbon for me.



  40. Island Aerial on October 5, 2022 at 3:31 am

    I fix my ‘Lumi frame w/a bottle of nail polish 😂



  41. Kuba on October 5, 2022 at 3:31 am

    Sure carbon is repairable but at at the same time you can damage your frame by installing the mud guard the wrong way or overtightening a screw. I don’t mean to hate but for me mtb and having to look out for every tiny detail to not damage your frame don’t belong together.



  42. Alex on October 5, 2022 at 3:33 am

    Lots of great points, does it not require a post cure bake to get the best out of the resin? Also was it electric tape used for consolidation? Wouldn’t the stretch in that reduce strength and increase weight?



  43. Titter on October 5, 2022 at 3:33 am

    You can delaminate it without it being visible. On a mine hunting ship i was on in the navy made from glass fiber there was a regular service after x amount of years in use where there was a guy with a tiny hammer that checked every few centimeter of the ship by lightly tapping the hull with the hammer and if there was a hollow sound it was delaminated. Typically at the bottom of stairs and ladders and other areas that regularly got impacts was delaminated and needed to be repaired.



  44. Kaupo Raag on October 5, 2022 at 3:34 am

    The video was edited too short – we didn’t see the end result!!!



  45. Robb Chastain on October 5, 2022 at 3:35 am

    My deal is just that I need my bikes to work for me, not vice-versa. Upfront cost of carbon is more than I can afford, plus I don’t need the hassle of wondering if there is a crack in the frame that I can’t see. And no knock on those who embrace carbon, especially the racers on their bikes which can be disposed after being trashed in a spill in a corner or whatever.



  46. Andrei Wolffe on October 5, 2022 at 3:37 am

    It will all depend if you live somewhere with carbon repair experts close to you, because on some countries once you crack it, it’s goodbye.



  47. nvncblife on October 5, 2022 at 3:39 am

    Could you make a video about how we could decide between similar carbon fiber bikes from different brands? My guess is they all use the carbon fibers differently (eg the direction of the carbon fiber sheets); so how can we tell which are better quality or better in some aspects than others?

    Really good and interesting video, but alluminium can be mended – its called welding!
