- View Description for more details. Carbon fiber bike frame repair for around $5. THUMBS UP if this was helpful in any small way: ) This video shows how I repaired the broken water bottle holder on my Specialized S-Works Tarmac carbon frame. Total work time involved? Around 1 hour. Most of the time will be spent sanding. I bought a kit on ebay for $30 for a previous repair several months ago. There was plenty of carbon and epoxy remaining so I was able to do this repair for only a few dollars in supplies.

In many cases, a broken carbon frame is repairable. My cracked carbon road bike frame had a soft spot in the top tube that flexed when pressed. Clearly it had been dinged by a previous owner. It seemed like a perfect candidate to undergo a do it yourself carbon frame repair.
I bought a carbon fiber repair kit on ebay that consisted of a roll of carbon fiber cloth, epoxy, hardener, and instructions. The kit was $30 with free shipping. There are many such kits available, so just search for one.
Some carbon repair shops specialize in repairing and refinishing carbon frames. But based on the pricing I’ve seen, a professional repair on my cracked Specialized S-Works frame would cost over $400. That’s too much for me. Plus, I wanted to see how easy it would be to complete a DIY repair.
Some pro shops claim that nearly every carbon fiber frame can be repaired no matter how severe the damage. Even if the tubes are broken. And that repairs are stronger than the original bike, with no measurable additional weight, and don’t alter the bike’s ride. My frame was cracked, which is not all that severe, so I can’t say from personal experience. If I have any cracked or broken frames in the future, I will definitely be performing the repair myself. Overall I thought it was very quick and easy. The most time consuming part was sanding down the new epoxy.
It’s possible to repair:
Cracked Tubes
Separated/Missing Tubes
Tube Replacement
Dropout Replacement
Car and roof rack accidents
Water bottle mount add-on
Handlebars
Seat posts
Carbon rims
Seat masts / topper
This video was about a carbon fiber layup repair, not paint. I did not paint the repair. My understanding is that a raw finish is just as durable as a painted repair, and won’t scratch and chip like paint would. Raw finishes require no maintenance.

For anyone watching this video in the future and is tempted to repair a broken frame, for the love of god DO NOT use paint thinner on a carbon frame. You will cause delamination
I was going to say something, but then I saw the date of the video. I'm a professional composite tech of 20 years and I'll admit that you actually did a decent job for someone making it up on the spot. If you're doing this again use acetone 👍
@@dontbelieveeverythingyouth8173 I am considering doing a diy repair of a crack on the lower portion of the downtube of my carbon mtb. Are you able to point me to any resources to help me performed this repair properly?
@@jakeb1778 EZComposites here on YT have got a great online store with some of the best materials on the market, they also have great instructional tutorials. I would start there.
@@dontbelieveeverythingyouth8173 thank you
agreed 👍
why apply carbon? it's not weakened. just clean off the epoxy with acetone and a heatgun and glue in a new rivet
Absolutely...
Hahaha.. Absolutely, just epoxy a threaded rivet in.
There was a dent
Thanks for posting the video! Got me trying to fix an old alu frame with a cracked chainstay that was weakened from a few chainsuck events and years of pedaling. A few comments based on my noob experience.
1. The frame in question suffered a hole from the chain impacts. I filled that with "ding stick" marine putty and sanded it down to provide a flat surface for the carbon cloth to rest on
2. The repair kit you mention has four times or more the material needed for a one time repair, so:
2. For practice, I got a short PVC pipe the diameter of the chainstay and did a couple of trial runs before working on the actual subject matter. These pipes are sold at the hardware store for a couple of bucks each and by chance come in diameters similar to the various frame tubes found on a bike
3. I decided to wrap several layers around the chainstay. I ended up applying three to five layers three times, for extra strength. Each time, I glued a thin starter strip of cloth to the chainstay, to act as an anchor to allow me to tighten the cloth down while wrapping it around the chainstay tube. I used contact cement for anchoring, which does not set on the cloth but easily bonds strong enough to keep the cloth in place
4. I used a smaller brush - I believe in the video you end up applying considerably more epoxy than needed
5. Glad I did the trial runs on the PVC pipe - as charming as it is, I found the parchment paper with masking tape method ineffective. When unwrapped, the surface looked crumbled just like shown in the video. Instead, I settled on applying two layers of electric tape. First layer basically in place of the parchment paper to cover the messy epoxy, the second to tighten things down. Electric tape is flexible and strong and comes off the cured epoxy clean an easy. As an extra, it works much better wrapping in tight spaces and small diameters if needed
6. The above netted a clean uniform finish with the classic carbon weave pattern visible on the surface. No sanding needed.
Hope this helps!
Excellent. Thanks for the great tips.
lol
I like this guy Martin from the tour the plant great , I have seen many of guys do a how to and they make it so complicated and you never under stand the procedure properly Martin get it done and it came out good I saw him riding the bike in another video
You probably put down more carbon than the bike had in the first place! Try 2 layers with the underlying layer cut atleast 10mm smaller to give an over lap which will give a better bond too.
Also, please tape up the edges of your repair area! It just makes it so much neater😄
Try using cling film if you don't want to buy peel ply. As you wrap around the wet carbon, pull the cling film tight to help bonding and squeeze out some of the air. Also whilst we're talking about air; if you whip up your resin like that when you're mixing it, you'll get air bubbles in the resin, causing lots of small voids when it goes hard and therefore really weakens your repair.
Lots of other tricks of the trade and following the other comments advice needed to make a better repair! But good effort for giving it a go. It will still more or less work the way you did it!
Thanks for the tips.
Great job 👍
Using things from the house and the repair kit. Excellent.
well, after watching this video i did indeed try this for myself, but it cost me 25 pound for the kit (available from a well known auction site), it is not quite as easy as it looks but it really did the job very well, consider that priming and painting and clear coating and wet sanding and then clear coating again took almost 20 hours for the whole bike frame, the carbon fixing was solved in about 2 hours including the sanding of the excess epoxy and carbon, job well done.
I used a double full wrap of carbon at opposite directions and baking paper to protect the epoxy and taped over with electrical tape to create the tightness needed, my old TREK 5200 UPS frame is back in business.
For all of those peoples saying you need to be an engineer, i am and basic understanding of materials is required and safety gear is needed because the fumes are very bad, much worse than fiber glassing
+tk380514 should mention that i weigh 95kg and the break was at the rear of the crank on the right hand side, crack and hole was in total enough to get my whole index finger inside, have ridden 1000km on it so far and the stiffness has not been affected at all, still an amazing frame, better than my other carbon framed bikes
tk380514 ..db np
So You still alive or did it crack again and you got killed lol
He diedededededed
@@SKBKER Still updating playlists so I doubt he kicked the bucket. Doubt the bike is still rolling though.
Great video! I'm glad to see you wrapped up the repair area this time around! Good use of parchment paper.
Turned out great!
Fantastic tutorial. I've carried out several similar projects, but one thing I'd like to correct about your tutorial is the fact that the repair should surround the damaged tube, to reinforce it as opposed ti just putting the carbon fiber on the crack itself.
Danial Arif Yes, i agree that would be stronger. As it is tho, the patch is holding up fine. : )
Thanks for sharing your thoughts and ideas...
This is really good info cause I recently broke a carbon bike that I found free abandoned at the park.
So you stole a bike.
And then broke the stolen bike.
@@ThiLI0n wrong. Someone abandoned it at a park and I took it.
@@Jamarkus_Delvonte yep, legally you had to turn it in. Withholding it is theft.
@@ThiLI0n I'll sell it
PROPER WAY: prep/sand your frame area, epoxy/lay first layer. let cure/dry 24hours. 2: sand/reprep area. lay epoxy and second patch. cure 24hours. 3: sand/prep area. paint epoxy on, lay third patch, allow 24hour cure. let whole mess cure afew more days then pretty it up. TIPS: DO NOT FAST STIR EPOXY, this creates air bubbles, which creates weak spots. stir epoxy slowly/thoughly.
Soak the CF patch before, then you'll be sure no air bubble are trapped and the CF is well bond to the frame. To compress all the layer while they cure, use an old inner tube and wrap it around very tight, you'll get better result.
Thanks for the tip.
When you say soak the CF patch, are you soaking it in water? Or apoxy?
Now I will try and be as nice as possible . You cocked up . There lots of holes in that finish which means you didn't compress the material enough . You need to tightly wrap the material completely and to help the bond strength (and speed) put near a heater . The other problem is you put too much resin on the carbon .Use a little less . Lastly you included the stitched part of the material . That is there to stop the material from fraying and coming apart .
Well done,thanks ( also 4 the less popular info u collected and share !!)
Oh and the white stitching on edge if carbon twill is not part of the lay up its stitching to stop fraying and should be not in lay up ! And oh dear with the wrapping ,love his enthusiasm but please don't try this at home 😉😜🚲
Good as new. Ready for the Tour de France!
Yes, this already won the Paris Roubaix. Next stop, TDF!!!
You can get better compaction and a tighter better bond by using something to wrap it that can apply more pressure. Maybe try plastic cellophane to wrap since you can cinch it tighter and tighter as you wrap
+racinjetford electrical tape pulled over created the tension and tightness needed
Hey great video! I have a question, I'm wanting to hand sand my carbon bike just for a new paint job. But I'm not wanting to mess up the carbon. What grit sandpaper do you think I should use?
With my frame the paint was pretty thick. I used around a 250 on the electric sander, then 400 dry sand, and 400 wet sand.
Le Tour de Plants ok great thanks!
Hey, what was the sander you used? I would like to purchase one
I bought it at Harbor Freight Tools. Their stuff is cheap and kinda poorly made, but for something with light use in mind, it can be okay. I think I got it on sale for $20. Reg price is 40 goo.gl/jQRP2f
Way,Way, more surface area than what is needed...Why didnt U bevel the hole and actually repair the hole before a coverup layer??? Looks like a patch
I had the same problem with my Collage C40 many years ago, my local bike shop carefully riveted a slightly oversized jack nut and applied some epoxy just to make sure. Problem solved.So the only problem (if it was), my bottle cage used two different size of fastening screws.
colnago
hello sir will a cling wrap (the one used in kitchens) can also be used as a substitute forr the parchment paper? or a simple tape/masking tape can also be a substitute for the parchment paper?
parchment paper is better. The plastic wrap and tape will stick to the epoxy.
Hi, thanks for the video! When I was watching it I thought - where could this damage come from in the first place. And then I took out a seatpost out of my new Fuji SLM 2.1 where I never used a bottle holder, and the placeholders for the bottle bolts underneath the seatpost were literally hammered in! You can see huge slices of carbon coming off where they hammered them in! Could you tell me if this kind of damage compromises a carbon frame reliability?
I think that modern frames are pretty strong and reliable and are made to have holes drilled in them.
@@LeTourDePlants but not hammered
tq..very helpfull..
Next time cut your carbon mat on a bias & into diamonds. also wet out the carbon before lay-up.
For wrapping, the parchment/waxed paper is fine but wrap with an old rim strip or innertube. That'll squeeze excess epoxy from your lay-up
Sweet. Thanks for the good ideas.
Hi! I am an aircraft desingner and builder, I use composit for many parts, you'r seam to be a honest Guy but if you do your home work and lear the right way to do that you Will be freaking out. Good luck !..
i have a 2010 gt zaskar carbon team and it looks like my chain stay has some fiber sticking out, but i don't know if it is the chain stay protector. do u think i should do the repair myself. but do you have to put the carbon in the same pattern
+zakka iwas I would totally do the repair myself, but I'm an avid DIYer. Anyway, I think the chainstay is a perfect location to wrap the carbon around a couple times just as a reinforcement! Good luck.
+Le Tour de Plants thanks for the help.
the kit you brought from ebay how much oz of resin and hardener does it come with? i brought a mixing container with a measure scale since i dont have a weighted scale should be okay right??
It came with several ounces of epoxy resin and hardener. I would use a liberal amount on your cracked seat stay. And you're using carbon fiber fabric too, right? I would also wrap the mended area after applying the epoxy. The wax paper with masking tape worked pretty well. Good luck.
Yes I'm using carbon fiber. ...I feel like the bottle I brought is the same exactly as yours in size they said it is 4 oz resin and 2 oz hardener for the bottle ...do u think that is correct or the bottle you have holds more than that?
While painting on the resin, I was thinking would it have been better to have cut the carbon to smaller pieces (1/2" X 3" long)
I have since learned that my patch was way too big for this repair.
Hmmm ,I am thinking that kit would be good for making home made carbon handle scales for knives.
hi , is it possible to sand off the decals on a bike like this? would that ruin the strength of the bike? I notice when you sanded you took of the decal layer but did not get as far as the carbon, so maybe it would be o.k. with very light sanding?
rainbowsalads Yes, there is quite a bit of paint on top of the decals on this bike. It would prob take around 4 hours to sand it down with a power sander, but it is possible. It would cut a lot of weight too. Maybe 100-200 grams.
thanks : )
So it means its even more comfortable using an allux (aluminum ) frame than the carbon frame ......
Carbon repair kit Belinya dimana bro mksih
"working man's" bike. Love it! Brilliant!!
Am wondering if or how many bikes u've built, from ground up Le Tour de Plants ? Would seem to be your niche, especially seeing how u could "make it fit" so to speak, should u run into any snafu's.....etc.
Am also wondering what do u do with these "repairs" of yours (that u've bought....) sell them? Keep them? Do u have "a large stable" of bikes (for sale) ???
al karg I've built up 5 or 6 bikes from the ground up, but would not call myself an expert. That's part of the reason I make these videos -- to show that you don't have to be an expert to work on your bike! This particular bike started as a bare frame that had two cracks in it. I found it on ebay for around $250, which I thought was a great price for a S-Works Tarmac (even with the crack). It has worked out very well as I have learned to love this frrame. The fit of the bike is excellent for me and it's reasonably light considering it's 9 years old. Cheers.
Hi is parchment paper the same as what we call greaseproof paper in the UK
Cheers Evan
i am unfamiliar with greeseproof paper, so cannot say for sure.
rather curious as to why you didn't allow the epoxy to dry before applying the next layer of fibre mat or why you didn't remove the cabling before you began the epoxy layering
Those things were not necessary in this case since it was a rather basic, minor repair. I didn't want to remove the cables because 1) it wasn't necessary, and 2) I didn't have new cables at that time so would have had to order some before completing the repair. Just wanted to see if it was possible without removing the cables, which turned out to be true.
makes sense. Thank you :)
I'm really tempted to sand down my frame to do a custom paint job. Do you have any advice for doing this?
+Stephen Hubbard Sanding the whole frame would be a lot of work. Be prepared for several hours. I would start with a handheld power sander then switch to wet sanding by hand with a wet sponge behind the paper to hold the contour of the frame. Good luck.
if you used a chemical paint remover it would cut out a lot of time. however it may not be safe to use on carbon fiber, it shouldn't be hard to find if it is.
Sean Klimczak Yes, it's worth a try. I tried paint remover on a different frame and it didn't work very well. Just kind of crinkled up and I still had to sand it, but it could have been due to the brand of remover I used or my procedures. It's worth trying again. I've been thinking about stripping and repainting this frame....hmmm.
I don't understand do you mix the blue and clear half and half???? Please help I bought this kit too
no not half and half. it may differ depending on the epoxy you've got. did you get instructions too?
Seems to have worked out pretty nicely but I think I would have pre-soaked the fiber instead of laying it dry and also would have wrapped it tightly with maybe some strong duct tape.
IN for all the professional carbon fiber guru comments..lol
Never seen so many Nervous Nancys as in cycling. It's hilarious.
Nice job.! Congratulations for this video.
i have a hairline crack on my carbon seat stay is it still possible to repair it? if yes can i still ride it? im light. the outer part i can feel the crack with my fingers the inner side where the wheel is i can feel the crack half way...i have a pic of the crack.
+MissHitAllTheTime yes that is an easy fix, difficult place but the crack is not so bad, fix it before it get bigger
which one do u recommend??

Godzilla Carbonworks Carbon Fiber Repair Kit Car Body Trim Free SHIP | eBay
a bit more pricey.
Real Carbon Fiber Uni Repair Kit for Added Stiffness Uni and Epoxy Resin | eBay
cheapest but i'm wondering if this will do the job?
is it strong? This can be a life ending if you ride a weak frame.
how about the air bubbles?
Great video. Thank you. Now I gotta keep an eye out for a good deal on a broken frame. Did you give up on putting the rivet back in? And don't you need to clear coat it to seal it?
Michael Bacon Thanks. I put the rivnut back in as well. Check my other video on that goo.gl/DMasU4. Clear coat would be a good idea, but I didn't bother with this one.
Good video, but i think the fiber layer was a bit too thick(low end stuff) for this operation? Option B: Get a steel frame and never worry about coming apart in your hands. Italian frames made 40 years ago are still amazing to ride on, enough said.
Steel is real indeed. I have a vintage Italian made Rossin in the fleet.
I have the same kit and I used half and half so what did I do wrong
What an incredible amateur and danger intent to "high tech" aprroach.
Whole video is a mess. Don´t believe this kind of narcissit gurúes.
Looks like a perfect way to balls up a very small repair.
Yeah, it was a sloppy job. I know better now thanks to all the free advice in the comments.
Spent about 500 miles on it and so far so good. th-cam.com/users/postUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA Pros:1. Very light2. Solid quality build3. Fast delivery: It arrived 5 weeks earlier than expected.4. Easy assemblyJust a few cons but nothing major:1. Cheap tin tubes and had flat on first day... but not a big deal. I replaced the tubes.2. Seat is a bit uncomfortable but that's pretty much the same situation with most bikes.3. Seat post is a bit long/high for a smaller size 48 bike - had to saw 2 inch off to fit properly. The lowest setting is too high. The post locking system does not seem to hold well (perhaps because I saw 2 inch off).4. wheels are not tubeless compatible (from what I can tell)
Enjoyed the vid. But like others have said, i think you went overboard. You could have fixed the rivet nut without the patch. If its a crack in the frame i could see this being a possible solution. But to be honest, i dont think id risk my life on a shotty crack patch.
The carbon fiber reacted with the less noble metal aluminum. Basically galvanic corrosion. Use only the most noble metals with carbon fiber. Aluminum should be avoided. If you must use aluminum on carbon fiber then electrically isolate the carbon from any less noble metals with a nylon dielectric material or "isolator" salt from your sweat will also degrade the carbon fiber over time unless the carbon fiber is coated properly with a 2 part urathane or 2 part polyurathane. good luck.
Wow, thanks for the info.
Just wished you epoxied the shift cables to the frame DA!
yep, I've learned a lot since making this video.
Does it works for chinese clincher Carbon rims?
Luis270893 Perhaps, depending on the damage you've got. If you're gonna discard the rim anyway, may as well try it out.
In my opinion, I would have undermined the hole a bit and bought a rubber that mixes that they say are strong as steel and that's it, the frame in that area was not broken.
thanks
How about painting work? Any update?
+kijang777 naw, too busy with other stuff to do. : (
Le tour de plants 🤣. What a name. Subs from me
hmm.. if I need the hole, when I pierce the hole?
I have a 2nd video about how to make a new hole and install a rivnut so the bottle cage can be reinstalled.
Le Tour de Plants - Vegan Cycling Thank you so much ! I try repair my frame that burnd by welding.. and rear brake hole(?) is included my repair zone wow.. thank you again@@
Fine repair (if you are not concerned about aesthetics) for a water bottle, but not the way to approach a structural repair.
Understood. thanks for the opinion.
Explain more please, what was done wrong for a structural repair?
I am not going to beat you up in the same fashion of the comments made earlier . This is a functional repair, not pretty but functional and I think that was the point. MORE IMPORTANT: You didn't mention anything about "masking up" before you started to perform any sanding. Any kind of dust is not going to bode well for you if you inhale it. MASK UP before you sand, a $3 mask is all you need from homedepot
Thanks, Lance
Are you still using the frame?
Yep, rode it today. strava/letourdeplants
You've got to be joking
Yes, this is a comedy channel.
Agree. Not a proper or correct repair.
Youre rad! Thanks for video this is holy grail for any(!) carbon frame)
Brahdda, I appreciate you taking the time, but IMHO this is a terrible way to do this repair. First off, way too much surface area affected, secondly, carbon fiber patch job looks shoddy as hell. Thirdly, ivalue of the bike was just destroyed to fix a simple water bottle holder. My point is that I'd NOT recommend this method for future viewers....might be good for more pertinent structural issues though, especially if taking better care to get the fiber patch looking decent.
Thanks Jonny, valid points.
I've got a similar issue on my carbon frame and to me this way of doing it seems like overkill (and it makes the frame pretty worthless when i sell it on). I'm tempted to just epoxy a pre-crushed rivnut into the hole left by the old rivnut, unless anyone has a better suggestion..
I had a similar problem. I just mixed up some resin, bunged up the hole, made a little Plasticine dam just in case I poured to much resin, then poured the resin around and let it seep into the affected areas. I removed the Plasticine, removed excess resin and wrapped it with pvc tape. Once it had cured I gently smoothed it over, masked the decals and spray painted the area. I then lacquered it and fitted a new riv nut. You cannot even tell it has been repaired.
The kit is now only $20 on Amazon, I recently cracked a carbon fork, & I want to repair it. seeing this let me know that I can do it my self. It is after all a hairline crack under 2". If anything I will repair & test then maybe sell it, yes it's cracked but the damage seems to be cosmetic. I thought for sure that squeezing the fork would cause it to snap, but it is still very rigid, & strong.
Crypto Que No way would I run a cracked carbon fork, even if you repaired it. That's just asking for a catastrophic failure. Hopefully you put the money you saved towards a good dental and medical insurance plan, because you'll need it for when you eat the pavement.
@@gregs7519 I agree, repair a fork (that's crazy)
a new fork is say, $35...the crack is prolly just stress on the paint
how to repair a small scratch on a carbon fiber frame:
fill it completely with molten titanium in a vacuum chamber.
let it cool
make a mold of the frame that is three inches thicker than the original.
insert the frame.
Put it in a vacuum chamber.
pour in molten titanium to fill the mold.
let it cool.
perfect. Your frame is now no longer strength-compromised.
Ok Martin, I just broke my seat tube. and I am about to try this......
Dude, I saw your FB post about your broken tube. You wouldn't believe the number of 'Nervous Nancys' who are too afraid to attempt their own repair. But if the decision is between 1) trashing the frame, 2) paying $500 for someone else to repair it, or 3) trying it yourself, why not try it? If your repair doesn't feel strong enough, you can always take it to a pro. : ) Good luck, John.
Do you need that much carbon fibre?
Josh Smart Perhaps not, but it worked out nicely.
no
I think was better, (as for all resin works) to do the procedure layer by layer, meaning .... you do the first layer, you let it dry, grid the area, put the second layer etc ..... I think this is the right way not to scrap the fabrics all together, creating a "thinner" - "weak" carbon layer ............. also, I think for a small damage like this you need to fix a smaller area ..... sorry for the criticism .... is only my opinion.......
talk about over doing it
Please wrap your parchment paper with electrical tape for some compression to smooth out the look and to show people how to get a bit more strength for those repairs that do need more strength, if they choose. The epoxy needs to make continuous contact, but the more you can squeeze it, out of the voids, the stronger the situation will be when cured in 3 days. Nice work though!
Thanks for the tips.
Perfect!
where to start lol
why do vegan bikers feel the need to have that they are vegan in their channel name
Just to help create awareness.
It makes them feel special... Whereas no one else really cares either way.
Do you know how to tell you are talking with a vegan? They will tell you.
They are bragging about it and we all consider it to be a form of faschism.

Vegans have brain size of a female squirrel.
6:16, wow just like mine when I bought it, NOT !!!!!
please make a video of repainting it.
+Yeon hee Lee i used fiber glass clear coat for boats after the carbon fix, then wait for that to dry properly then sand down again to create a ruff surface for the primer, use car paint primer then normal car paint on top then clear coat it afterwards
Health and safety...wear gloves
respirator
Please answer I liked your video
Ryan Coffman My instructions say 2:1 ratio of epoxy to hardener. That means 1oz of epoxy for 0.5oz of hardener, as an example.
monstrual job :D:D:D:D:D:D:D:D
Monstrual word.
batter before,the decals was totally dameged
yeah, but now it's theft detered
This is disturbing to watch!
I don't mind people repairing their bikes like that, but showing this as an example of how to it is just wrong.
With a little knowledge and thinking everyone can do a far better job, at home, without professional tools.
I appreciate the effort, but leave tutorials like these to those who know what they're doing and how to do it.
agree! the whole mess was unneccessary, and frankly looks like ass.
cleaning the hole and gluing in a new thread-thingy with silica (sand) filled epoxy would have done the job just aw well, and much more arsthetically pleasing.
+Sam Bebop Agree - I´d have just cleaned up the hole and used a new rivnut
What would you do differently?
Sam Bebop lllllll
and that new rivnut would fall out really fast due to cracks moving out from the hole as you can see in the video.
is that safe to ride??
Andrew Ramirez Yep. I ride it around 175 miles / week.
damn haha i go through 6 bikes per year once they crack my sponsors give me a new bike right now i have a Ridley noah fast with campigolo electric gears and Zipp tires
Andrew Ramirez What does all that have to do with the repair of this frame though? Unless you just wanted to show off what bike you are riding . . .
I like...thx
Thanks for the encouragement.
Wow...Just Wow. What a dogs breakfast....its great that you are prepared to try, but there is so much excess epoxy, no grade of carbon, it looks like a thick heavy weave cloth - total overkill for a small problem that didn't need such a repair. Yes most frames and carbon parts can be repaired at minimal weight gain but this is adding weight for free...
Thanks. How would you repair broken area under the rivnut?
Why did it need repairing?
It's not like you put in a new thread, so you literally achieved nothing except screwing up your bike.
Simply by putting in the next size rivnut...going from a 4mm to a 5mm screw is not the end of the world and I have done it before in about 20 minutes.
+TheFlytechguy looks like the nut sert wasn't even crimped so didn't even need next size up
He could have simply epoxied a new one in.
I would never ride a broken carbonfiber frame. The original fibercourse is interrupted and this could be dangerous.
aluminium is where it at
yep, alloy is good too.
Power sanding is too aggressive it's best to simply plane the paint off with a Stanley blade .😊🚲
+Ultraspontane I like using a tire iron
+carbon man by hand only, power tools and carbon frames don't mix
+Ultraspontane I usually just gnaw off the paint with my teeth. Works great.
It's a disaster to work this way !! but very very funny for a video
Glad you got a laugh. Actually, it wasn't a true disaster. It was no big deal really.
Caveman does carbon fiber.
I don't see a crack
Fuckin Mc Gywer.
I have an engineering degree and am a fibre glass boat builder and this is actually scary. Please do not do this to your bike and send it to a repair store. This guy has no clue how to use carbon fibre.
Would you know a link to a video which you believe shows the correct way to repair carbon?
😂
Its become an elized bike
That's a cosmetic repair not a constructional repair
true, true. Finally someone with observation skills and common sense.
good video i know a guy that diyed his frame like this and it does work he s being riding his s works for over a year ....all the negative comments are pansies once you get a couple of layers properly set frame will be strong and stiff
그냥 워런티 받으세요
all warranties are limited, so you will eventually have a bike that is out of warranty. 모든 보증은 제한되어 있습니다.
Le Tour de Plants In Korea, frames can be replaced when a crack occurs within the warranty period
@@LeTourDePlants I think my 1984 Trek 510 (steel tube) still carries a lifetime warranty but it also weighs around 30 pounds,. So to your point ... carbon fibre ... what warranty ?
Carbon specialized with cheapest water bottle cage possible...NICE.
Your point is what?
A more expensive bottle-holder wouldn't save more than a few grams, a carbon frame saves you many kilograms.
Just because people choose to have stronger and lighter frames doesn't mean they need it to be the most expensive aswell.
Just put a chinese carbon bottle cage for 7 bucks :D none can even tell its cheap af
I repair composites for a living, please do not do anything he is doing. Do not use thinners under any circumstances, ever. Carbon is laid up in a certain fashion to build in characteristics like strength, flexibility etc don't just lay it on. You would use equal parts reisn to fibre for example if you were adding 5g of fibre you would use 5g of resin it's called the volume fraction. Then you could wrap some release tape over it to minimise the voids.
Great advice. The TH-cam community would benefit if you made some instructional videos.
@@LeTourDePlants I completely understand, its easy to criticise. There are many really good videos on youtube, look at Easy Composites, they are really good and I can't add anything additional to them. But the way I see it is if you are willing to post a clip then you owe it to your target audience to get it right. Buying something off ebay and sticking it on is not correct, did you take in to account galvanic corrosion between the carbon and the (I assume) steel rivnut?
I have a TH-cam channel, I make furniture. I work with composites, I don't bring my work home.
