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. My carbon repair video: http://goo.gl/MPXUuI The kit I bought from ebay: http://goo.gl/eQyprr OR Search on ebay for keywords like this "carbon fiber cloth kit" http://goo.gl/F50liY 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.

why do vegan bikers feel the need to have that they are vegan in their channel name

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

Fuckin Mc Gywer.

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?

Hey, what was the sander you used? I would like to purchase one

what do u think? any differences? with the one u buy on ebay?? -
You've got to be joking

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.

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! -
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...
-
Just buy an aluminum bike and you don't have to worry about it. Carbon is for weight weenies.
-
batter before,the decals was totally dameged
-
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 -
😂

good enough for a newbie like me. Thanks... that took away the fear.
-
Not very good repair....For the next time puts tape on the carbon ends... and at the end peel ply
In this way you will ... save time and the finish will be perfect -
Walmart bikes :)

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 -
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. -
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.
