Thank you for posting this video, I had some chainstay damage but had it repaired by a "professional" and recently my chain took another bite out of the chainstay. Found out the previous repair was not very good. I was expecting to see carbon but saw a lot of bondo and carbon. I used your same techniques from this video and had great success. I tapped the repair with a coin afterwards to check for solid adhesion and thorough epoxy wetout and found no dull thuds. Just as you say, a pretty easy repair to do at home. So thank you for sharing your knowledge and tips, very appreciated and helpful! (My paint and clearcoat work leave much to be desired, however..)

Martin amazing concept, your skills and gifts are just awesome. My 5 year old son likes watching your videos, although he doesn’t understand what you say (yet). This Orbea is my favorite design, you made this just outstanding. Thinking to repaint my new MTB ;-). Take care lad. Greetings from Upper Austria.

You're a true hero for this. Love your vids man. Thanks for sharing your knowledge.

Another great video. Thanks for giving all of us information and knowledge on how to repair a bike frame. Keep up the great work

Omg the tire tube trick INGENIOUS!

Agreed! Tire trick is brilliant. Great to see the carbon repair. Thanks!

You are an amizing guy. I like your Videos so much. Bin Auszubildend als Zweiradmechatroniker mein Ziel in diesem Beruf, ist so Profi wie du zu werden. Beste Grüße und weiter so

Love that bike tube trick. Thanks - very helpful.

Martin, I am using your excellent tutorials to repaint my 2008 Cervélo RS frame. When I took the components off, I noticed some damage to the BB caused by the chainring rubbing on the fame. Your tutorial on how to repair this damage is extremely well done and provided perfect instructions. Thank you for taking the time to create this instructional videos and for posting them for all to see and use.

Very educational. Thanks for showing us the technique of patching carbon frame

Enjoy every one of you’re videos fantastic job 👈🏻👏🏻👏🏻👏🏻

Awesome safety message. Thanks for changing my ways.

That's impressive. Great job...

Brilliant. Love that you share these tips and skills. Have just sent a frame away for repair, but with these tips might just try myself next time. The shrinking tape and fast-set epoxy are great tip. One question with resins - are the slow set epoxies more durable than the quick set, or just useful for different things? I repaired my hockey stick a few years ago and was advised to get the slow setting epoxy as it cuould withstand more and would last longer.

I love your knowledgeable videos love u ETOE MY DEAR BROTHER

Absolutely fantastic. Good work, sir.

BTW what brand is the resin that you are you using?

Nice work. Some ideas for yur consideration... - use a wood glue utility brush instead of ear swab - mount a heat lamp bulb or two in a ceramic socket to ceiling above workbench to aid in epoxy wetting out CF, works great aircraft composite project - put layer of dacron peel ply on top of finished layup then cover with shrinking tape, when dry and peeled off has nice mat finish Thanks again....

Excellent tutorial! The only issue I seems you should be using a much slower curing epoxy - slower cure rates ultimately mean longer polymerization chains, which makes for a much stronger epoxy and therefore repair. Using a fast cure plus heat does not lend itself to good long term strength of repair.

Amazing Brother Thanks for sharing knowledge...

Could you list the material you used, resins, shrink tape, etc

Nice job on the repair 👍, don’t forget to use nitrile or vinyl-gloves when using epoxy. Epoxy allergy is a real thing, which everybody with enough exposure will get, and for your job something I really wouldn’t want to get.

Hey Martin, Started watching this week as I recently picked up the hobby of reworking old rusty bikes, and I have to say you are quite the talented character. Out of curiousity: did you do some kind of education (e.g. "Zweiradmechaniker / Meister") in Germany in order to be "certified" to do this in business terms? Keep up the great work.

Cooler Workshop😎😎 Art is producing such cool videos😎😎

Could you recommend a cheap carbon repair set (glue and some pieces of carbon mat) for home repair? There are some on Amazon but with mixed reviews.

Can you provide the links to where to buy the resin mix, carbon fiber tape, and the shrinking tape?

Hi Martin. Great video!!! I have damage in the same area as the bike in the video. My question is I’d like to used shrink tape around the repair during the curing process. What brand of shrink tape do you use? I can’t seem to find such think (tape with holes) in Australia. Now I do not own a baking room so would a heat gun work?

Hey Martin, I've watched many of your videos now and found them really useful for getting great tips and tricks associated with custom painting frames and helmets, I've had some good results using the techniques you have suggested, could you please let me know the type of mask / stencil film you cut and use along with the transfer tape as I have had some issues with various different types and not yet found one that is consistently reliable and that works very well for me. Thanks again for taking time out of your busy daily schedule to show us your amazing work.

your amazing bro

I have the same issue on the same area in my frame but mine looks like more structural damage (chain got stuck, I got pissed off...the rest is history) to the point that the carbon can be moved by putting pressure with the finger. I suppose that's not a DIY job...well put it this way i wouldn't be very confident going down hill knowing that I stuck some small pieces of Carbon myself....,😰. So the new frame is coming. Good thing is I have seem your DIY paint job and it's gonna look great! 👍

Tambien seria interesante que pusieras el enlace para comprar los productos que usas para ña reparacion de carbono algunas veces lo haces

Awesome video. Where can I find the shrinking tape?

I love your wideos

This was absolutely the best DIY video I have seen yet! Ausgezeichnet!! Just out of curiosity... could you use body filler on minor scratches and areas where the damage is too small for the tape or do you just use the resin?

@dbrassell1

2 жыл бұрын

When I've done this, I mix the epoxy, then cut small pieces of carbon fiber (roughly 1mm long) and mix it with the epoxy. Then apply to the scratch/ chip. Not really for crack in the carbon, but more as a filler. It sands, primes and paints well. Not sure if this the best way, but has turned out well for me

Great stuff. I’m enjoying the videos. I found the channel a few weeks ago when I picked up a used cervelo s3 frame that I want to strip and clear coat for the nude look. I found that the NDS rear prop out is worn by about 2mm so the wheel doesn’t sit correctly. Can I use resin to fill this in or carbon strips with resin ?

@ETOE Loved you video. Keep them coming. My apologies if this was not asked in some of your German comments. How do you know how much paint/epoxy needs to be prepped around the existing damaged carbon area in order to obtain a strong enough bond with the new carbon/epoxy being applied to maintain the strength needed, especially in high stress areas like the bottom bracket? And, do you try and match existing carbon fiber properties like low vs high modulus when making repairs?

@guinnesslover2970

No bike repairers do ,they use a generic epoxy and cloth. At best 50% resin to carbon but manufacturer uses prepeg at best 40% no repai should ever cost more than £100 with time and effort or they are taking the piss

Great workmanship. Curious how are those holes occurred and are you going re-drill them again especially the one for the cable in the rear. Any tip for deep scratch lines without patching the carbon fiber.

Hi. Excellent video... Can I bother you tell me the name of the shiking tape?? and where to find it?

I only want to remove the white logo on the downtube from a matte black carbon frame. Do I only need to sand it as in the video, or do I need to put something on after to protect the frame if I only want the matte black finish?

@ETOE, Awesome paint jobs but how do you know if there are no delamination on the accident chain stays in the existing carbon, do you have access to ultra scan?

Great video! I noticed that these didn't seem to be really bad structural breaks, would the same technic be okay for more sever breaks?

Hi Martin, thanx for uploading such great DIY tutorials. I‘ve discovered a crack on my fork‘s steerer tube (RockShox SID World Cup) and want to fix it with unidirectional HM prepregs. As I‘m very good in fixing various things, I‘m pretty confident of doing a decent job. But I have two questions: when it comes to baking it in the oven, I‘m unsure how the resin, which holds the stanchions in the crown would react at temperatures around 120 degrees Celsius. And can I compress the carbon layers sufficiently with heat shrinking tube instead of heat shrinking tape as I don‘t have to apply any additional resin? Thank you very much in advance🤘.

@@ETOE Oops, I‘ve just noticed your reply…three years later 😂. Thank you for your reply. In the mean time I managed to fix it with Toray T800 UD Prepreg. And although being a quite humble guy, I have to admit that I‘m pretty proud of the result. I managed to build an isolating door for the oven, where I could stick the steerer tube through, so only the tube got exposed to the heat. Now I‘m fixed and made some other accessories for my mountainbike, like a carbon fender for the fork and a copy of the frame holder for my mini pump. Thanx again and I‘d love to see more of your carbon repair videos.

Great videos, interesting and provides value. Question, I'm doing a relatively minor repair on the top tube road frame. I bought carbon fiber fabric cloth, 3k 200g/m2 plain weave. I need to buy the resin now, and at first i was going to buy 1:1 ratio resin off Amazon, but is there a specific resin i should be using. thanks very much.

@micw8422

Besides reference to UV protective resin, i've read folks using "marine-grade epoxy resin" and other resin's that were suppose to be stronger, which was not a 1:1 ratio? I can see the benifits for a fast resin, as you mentioned.

Hello etoe! Is it possible to remove the carbon patch after sticking it?

Das is good!

Were you able to paint the repair, or did you have to do the whole frame?

Donde consigues esos materiales?

Shoutout from Germany I have damage in the same spot on my BMC frame so this is an awesome video for me! it also answered my question of how deep is too deep when sanding down. One question I do have is why are you using unidirectional carbon sheets instead of a 90 degree twill? also, how far away should I tape from my damaged area? if I have a crack that's 5 mm in diameter, should I tape up to 10 mm away? 20? 50? is there a rule of thumb?
