great video! about to tackle the same project. not thrilled lol

People will probably stand in line to tell you "carbon can't be fixed" or "you're going to die first ride out". Don't listen to them. I did the same repair on a Roubaix and then put another 5k miles on it without issue. I've also repaired cracked steerers and those have also not killed me. Anyhow, really enjoyed the video. Think your repair looks great. And don't listen to those who haven't actually done carbon repair.

Great video, I damaged my top tube last night so planning to undertake a job on my top tube.

Ultegra crank snap? Thats crazy. It doesnt look too bad other than the paint coming off at first, but that coin ping definitely makes you wonder otherwise. With some delam possibly starting in the top layers, great call getting it sorted and nipping a potential crack/failure point in the bud. By the way, did you sand all the way around to a similar depth in that band around the dent? I also wonder how doing subsequent passes after the first one and sanding in-between would work, depending on the extent of the damage, and weighing effective strenght gains towards thickness added to the concerning area.. Basically I have a couple inches top layers crack running vertically right along my front derailleur mount that the previous owner kindly added to this giant tcr frame (probably due to jamming the chain and having it yank into the FD cage and pivoting it towards the seattube and ripping it) and i'm considering going this route. Crack didn't fully penetrate i checked, yet the FD is impacted and gives a little if pulled on. Otherwise Plan B i have prepared a steel L bracket matching the inner tube profile (endoscope) to insert+epoxy in order to bridge the entire area at the cost of two extra bolts at the backside of the tube + some surface work lol. Anyway great job, super informative and all the best with that top looking repair!

you did ok until the sanding. keep tape just outside the repair while sanding, it will protect from over sanding past the repair. clear box tape works fine, masking tape will get ruined while sanding. also use something to back the sand paper to get more evenness, foam sanding block, only because the frame tube has some curve, if it were straight use a straight edge. trying to sand a carbon repair evenly to transition to the original frame is near impossible especially when youre just using sand paper. and as you found after the paint you could see inconsistencies. also not sure if your shrink tape was perforated, that will help excess resin escape, otherwise poke holes after you shrink it. but for something like this shrink tape isnt necessary, wrapping it in scotch tape will give it more than enough compression more so than shrink tape depending on how you apply it.

Good job...but I feel u had a few more repairs with that epoxy

Cover the chain and drive train! That dust will get into them and cause extra wear

I would like to order this plastic roll used to wrap. How is this called? Thanks
