Back in early 2014 I fixed a crack in my Ksyrium Elite rear wheel by wrapping it in carbon. 3 years later I still ride those wheels and probably have put at least a couple thousand on them though they are currently on my spare bike. The repair shows no signs of failure yet.
A while back I was riding my JAKE THE SNAKE, and I could hear some strange klunky noises on big bumps. After the ride I saw that the seat tube had cracked. Actually the seat tube has had a tiny crack in it since I bought the frame on ebay. The frame has a small dent and in the middle of the dent was a tiny little crack. I rode it for 3 years like that.
Since I was riding gravel Sunday morning I decided to attempt a carbon wrap around the tube. I didn’t waste time trying to carefully remove the paint. I just ground it off haphazardly. Next I drilled holes in the ends of the crack which now wrapped around the tube.
I treated the frame with aluminum treatment so epoxy would stick and I haphazardly begin wrapping epoxy smeared carbon around the frame. Once I’d wrapped it twice I wrapped the whole section tightly in electrical tape to flatten and squish out the epoxy. The next morning I rode the bike on 60 miles of intense gravel hills. It seems fine.
The center of a seat tube on a bike is very low stress. right…
