Been a while since I updated the thread on my sons Trigger build, going back a year now he was racing at Steel City, he’d put in a conservative first run and going for his flying second.
He misjudged the dusty surface at the bomb hole and slid into a stump, right in front of a big audience. I didn’t see it but I heard the crowd give a big cheer when he got back up to complete his run. Talking to a marshal there was a moment they weren’t sure he was going to get up… I apologise to the photographer I bought a few pics from the event but couldn’t bring myself to buy this one…
The chainstay had hit the stump pretty hard, I have to say it looked pretty terminal, which was a shame as the build was only a few months old.
Rather than write off the frame I picked up a carbon repair kit for a fishing rod, as it included a fine weave carbon and heat activated compression tape. First step was to clean off the surface paint and get a better look at the damage. Now it’s not looking as bad with the surface layers sanded away. I filed out a rectangle where the new carbon fibre would sit.
Now I cut 3 pieces of carbon fibre with the layer pattern at 45 degrees, and put them in the space soaked in the epoxy. A bit of electrical tape keeps the epoxy off the good paintwork.
Now I cleared off the excess and wrapped in the shrink tape, keeping everything compressed while it cures.
Cured, cleaned and polished it looks pretty good. I did consider filling and painting but I decided it was neat enough as it was.
After a little bit of tentative riding, and checking the repair, normal honing resumed!
Nearly a year down the line, and one rear rim and headset later, the repair still looks good so I think you can say successful.
