I made a bunch of CF containers and epoxyed some right on the frame. Same with that 3" band. It is wet wrapped 2 layers, that makes it squash proof and distributes the tube bending force of the brake arm clamp holder. And besides that I had to spend 2 days hammering out a DIY steel clamp that needs a hard surface to support it. I have more CF added on than is used to make several whole CF bikes. LOL. You can buy CF kits for small jobs. I also got my fork bent from the set 50 mm to 66 mm rake, for my 70d angle and now perfect 60.5 mm trail.
