I broke the frame of my fancy carbon-fiber Giant TCR C2 during the last lap of a race on Memorial Day. But Calfee, a local bike manufacturer that also offers frame repair services, managed to fix the crack. I was a bit skeptical, but I now have about 400 miles on the repaired frame, including a number of high-speed descents at 40 to 50 MPH, and it has performed great. So my verdict is in; repairing carbon-fiber frames is well worth a try!
Now I just have to get rid of some lingering soreness in my body from the hard crash.
