Technical FAQ: Campagnolo carbon crank repair
Question: I bought a Ridley bike four years ago with Campy Record. Recently when I was changing pedals an insert in the crank arm came out along with the pedal. The local shop contacted Campy and was told that this was not a repairable part and the cranks have a three-year warranty. Is there an alternative to buying a new crank set? This appears to be an easy enough fix with a new threaded insert.
I can’t see how you’d repair that in such a way that it could withstand the huge loads that spot sees constantly. I suppose you could contact Calfee or someone else who does carbon repairs, but I would not hold out a lot of hope.
