It had never occurred to me that a CF frame could be repaired, but I just read in the road forum that Calfee and some others offer this service. Has anyone ever had this done? It isn't cheap, but it isn't nearly as much as even a cheap new frame.
I have a Kuota Kharma frame that I crashed that has hairline cracks where the internal lug is. It isn't a high-end CF frame, but I did like riding it.
