So I was cleaning my bike on sunday ready for a ride on monday and I noticed a crack in the carbon fibre on my seat stay!! Treat a modern carbon frame well and there should be limited potential for degradation over a bike’s working life. Crack in paint on carbon frame - better pics.

Q: Will I lose frame strength by not compressing? In the end, the best advice I could find was to wrap the crack as tightly as possible with multiple layers of electrical tape, and to watch and listen for telltale cracking or crunching sounds. Can carbon be fixed? The only exception would be around a cable stop or a dropout that is bonded in. Chilled Carbon. Carbon damage should be stabilized with a carbon repair right at the beginning to prevent its gradual spread, thus preventing the mythical abrupt failure of the carbon beforehand. Even if you had a chunky aluminum frame, it is easy to save a pound or two with the ... the weakest points. Trying to find out if i need to replace the entire frame or if i could get the crack repaired and without breaking the bank!
