Mihai started to hear cracking sound at 1400 watts. Seat stay cracked. There was also one more crack at the seat clamp area – possibly over clamped.
Seat stay fibers has been restored and reinforced – now it is stronger that it was.
Seat clamp area cracked at the joint where top tube meet seat stay – joint has been re-bonded and reinforced in order to prevent over tightening in the future.
Mihai with his Tarmac are back on the road racing.
