i broke one, not ct but the other one, i think it was down to wrong tension for me though, ive got a year so far though out of my ct one and its still running strong. noone said they were indestructable but they definitely work better than a chain. the worst thing that can happen to a belt is twisting if incorrectly tensioned it can twist upon picking up shit. its just a bastard they cost so much. out of interest graham did you buy the gates tool to remove the sprocket?
