Well I have a total of 5 rides in on the new SS and I have officially destroyed the ISIS Drive Bontrager Race Lite. The left side of the crank came off after a tough climb. I stopped to look and all the threads on both the Bottom bracket and the crank arm itself we stripped out completely. I have the parts but camera pics arn't the best in the dark Will try and take shots tomorrow. Went to a LBS and picked up a new crank.... hope this one works better!
