yes that is exactly that they used. I just got off the phone with them and they said its not worth it, and accused me of torqueing to hard and said I should have bought a better bike. I have a 14 teeth gear on the back by the way. I do have the option of sending it to Norco but they said it might get rejected.
Still I think I might try, as I wouldn't mind getting a new frame and putting a better freewheel on? would that solve my problems?
