Hi, See pics for short. Then read on... Noticed today that the nut that secures the adjustment nut was missing (so 1 instead of 2). That was suspicious. Went to a friend and found one with the same thread. Adjusted the chain and noticed extremely uneven wear and relatively loose axel nut on the left side. Double weird. Ok. Maybe chain/sprocket are close to the end of the life, I thought. Thus started to secure the nuts and then the bolt broke off. fcuk, fcuk, fcuk. What will it take to fix it? Is the bike still safe to ride? (Prob not really). But maybe at least to the dealer to argue about warranty. Did 12k service at the end of Dec at PS (former Geoff Taylor). Now on 15-16k. So what now?
