I am sneeeeaky :devilzwhite: Back tire = teh dead. Bald in center now, and my new sprocket is going to need relpaced already. Ive got a tight spot in my chain, or some other kind of problem and its causing the chain to get extremely tight during certain spots. Making some loud grinding noises. It kinda freaked me out the whole time, and I deffinately tested my luck riding it the whole weekend. I will now tear it apart, fix it, and sell my bike... to prepare for the NEW HOTNESS 07 R1
