Hello all. Its almost time for me to change the rear tire. Im starting to see a flat spot in the center of the tire. Can anyone tell me the socket size i need to use to remove the nut on the rear wheel. Is there a specific torque setting when putting it back? I was looking at you tube videos and it doesn't look that hard to do. Many different ways. Has anyone tried the zip tie technique? Any pointers will be greatly appreciated. I will be going to pick up some tools for the bike, and wanna start doing (learning) my own adjustment and tune ups. Will be picking up tire irons, rim protectors, wheel balancer, and more. I don't wanna have to rely on the dealership all the times (oil changes, etc), not to mention all the money/time spend for something i could do my self. THX for your help.
