1. My chain on the back is rubbing against the next lower gear. It makes this sound when i pedal backwards because it's rubbing against the next lower gear when it enters the gear. What do i do, should i adjust the L or H screw?
2. My bike makes a small buzzing noise in the back when i make a u-turn. i can feel the vibration also. a person told me it's becuz the hub is loose or something. what's the problem and how do i fix it?
