I have a 10 speed Giant mountain bike. I had to remove the rear wheel to get a new tire put on and now that I put the wheel back on the chain keeps slipping off when I am in low (the smallest one on the sprocket) gear. Also the gear indicator is reading between 5th and 6th when the chain is on the 7th (lowest) gear. Ths chain will stay on for a few hundred feet then pop off and I can not figure out why. It didn't have this problem before removing the tire. And I didn't adjust or change anything on the rear derailleurs either. I did have to remove one brake pad and shift it into the highest gear to get the wheel off, and when I put the wheel back on I made sure the chain went back on the highest gear.
Am I missing some simple adjustment here? Any help is greatly appreciated. I am no bike mechanic by any means.
