I had my bike at the shop the other day, and they adjusted my chain tension among other things. However, I've noticed a grinding-type noise coming from my rear wheel and I'm not sure what it could be.
At first I thought it was the chain rubbing on the chainguard and didn't think too much of it, but it appears to be coming from the axle. Could the axle bolts be too tight?
I rode out to meet someone about 30 miles out, and when I got there I smelled something burning. I rode it back and parked it, but I don't know if I may have screwed something up. I didn't smell anything on my return trip, but the grind is still there.
Any thoughts?
