I went for a short ride today about 1 block to a friend's house and I noticed a clicking noise coming from the rear wheel. When I came back home I put it up on the rear stand and turned the wheel over a few times to see if i could figure it out. It makes the clicking noise after 1 full rotation and it sounds like it's coming from inside the wheel somewhere. I checked the chain and no binds in it and I just lubed it about 100 miles ago. The bike has 10k miles on it now and I've only owned it for the last 2k and it's never made the noise before. I put a new rear tire on it 100 miles ago and no noises or problems until now. Could it be the bearing or maybe just something stuck inside the wheel? I would like to know what it is before I ride again.
