...from noise. I can't seem to win lately, I had a noise coming from my rear wheel that sounded like something was loose, after much playing around I finally found out that the lock ring was really really loose, as soon as I tightened that up and now it was nice and quiet...at least for a while. Now that it's so quiet I'm starting to notice some other noises, currently the one driving me completely nuts is a noise coming from when I'm shifted to the middle of my cogset, I've tried everything that I can think of and can't seem to make it go away, I notice it more when I'm at a slower cadence however it's still there at the higher cadences. It's hard to describe the noise...it's a mix of sounding like it wants to change gears or is the bearings are loose however the wheel only has a few hundred miles on it and the cassette is fairly new. FYI, it's a Campy Veloce cassette with a Centaur rear derailleur and a Easton Vista SL wheel with campy freehub. Any help would be much appreciated.
