Hi,
I recently bought a new bike and the shop switched all of my 2-year old Shimano Ultegra components and FSA SL-K cranks over to a new frame (not sure if this is relevant). I ride 2 year old Mavic Ksyrium ES's.
When I ride, I occasionally get a really loud squealing noise that seems to only happen when I stop pedaling. A good example is that while riding up hill, it NEVER happens, but then going back down hill it seems to start squealing when I coast. As soon as I pedal, the noise disappears. It doesn't happen every time I coast, but does happen quite frequently. It's tough to describe, but it is a very loud squeal. It's not a creak, or a small squeak, and it never happens while pedaling.
My brake position looks fine. I just had the bottom bracket re-sealed, but the noise is still there.
Any ideas?
