I have put about 9,000 miles on my Mavic Ksyrium ES wheels in just over 2 years. While the rear wheel rotates very smoothly, I am hearing some bearing noise. I don't have any looseness or tightness in the hub but there is some very slight ball movement noise in the bearings as the wheel rotates freely without the chain on.
What type of life should I expect on these bearings?
Who supplies replacement bearings for Mavic Ksyrium ES wheels?
