I have a pair of Mavic Ksyrium SL. Had them on my old bike with a 9 sp cassatte. Switched out the 9 sp with 10 sp and now there is "play" in the cassette. I added the Mavic spacer along with a small one. barely got the cassette back on...it's better but still has a little play. Is this normal? I don't remember having any movement with the 9 sp...
