Message: >My gf's wheels have seen better days and she's in the market for some new ones. Due to her tastes, they have to be silver. I know, but she's pretty strong so I don't give too much crap! My question is: >Is the Shimano WH-R600 compatible with a 9 speed drive train? I've checked there site and quite frankly it confuses me. It says "10 spd only", but their tech compatibility chart makes me wonder. Evidfently there are some hubs that won't accept 9-spd. >Anybody try it or know for sure? >Thanks.. >WH-R600 The new 10 speed parts such as the new dura ace hubs will only work with the 10 speed cassettes. The new 10 speed ultegra hubs are 9/10 speed and you use a small spacer if you use a 10 speed cassette.
