I was wondering if anyone knows a definitive answer to whether the 10sp SRAM cassettes such as those included in the Rival/Force groupsets would fit onto a FH-6500 Ultegra Rear Hub?
Assuming the new SRAM cassettes are 'exactly' compatible with Shimano 10sp cassettes, Shimano states that _all_ new 10sp shimano cassettes will fit on FH-6600/ 8-9sp Freehubs. However, Shimano also says that the WH-6500 wheelset (which seems to use the FH-6500 freehub body) is not compatible with some of the 10sp Shimano Cassettes (11-23 and 12-23 gear combos). I'm aiming to get a 11-23 SRAM Rival Cassette, so I'm afraid it won't fit onto my FH-6500 hub...
