The LBS tried to install it and said they couldn't do it because my SRAM cassette was incompatible with the freehub. My documentation that came with the SRAM 1070 and everything else I've read states that it is compatible with all "shimano compatible driver body" EXCEPT Dura Ace. My cassette says CS-6600 right on it so it aint Dura Ace. Anyone else replace an Ultegra cassette with a SRAM 1070?
If you have the old cassette off and try to install the new Sram cassette it should be obvious whether or not it will work. Ask the shop to physically show you what they are talking about or try it yourself.
