105 cassette with Apex groupset??

Hello there,

Im new to bike mechanics as just like to get on my bike and ride.

I have recently purchased some Easton EA90 SL wheels for my Dolan Mythos to help gain a few minutes for my Duathlon. I have an Sram apex groupset but the wheels came with a Dura Ace only freehub!! I have later found out that a 105 (5700) cassette will run on them but my question is will this run ok with my apex group?

I dont really want to purchase the expensive SRAM freehub but that is my second option.

Many thanks for any help in advance.

Gary

I haven't heard of a Dura Ace only freehub. Dura Ace cassettes aren't recommended on certain freehubs because they dainty, but thats obviously the opposite situation from what you have.

105 cassette will work fine with Apex. Might need to shorten the chain because those Apex cassettes can be pretty huge.

Shimano and SRAM cassettes are spaced identically and you can use either brand with the other's shifters and derailleurs. So, yes, the 105 cassette will work fine.

BTW, your "Dura Ace" freehub body must be a leftover. Shimano only used that aluminum 10-speed only design for a short time on the 7800-series hubs and one generation of Dura Ace and Ultegra pre-built wheels. They quickly went back to their Ti freehub body with is shorter splines that will accept 8,9 or 10-speed cassettes.

Many thanks for the reply.

Its actually Dura Ace & new shimano hence the 105 5700 fitting. My Apex cassette is a 11/28 and the 105 is 11/25 so your probably right.

Thanks again.
