I'm looking to replace my two wheels and I've been recommended this Campagnolo Calima C17 Clincher Road Wheelset.

I currently have a Shimano Claris 8 speed cassette.

The wheels are described as 10/11 speed. From my reading around I think an 8 speed Shimano cassette should fit and 8/9/10 speed wheel with no problem. And I'd need a spacer for an 11 speed. Is this correct and if so how do I figure out what spacer I need? Thanks

A road 11 speed compatible wheelset will have a freehub body that is 36.75mm wide. A 8/9/10 speed compatible wheelset will have a freehub body that is 34.95mm wide - 1.8mm narrower.

You can fit 8, 9 and 10 speed cassettes on an 11 speed freehub body with the addition of a 1.8mm spacer.


You are correct about the cassette compatibility. If you are already shopping online, the easiest way is to do a web search for Shimano cassette spacer and pick one that adapts 8-10 speeds to 11-speed road freehub. It is possible that the wheelset already comes with such a spacer, so it is probably best to ask the seller first.
