  • I’m pretty sure if you use an 11sp shimano MTB cassette it’ll fit a 10sp hub. I think the shimano HG800 cassette fits 10sp road wheels, I’m hoping someone can confirm...(edit- google seems to think I’m right)

    For some fucking retarded reason when shimano went 11sp the road dept made the freehub fractionally wider, the MTB department left the freehub as is and changed the cassette design to fit, go figure...

  • Huh. Thanks, I did not know that. Can someone confirm?

    My experience with MTB components is exactly 0, is the difference essentially that MTB cassettes are only offered in much wider ranges than road ones, or is there any further difference? Beyond the width thing?

  • Cog spacing is the same (I think!), obviously the ratios are different, but the way they’re designed is that MTB cassettes overhang the 11t cog beyond the end of the free hub overhangs the big sprocket inboard of the freehub to get the spread, where as road freehubs are slightly wider to accommodate the extra width of the cassette.

    I’d you google something to the effect of ‘hg800 10 speed freehub’ you’ll see what I mean.

    The other option is swap for a Campag freehub & casette, Campag also managed to make 11sp cassettes fit 10sp hubs (again someone correct me if I’m wrong). All 11sp cassettes are cross compatible in practice. That would make it easier to get road appropriate ratios.
