• Sort of related and apologies I asked in another thread, but..

    Will the Sunrace MS8 Wide-Ratio Cassette require a spacer on a road bike hub?
    If so am I better off with the SunRace CSRX1?

  • No idea is SunRace follow shimano or do their own thing.
    If we look at shimano 11 speed MTB cassettes, they are made to also fit on a 10 speed shimano freehub body. In the shimano MTB world they didn't change the size of the free hub body from 10 to 11 spd. So it means if you want to use an 11 spd shimano MTB cassette on an 11 spd road free hub body, a spacer is necessary. Now about that spacer, I found that the 1mm spacer is enough to tighten the lock ring. The 1.75 and 1.85mm spacer push the cassette more outboard. Try the 1mm spacer first.
