I would like to upgrade my current bike that came with 9 speed sora groupset to a 10 speed groupset, I'm wondering if the 10 speed cassette is compatible with my current wheelset ?

    Actually I had sent an email asking the bike manufacturer but they say it won't work and I need to change the hub in order to fit in 10 speed cassette. So obviously they are lying to me ?

    As far as I am aware 9 and 10 speed Shimano hubs are the same.

    If it currently takes a 9 speed Sora cassette it will take a 10 speed Shimano cassette because it's the same width (Tiagra 10 speed) or narrower ( 105, Ultegra 10 speed) and will need a spacer.

    Maybe they are confusing it with the transition from 10 to 11 speed...
