Can I swap 9spd for 10spd Cassette?

Hello,

I've been given an older pair of wheels (Mavic Open Pro rims on Simano 105 hubs) that have a Shimano 105 9 spd cassette on them. They are about 10 years old. I want to use them as winter wheels on my Planet X to avoid using my Campagnolo Eurus wheels in the crap weather over the winter. The Campag wheels have a 10spd Ultegra cassette on them and are used on my Planet X with 10 spd Ultegra shifters. These are the older Ultegras (about three years old).

Can I simply take the old 9 spd cassette off these wheels I have been given and replace it with a 10 spd cassette so that I can use these wheels with my Planet X or is it more complicated than that?

Any advice/experience would be greatly appreciated!

Thanks,

Marcus

    For the most part yes, the same hubs are used for 8,9,10 speed. 11 speed is different.

    Sorry to be dim, but is it simply a matter of taking the 9 speed cassetee off and putting on a 10 spd cassette? If the hubs are the same then I would suspect that this is the case but I've leant in life that you shouldn't neccessarily assume! :-)

    Yes, you should be able to stick a 10 speed Shimano cassette on there and off you go. 10 speed Shimano 105 / Ultegra / DuraAce cassette would need the 0.5mm spacer that should be supplied with them. 10 speed Tiagra has the spacer effectively built in.

    Might need a new chain if the existing chain and cassette have worn significantly together

    Spacer needed because 10sp cassettes are actually narrower than 9sp.

    *with the exception of Tiagra 10 speed
