I'm making a not so WAG that you have posted your concerns here prior to actually trying your 11-32 cassette on your new wheel. Is this correct? I've never heard of a hub being marketed as Shimano 9/10/11 where the 11 means MTB 11, which is actually 10. If you do actually have an old 10 speed wheel, the 34t cassette mentioned above is your solution. Please post an update.
