..are they needed in all cases?
I am currently trying to fit a Tiagra 10sp cassette onto a Shimano 9/10 sp Ultegra wheel, seems OK without a spacer, tightens up well but am reading that they are needed.
Just looked at my spare cassette (brand new still in packaging) and it has no spacer either
Help please.
