I recently acquired a set of wheels that have a 7 speed freehub. the freehub is not long enough to accommodate an 8/9/10 speed cassette.
After reading Sheldon Browns post on 9 of 10 on 7 ..
Any 7-speed Shimano Hyperglide Freehub will actually work with 8 or 9 sprockets, without any modification! What you need to do is to use 8 of the sprockets from a 9-speed cassette, with the 9-speed spacers -- or 9 of the sprockets from a 10-speed cassette.
I am hoping this means I will be able to take a 10 speed cassette, remove the smallest sprocket and end up with a 9 speed cassette that will fit my 7 speed hub.
I would like to know if this is actually possible, if anyone has done this and knows it works? - and also, with this configuration, will I be able to use an indexed 9 speed shifter + chain and the spacing be okay?
