I'll share the limited experience I have, though others have much more. The older Uniglide cassettes had identical, evenly spaced tabs on the cogs, while the newer and more easily available Hyperglide cogs have one tab wider than the rest, so that the cog can only mount in one position, i.e can't be rotated. A Hyperglide cassette can be used on an old Uniglide hub by grinding down the wide tabs to the width of the others using a Dremel tool. I did this sucessfully to install a 7 speed Hyperglide cassette on a 1988 7 speed Uniglide hub. There might be some problems with fitting an 8 speed cassette on a hub designed for 6 speeds, but I'd think you could probably go to 7 speed at least.

(old 32 new 36) is it possible to just swap the freewheels resp. the cassette bodies? how is that done? and what tools do i need? if anyone has done this before or is expierienced with these older parts i would be grateful for help. martin glaettli in foggy winterthur, switzerland --
