Again, pertaining to the recycled $8 Rockhopper (It's now got $45
invested as I'm a big spender :P).
The rear mech is a Deore SIS 6 speed with a 6 speed cassette. Five
sprockets, their corresponding spacers and a sprocket that screws onto the
*outside* of the cassette as a lock ring.
From what I've researched, Shimano built 6, 7, and 8 speeds on this
particular Uniglide cassette, the difference simply being the spacers.
Mine's set up 13-31, which is a bit broad for the city and the shifting is
rather noisy, albeit accurate. I'm wanting to go 13-26.
I've got a bunch of sprockets from a Sram cassette I broke up to get some
spacers for my SS project, and they've got a couple thousand more miles to
spare. These will fit fine on the UG body if I grind off the large "tooth"
that's specific to the hyperglide body.
So far so good, in theory at least, It all depends on the Sram sprockets
being the same thickness as the UG sprockets. I'm not going to go make
myself a chain whip if they ain't--but if they are, it seems to be a cheap
way to keep using this UG body (I don't mind investing garage time on this
bike as it's interesting play, but don't want to throw money at it). 6
speeds is plenty for 'round town, but the 13-31 spread makes the jumps
between gears a little annoying. The shifting promises to be much improved
as well.
Any gearheads care to comment?
