I had refurbished the Specialized Rock Hopper my next-door neighbor gave me and was riding it to work one day. The rear derailleur went South and tossed the chain into the spokes. I replaced a lots, but the wheel simply had not been working out so I bought a new pair. New rear wheel has an 8/9/10 speed hub, so instead of messing around with a spacer for the 7 speed cassette I simply converted the entire bike to 8 speed inexpensively.
Now I have this 7 speed cassette for sale. I put a couple of hundred commuter miles on it riding to work. Its an HG41, 11-28 gearing (11, 13, 15, 18, 21, 24, 28), worked fantastic with the Sram 8 speed chain I have, consists of the lockring and has been degreased and cleaned extensively.
Oh, I also have the left/right 7 speed shifters with new cable televisions for sale cheaply, but haven't provided them.
If you have a rear wheel bring it along so we can check the fit on the spot.
I have the lockring device.
This is a cash money sale just. PLEASE ... bring precise currency.
