Shimano Dura-Ace 12-25 9-speed cassette. New in box. $200.00

Part# CA-01

Shimano's engineers went out of their way to design an astonishingly light and efficient cogset.

  • The five largest sprockets are mounted on their own super-light carriers that both reduce weight and increase rigidity.
  • The sprocket teeth are carefully shaped and contoured to optimize shifting. All unnecessary material has been cut away.
  • The lock ring is aluminum alloy and the three largest cogs are titanium.
  • Cog teeth are: 12, 13, 14, 15, 17, 19, 21, 23, 25

Note: This cassette does not have a lockring. Instead, the 13-tooth cog is threaded. This cassette will only work on cassette bodies with threads on the outside of the body.

It requires two chainwhips to remove.

Shimano HG70-C 7-speed 11-19 cassette. Lightly used, $50.00

Important: This rare cassette works only on Hyperglide-C freehub bodies. The standard 7-speed Hyperglide bodies will not accept the 11-tooth outer cog. The Hyperglide-C body had the ends of the splines shortened so that it could accept the 11-tooth cog. This cogset came on LX Hyper-C groups, among others.

We have several: #1 | #2 | #3 | #4

Shimano Uniglide 7-speed 13-24 cassette. Used, $65.00

Uniglide cassettes use a threaded top gear (small) sprocket to secure all the sprockets in place. They were used on pre-1990 Shimano cassette hubs. Dura Ace Uniglide cassettes use a different small-cog for a lock-ring than standard Uniglide cassettes such as this one.
