Shimano Dura-Ace cassette (or cog set, or sprockets if you prefer), hailing from Japan and in production during the 1980s. Made from steel and weighing in at 308 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.

The cassette (or cog set, or sprockets if you prefer)'s been carefully cleaned, thoroughly checked by one of our mechanics and graded as very good condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy, and please consider that cassette (or cog set, or sprockets if you prefer)s wear with chains, so used cassette (or cog set, or sprockets if you prefer)s can occasionally skip when partnered with new (and some used) chains. This can usually be avoided by using a compatible used chain of similar age, but there is no way for us to confirm which chain will work with which cassette (or cog set, or sprockets if you prefer).

▼HELP SECTION

Speed - the number of cogs on the cassette.

Spline Pattern - the shape of the cogs where they slide on to the freehub body, this must match the spline pattern of your hub to able to fit. In the 1980s Shimano introduced Uniglide cassettes that share the same spline pattern as their now standard Hyperglide, but the smallest sprocket threads on to the hub to secure it rather than using a conventional lockring, these will only fit hubs with a threaded section on the outside of the freehub body.

Range - the number of teeth on the smalles and largest cogs, this gives you an indication of how hard or easy the gearing will be, the lower the number the harder the gears. The tooth count of the cogs inbetween are usually evenly spaced, ie: a 6 speed 14-24 freewheel would likely have cog sizes 14, 16, 18, 20, 22 & 24.
