11 tooth sprockets

Cassettes that feature an 11 tooth sprocket are intended to fit "C" (Compact) hub bodies only. The spline grooves in the 11 do not run all the way through (it wouldn't be strong enough if they did.)

These cassettes can be fitted onto older bodies two ways:

• If you install a 1 mm spacer before the cassette, the cassette will fit, but the cassette will then be 1 mm farther to the right than it is intended to be. With most bikes, this won't be a problem, but if your frame has very tight clearance, or if you want to be able to interchange multiple rear wheels without having to re-adjust the derailer, this could be a problem.

• You can convert an older Freehub body to work with "C" type cassettes by grinding off the outer corners of the splines so that the 11 can fit on far enough to hold the rest of the cassette in place.

Loose Sprockets

We carry individual sprockets for Shimano cassettes, and can provide some sizes.
If you need a size that is not listed, Miche makes Shimano compatible cogs that are available from our Special Order Catalog

Although the Hyperglide ramps don't necessarily line up with non-standard sprockets, as a practical matter they tend to work just fine, even if they make a little click when you shift.

Note, in most cases, the smallest sprocket must have a built-in spacer, so, for instance, if you are converting 12-27 into a 13-32, you'll need to buy a new 13, even though the 12-27 comes with a 13.

The differences in thickness between 7-, 8- & 9-speed sprockets that don't have built-in spacers are so small that substituting 2 or 3 in a cassette won't have any affect on the indexing. Similarly, 8-speed top-position cogs work OK with 9-speed cassettes, even though the spacing is different, because the indexing for the smallest sprocket is regulated by the high-gear limit stop of the derailer, not by indexing of the shifter as with the other gears.

Individual Hyperglide Cassette Sprockets

Flat sprockets $9.95 each.

First Position (Top cog) Sprockets. $19.95 each.

For single speed applications, we also carry the BMX Freehub sprockets, which fit all Shimano Freehubs. See our Singlespeed Page.
