It is generally good practice to replace your chain when you install a new cassette. We recommend SRAM (Formerly Sachs (Formerly Sedis)) chains to our Web customers. Click here for details.
|Standard Shimano 7-speed Cassettes:|
4.5 mm spacer to fit a 7-speed cassette onto a hub made for 8-, 9-, or 10-speed cassettes. CS004 $5.95
Shimano 9 Speed Cassette Spacers (for in between sprockets) 2.56mm CS009 $3.95If your cassette has bolts holding the sprockets together, you will need to remove the bolts. They are not necesssary, only intended as a convenience for rapid cassette swaps.

Custom 9-speed Cassettes by Sheldon Brown:
(NOTE: These are the only custom cassettes we make. Please do not ask about making others.)
These cassettes are made entirely from genuine Shimano parts (except the 34t cogs, which are made by IRD), rearranged to offer gearing options not otherwise available.
|CS915 Big Dozen HG-61||$79.95||12||13||14||16||18||21||24||28||32|
The "Big Dozen" is a good all-around cassette for wide-range systems with 46-48 tooth large chainrings.
|High & Wide||See the new Shimano HG-80 11-28t below||11||12||13||14||16||18||21||24||28|
The "High and Wide" is a good choice for bikes with small rear wheels.
|CS922 Century Special||126.95||13||14||15||17||19||21||24||27||30|
The "Century Special" is our most popular custom cassette. It works with all modern derailers, even short cage models.
|CS914 Century 12||119.95||12||13||15||17||19||21||24||27||30|
By popular demand, 12-30 range. You give up the 14 of the Century Special for the 12.
|CS923 Cyclotouriste 13||$132.95||13||15||17||19||21||24||27||30||34|
|CS925 Cyclotouriste 14||$132.95||14||15||17||19||21||24||27||30||34|
Our "Cyclotouriste" cassettes are an excellent choice for loaded touring bikes with full-sized chainrings, giving excellent climbing gears without sacrificing comfortable gear spacing for useless high end gears.

The Capreo hub/cassette is designed for bicycles with small drive wheels, typically folding bikes and recumbents.
The Capreo cassette is the only cassette that features sprockets smaller than 11 teeth. The sizes are:
Note: Capreo cassettes are not interchangeable with other Shimano cassettes. They only fit Capreo Freehubs , and Capreo Freehubs only work with Capreo cassettes.
The 2004 Dura-Ace hub has an aluminum Freehub body, so it only works with 10 speed cassettes.
This is not true of the Ultegra 10 hub.
The Ultegra 10 will take any standard Shimano cassette.
Dura-Ace 10 cassettes have titanium sprockets from 18 teeth and larger.
10-speed cassettes have a recess built into the back of the big spider module, allowing them to fit farther onto the Freehub body than older cassettes. This limits the possiblities of customizing the ratios, because you can't install a flat sprocket behind the spider module...you run out of clearance at the other end if you try.

These wide-range touring cassettes require a long-cage (SGS) rear derailer, such as Deore, LX, XT, XTR

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.
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.
We carry replacement Freehub ® bodies for Shimano cassette hubs.
7-speed bodies Part# Model Speeds Price 11 Tooth
CS015 STX-RC 7 29.95 Yes
For fixed-gear conversion, we also carry the Surly Fixxer Cassette Hub Converter
- "Silent Clutch" and pre '97 Dura-Ace Freehubs only take bodies specifically designed for them.
