Various Manufacturers Single Cassette Sprockets BMX Type
The Shimano MX66s are always in short supply so we are stocking these from various manufacturers.
These are made to fit the Shimano BMX Freehub ®, but they fit all Shimano cassette hubs ever made. Unlike the sprockets made for derailer cassettes, they have tall teeth, shaped to keep the chain on, not to make it easy to shift off!
