Our custom hubs use "thread on" freewheels, not cassettes.

See the difference in "Freewheels and Cassettes".

Most bikes that cost over $400.00 will use a "cassette".

If your wheel has a cassette it's better and cheaper to buy a New Double wall Alum rim and order the 7 speed freewheel.

This way you can keep your old wheel or sell it to cover the cost of the new wheel.

Our CNC machined Four bearing hub made in the USA is probably much better then the hub you now have.

Information about Freewheels and Cassette Freehubs They're NOT the same! This particular page is intended to help you determine which type your bike is equipped with, because there is a great deal of confusion about which is which.

The terms "freewheel" and "cassette" are often used interchangeably, an error that causes a lot of wasted time and money.

Freewheels for Threaded Hubs: Traditional rear hubs came with a standardized set of threads to which a standard freewheel/sprocket cluster could be screwed on. This allowed any brand of freewheel to be mounted on any brand of hub. If you wore out your sprockets, or wanted different gear ratios, you could unscrew the cluster and install a new one.

Almost all bikes made through the late 1980s used this system.

Cassette Freehubs Over the last few years the Shimano "Freehub" has largely replaced the conventional threaded rear hub. It is sad to lose the brand interchangeability that formerly existed.
