Bicycle Cassette Replacement

On a multi-speed bicycle, there is a cogset or “bike cassettes” (multiple rear sprockets) that attaches to the rear hub on the rear wheel.  The use of the multiple gears on the rear bicycle cassettes are by the aid of a rear derailleur that allows the chain to travel up and down the sprockets.  These cogsets come in two varieties, bike cassettes and freewheels, freewheels are the newer/current development and both look almost identical in the installed state and are NOT interchangeable.  These terms are often incorrectly used interchangeably, but fall into different categories of drive train components.

A freewheel consists of the rear set of sprockets and a ratcheting system in a single assembly that mounts on a threaded hub on the rear axel and locked with a locking nut to the axel to prevent it from backing off.  This system is common on older bicycles.

Bicycle Cassettes differ from freewheels in that the cogsets are mounted to a internally splined tube of which that splined tube is fitted over a mating splined shaft on the rear hub and axel assembly.  This assemble if locked onto the mating slpine shafts by use of a lockring.

Not all of our available bicycle cassette replacement products are listed on our website, we sell the following brands: American Classic, Campgnolo, Interloc Racing Design, Shimano and SRAM.  Please contact customer service if you do not see the item you are looking for.
