How BMX Cassettes Work

Summers bring about biking contests, and BMX bikers want to know how BMX cassettes work. Heavy duty mountaineering bikes have cassette hubs to ensure variable speed.

It is imperative to have a know-how on bike mechanism to understand the importance of a BMX cassette. The most important part of any bike is the chain crankset. The whole system of a chain that fixes itself on different cogs to give the tire a rotation is meant to utilize mechanical force to achieve maximum mileage. Heavy duty bikes like BMX have cassettes. BMX cassettes work to reduce exerted force with their cog wheels of different measurement. The purpose of a BMX cassette is to have better control over speed and force of the bike.

Before the invention of the bike cassette, free wheels were used. With the passage of time and introduction of larger sprockets, freewheel lost its eminence. With increasing size, pressure would mount on the axle making it weak in a freewheel system. Nowadays, the most successful mountaineering bikes are BMX. BMX cassettes were manufactured to replace free wheels and were a successful answer. BMX cassettes work with a system of cog wheels, axle for rotation and a ratchet mechanism. The bigger sprockets in a BMX cassette are held together by a threaded lockring fastened with three bolts.

The main purpose of a BMX cassette is to devise different gear speeds for the bike. This means converting mechanical energy exerted by the feet into maximum driving force. A lower or smaller gear by a BMX cassette would mean more exertion and smaller distance coverage but greater power and force. BMX cassettes work by transforming force exerted by the feet into force. The resulting energy is distributed equally over the whole system in a way that maximum mileage is obtained.
