As bikes have front and rear wheels, so too have they front- and rear-specific hubs. The front hub is simply designed to enable the wheel to spin, while the rear hub is a little more complex as it also forms part of the bike's transmission the cassette or sprocket which drives the rear wheel is attached to the rear hub, which on most bikes also features mechanism to allow you to coast or freewheel (exceptions being fixed-gear or 'fixie' bikes and track bikes). Your wheels spin more than any other part of your bike. Therefore, having the best bearings in this application is crucial to producing the best results.
