Road Bike Cassettes

The Cassette on a road bike refers to the gearing on the back of the bike - the cassette is made up of a number of sprockets. The job of the Cassette is to provide gearing for the chain of your bike to run on - with different sprockets providing different performance allowing you to tailor the number of revolutions you can pedal a minute, to provide the most efficient performance. The larger the sprocket used, the easier it is to pedal - but the less ground you cover for each revolution on the pedals. The larger sprockets are ideal for climbing hills, whilst the smaller sprockets are best for speedy routes and downhill sections - preventing the rider from ‘spinning out’.

At Westbrook Cycles, we stock and supply a massive range of road bike cassettes - allowing you to replace and in some cases upgrade the cassettes on your road bike. Typically, the sprockets on road bikes are smaller than those on mountain bikes, less gap between gears is required because on the roads, there is less variable terrain compared to that encountered on a mountain bike.

Typically, Road Bike Cassettes have 11, 12 or 13 teeth on the smallest sprocket, with between 21 and 32 teeth on the larger sprocket. When selecting the right Cassette for your road bike, you need to consider whether or not your derailleur can accommodate the largest sprocket, as often a longer derailleur is needed to accommodate the longer chain which is required.

You can view the full range of cassettes here, and as always - if you have any questions about replacing or upgrading your road bike cassette - please do get in touch and we will be more than happy to answer any questions that you may have.
