Bike Cassettes

Improve your MTB or road bike with a premium quality bike cassette available in a range of sizes to suit all disciplines.

The sprockets in a mountain bike cassette are carefully engineered for smooth gear changes and work as a unit, which is why when you come to replace a cassette, all sprockets will be changed as one. Using advanced technology, SRAM, Shimano, and Campagnolo are some of the most sought-after brands for cyclists looking to upgrade or replace their cassette.

Chain Reaction have 10 speed, 11 speed and 12 speed bike cassette options, plus additional variations ideal for those looking for slick gear changes on the bike. We love everything bike, so discover all the drivetrain parts you need.
