Bike Cassettes

Bike cassettes play a crucial role in bike drivetrains, providing the necessary gears for both climbing and descending. Whether on road bikes or mountain bikes, cassettes work in tandem with derailleurs to facilitate gear changes. High-end mountain bike groupsets typically feature 12-speed cassettes, while 11-speed options are common across both road and mountain bikes. Premium cassettes are designed to be lightweight and ensure smooth shifting and here at Sigma Sports you'll find bike cassettes from component brands such as SRAM, Shimano, Campagnolo and many more.
