Mountain Bike Cassettes


Cassettes are an essential element of the drive train of your MTB. They provide the different gears you need to climb and descend and your bike’s cassette will determine the number of gears and drive possible with your bike. Top branded and highest-quality MTB cassette options are lightweight and make gear changes as smooth as silk. At Decathlon we stock a wide range of different brands and speeds of MTB cassette, from 5-speed up to 12.


9 Speed MTB Cassette

We stock a range of high quality 9 speed cassettes for mountain bikes. Different brands produce this type of cassette with leading Sram, Sunrace and Shimano all offering products in this range. Decathloc stock all elements of the mountain bike drivetrain, ensuring you can upgrade or replace every element as required for the best ride experience every time.


10 Speed MTB Cassette


The higher the speed, the more advanced and high-end the mountain bike cassette. 10 speed cassettes are also available from a range of reputable brands including Shimano and Sram. Mountain bike cassettes are constructed from a range of metals, with the lightest weight models using titanium and aluminium. It’s important to remember that a lighter cassette may not last quite as long as the metal itself is softer and wears out more quickly.


The gears are one of the most vital components of your mountain bike. At Decathlon we stock all elements of your bike’s gear system to ensure you can upgrade and enhance your MTB to your personal spec.
