Best Mountain Bike Cassettes

Get ready to dive into the heart of your mountain bike’s performance powerhouse: the cassette. Sitting proudly on the rear wheel, this vital drivetrain component boasts a series of circular sprockets, each adorned with teeth that securely grip your chain.

The number of gears at your fingertips can vary, with mountain bike cassettes typically offering 9, 10, or 11 sprockets. Just imagine, a 10-sprocket cassette paired with two front chainrings delivers a whopping 20 gear options to tackle any terrain!

Our guide will cover the best mountain bike cassettes on the market for 8-11 speed bikes.

How are mountain bike cassettes sized?

Buying a new cassette can be confusing. Cassettes are sold in speeds, so a Shimano 11-speed cassette will have 11 sprockets with teeth.  They are then sized by the number of teeth each sprocket has, so an 11-40T will have 11 teeth on the smallest sprocket and 40 teeth on the largest sprocket.

Are cassette sizes interchangeable?

No. If you have a 10-speed cassette, it must be replaced with another 10 -speed cassette, unless you are upgrading your entire drivetrain.

Who are the top mountain bike cassette manufacturers?

There are two daddies: Shimano and Spram.

What is a mountain bike groupset?

A groupset is all the components that make up your MTB drivetrain. These include: Crankset, bottom bracket, shifters, derailleur, chain and cassette.
