Bike Cassettes for Replacements & Upgrades

Replacing a worn cassette or changing your gearing? Shop cassettes from SRAM, Shimano, microSHIFT, SunRace and more. The best starting point is the drivetrain already on your bike, whether that means keeping a proven setup running or planning a complete upgrade.

Match Speeds, Gear Range and Freehub

Check the cassette's speed count and compatibility with your shifter, derailleur and chain. Then match the freehub interface, such as HG, XD, XDR or Micro Spline, to your rear hub. Speed count alone doesn't identify the correct freehub. If you're changing the largest sprocket size, confirm that your derailleur supports the new range and follow the drivetrain manufacturer's chain-length guidance.

Eagle, T-Type and Shimano Options

This collection includes conventional SRAM Eagle and T-Type cassettes, Shimano options and cassettes for other drivetrain systems. Check the exact model and compatibility details instead of assuming parts with the same number of sprockets work together. There is no need to add another speed just to replace a worn cassette if your current drivetrain still suits your riding.

Our SRAM Eagle upgrade guide covers the earlier Eagle system. For a larger change, compare groupsets and drivetrain bundles and check which parts are included.

If you're unsure which cassette fits, send our team your current cassette, derailleur and rear-hub details. We'll help you find a replacement or a sensible gearing change.
