Shimano Deore XT CS-M770

The CS-M770 is compatible with standard Shimano/SRAM 8, 9, and 10-speed freehub bodies. As long as your current hub is a standard mountain bike freehub, it should install without issue.

This is an 11-34t cassette, which provides a wide gear range suitable for climbing steep trails while still offering enough top-end speed for flats and descents. The specific cog progression is 11-13-15-17-20-23-26-30-34.

The aluminum carrier reduces the overall weight of the cassette compared to steel-only models while maintaining the necessary stiffness. This rigidity ensures that your power is transferred efficiently to the wheel, even when you are shifting under load.

No, this cassette is specifically designed for 9-speed drivetrains. You will need a 9-speed shifter and a 9-speed derailleur to ensure the indexing and spacing work correctly.

This cassette weighs 323 grams. It strikes a solid balance between durability and weight savings, making it a reliable choice for riders who want to maintain their 9-speed setup without adding unnecessary bulk.
