SRAM GX Eagle Transmission XS-1275 12-Speed Cassette 10-52T

The SRAM GX Eagle Transmission XS-1275 12-Speed Cassette delivers precise shifting, exceptional durability, and a wide 520% gear range for modern mountain bike drivetrains. Engineered specifically for SRAM Eagle Transmission T-Type systems, this cassette provides dependable shifting performance under load across demanding climbs, technical terrain, and aggressive trail riding.

Featuring SRAM's X-SYNC tooth profile, the GX Eagle Transmission cassette is designed to deliver smooth, consistent gear changes even under high pedaling forces. Its optimized 10–52T gearing includes 38T and 44T sprockets for improved progression through the largest climbing gears.

The cassette combines Pindome construction across the first eight sprockets with a one-piece MINI-CLUSTER design for the remaining four. This construction balances strength, durability, and weight for demanding mountain bike applications.

A clearly marked Setup Cog helps simplify SRAM Eagle Transmission drivetrain installation and adjustment, while the nickel-plated silver finish provides durability and a clean appearance.

Designed for SRAM XD freehub drivers, the XS-1275 cassette is an excellent replacement or upgrade for compatible SRAM Eagle Transmission drivetrains.
