SRAM XG-1275 GX Eagle T-Type Cassette

The SRAM XG-1275 GX Eagle T-Type cassette is a core component of SRAM’s latest Eagle Transmission (T-Type)ecosystem, delivering exceptional durability, precise shifting, and class-leading chain retention for modern mountain bikes.

Designed specifically for SRAM Transmission drivetrains, the XG-1275 features optimized tooth profiles and robust construction to handle high torque loads from both analog and e-MTB applications. Shifting performance is consistent under power, allowing riders to change gears confidently even during hard efforts on steep climbs.

The cassette mounts to an XD driver body and offers a wide gear range that supports everything from technical trail riding to long alpine climbs. Compared to previous GX Eagle cassettes, the T-Type version prioritizes strength, longevity, and drivetrain integration over weight savings—making it an excellent choice for aggressive riders and high-mileage bikes.
