SRAM XS-1275 12-speed T-Type Cassette for GX Eagle Transmission

SRAM GX Eagle Transmission XS-1275 T-Type Cassette 12-Speed is a high-performance mountain bike cassette engineered specifically for SRAM's revolutionary Eagle Transmission drivetrain platform. Designed to deliver exceptional shifting precision under load, outstanding durability, and seamless drivetrain integration, the XS-1275 is the ideal cassette for riders seeking reliable trail, enduro, and e-MTB performance.

Built for use exclusively with SRAM Eagle Transmission rear derailleurs, the XS-1275 cassette features advanced T-Type design architecture that optimizes shifting performance across the entire gear range. The cassette utilizes a robust Mini Cluster construction for the smallest sprockets, while the larger sprockets are assembled using SRAM's durable Pindome design to balance strength, weight, and longevity.

The advanced X-Sync™ tooth profile and Cassette Mapping technology ensure smooth and accurate shifting, even under maximum pedaling load. Compared to previous Eagle cassettes, the largest sprockets feature more evenly spaced gear progression, helping riders maintain a consistent cadence on demanding terrain.

Designed around a 55mm chainline, the cassette reduces chain angle, improves drivetrain efficiency, minimizes wear, and enhances shifting precision. Its rugged construction also makes it an excellent choice for modern e-MTB applications.
