What makes the SRAM GX Eagle T-Type XS-1275 cassette different?

The SRAM GX Eagle T-Type XS-1275 is engineered specifically for the Eagle Transmission (T-Type) system, where the cassette and derailleur interface directly for perfect alignment on every bike. It features a Pindome design on gears 1-8 and a single-piece Mini Cluster for gears 9-12, with durable nickel plating for a quieter, longer-lasting cassette. The full X-SYNC design means the harder you pedal, the better it shifts.

The 10-52t range delivers 520-percent gear spread, with larger 38 and 44-tooth cogs before the 52-tooth cog for smoother gear steps on the low end compared to the original Eagle 10-52. A clearly marked Setup Cog makes installation straightforward. Requires an XD driver body.

GX T-Type is the workhorse Transmission cassette: proven durability, clean aesthetics, and full compatibility with every Eagle Transmission shifter and derailleur. If you are running a GX Eagle Transmission drivetrain or building one up, this is the cassette that completes the system.
