The SRAM GX Eagle T-Type 12-Speed Cassette is built to deliver exceptional shifting performance under load, making it a core component of the Eagle Transmission system. Its full X-SYNC design improves shift quality the harder you pedal, ensuring smooth, reliable gear changes even on demanding climbs.

A massive 520% gear range provides versatility for everything from steep ascents to fast descents, while refined progression in the low end—featuring 38T and 44T cogs—creates smoother transitions compared to previous 10–52T Eagle cassettes. Designed around a 55mm chainline, it reduces chain angle for improved durability and more precise shifting.

Installation is straightforward with a clearly marked Setup Cog for accurate alignment. The cassette uses a Pindome construction for gears 1–8 and a single-piece mini-cluster for gears 9–12, balancing strength and weight. Nickel plating enhances durability while keeping shifts quiet, and compatibility with the widely used XD driver body makes integration easy.
