The GX Eagle Transmission (T-Type) Cassette is a core component behind Eagle Transmission’s class-leading shifting under load—both inboard and outboard. Its full X-SYNC design means the harder you pedal, the smoother it shifts.

Built around a 55mm chainline, it minimizes extreme chain angles for greater precision across the full range. The optimized 520% gear range features refined steps in the low end, thanks to larger 38T and 44T cogs before the 52T, offering smoother transitions than the traditional 10-52T Eagle cassette.

Installation is simple and foolproof with a clearly marked Setup Cog. The cassette uses a durable Pindome design for gears 1–8 and a lightweight one-piece mini-cluster for gears 9–12.
