The SRAM GX Eagle T-Type XS-1275 is a 12 speed, 10 to 52t cassette for SRAM Eagle Transmission drivetrains. Full X-SYNC teeth are shaped to shift cleanly while you are pedaling hard.

What it's for

The cassette for a GX level Eagle Transmission build on a 1x mountain bike. Its 520% range covers steep climbs and fast descents.

How it works

Full X-SYNC: every cog is shaped to work with the T-Type chain so shifts stay clean under load.

Construction: cogs 1 to 8 use SRAM's Pindome design and cogs 9 to 12 are a single mini cluster. Nickel plating adds wear resistance.

Setup Cog: one cog is clearly marked for derailleur setup.

55 mm chainline: the cassette is positioned for the Transmission chainline, which reduces chain angle.
