The SRAM XX Eagle T-Type XS-1297 12-Speed Cassette sets a new standard for shifting performance, making it a cornerstone of the Eagle Transmission system. With its full X-Sync design, this 10-52t cassette ensures smoother and more reliable shifting under loadthe harder you pedal, the better it performs. Designed as an integrated component of the Eagle Transmission system, it works seamlessly with the derailleur for perfect alignment on any bike.

Boasting a massive 520% gear range, this cassette features refined gear progression in the lower range, with 44- and 38-tooth cogs delivering smoother transitions compared to traditional Eagle 10-52t cassettes. Its innovative design reduces extreme chain angles, promoting longer wear and greater precision throughout the gear range.

Installation is foolproof, thanks to a clearly marked Setup Cog. Built to last, the cassette employs a hardened tool steel X-Dome design for the cluster, while its 38t and 44t cogs are crafted from stamped steel and pinned to a lightweight aluminum 12th gear. With 55mm chainline compatibility and a widely available XD driver body, this cassette is engineered for exceptional durability, performance, and ease of use.
