SRAM XX SL Eagle T-Type XS-1299 12-Speed Cassette – 10-52T

The SRAM XX SL Eagle T-Type XS-1299 Cassette is the lightest and most precise Eagle Transmission cassette SRAM has ever made. Designed for maximum performance, it features a fully machined hardened steel X-Dome architecture for gears 1-9 and an ultra-lightweight all-aluminum Spider Cog for gears 10-12, ensuring durability and weight savings.

With full X-SYNC technology, this cassette delivers optimized shifting under load, improving performance the harder you pedal. The 520% gear range offers improved low-end progression, with 52T stepping down through 44T and 38T for smoother transitions compared to previous 10-52T Eagle cassettes.

Designed for 55mm chainline compatibility, this setup reduces extreme chain angles, leading to longer wear and improved drivetrain precision. A clearly marked Setup Cog simplifies installation for perfect alignment.

This cassette is compatible with the widely used SRAM XD driver body, ensuring broad compatibility with Eagle Transmission-equipped bikes. Not suitable for E-MTB use.
