SRAM XS-1299 T-Type 12-Speed Road Cassette – Top-Tier Drivetrain Option

Description

The SRAM XS-1299 T-Type Cassette 12-Speed sits at the top of SRAM’s mountain drivetrain hierarchy — a 10-52T cassette built around an all-aluminum Spider Cog construction that makes it the lightest 10-52T cassette SRAM has produced. It’s designed specifically for the T-Type transmission system, where precise tooth geometry and consistent chainline matter at every point in the range.

The 55mm chainline compatibility keeps chain angles moderate across the full 12-speed spread, which translates to reduced wear and cleaner shifts under load. A dedicated Setup Cog is included to simplify installation and take the guesswork out of initial drivetrain setup. The cassette uses an XD driver body interface — a widely adopted standard that works with a broad range of rear hub options.
