SRAM XS-1275 T-Type Cassette 12-Speed

The SRAM XS-1275 T-Type Cassette 12-Speed sits at the entry point of SRAM's T-Type transmission ecosystem, bringing the core engineering of Eagle's 12-speed drivetrain to riders who want that platform without committing to higher-tier components. It pairs with SRAM's T-Type chain and Unlimited or AXS rear derailleurs, operating as part of a system designed around consistent shifting under load — not just in controlled conditions. If you're building out a capable trail or all-mountain drivetrain on a budget, this is where the XS-1275 earns its place.

The cassette uses X-SYNC tooth profiling across its range, a geometry SRAM developed to keep the chain seated accurately through the drivetrain even when power is being applied mid-shift. The 10-52t range gives you a wide spread for technical climbing without sacrificing a usable top-end gear, and the stepped progression through the middle of the cassette is tuned to keep cadence changes manageable as you move through gears. A dedicated Setup Cog is included to simplify installation on the XD driver body, which makes getting the cassette seated and torqued correctly more straightforward — a small detail that matters when you're doing your own wrenching.

Design Benefits

1. T-Type system integration: The XS-1275 is built specifically for SRAM's T-Type transmission architecture, meaning the chain, cassette, and derailleur are engineered to work as a matched system — shifts stay consistent and repeatable whether you're on a flowy descent or grinding up loose singletrack.
2. Wide-range gearing without the gaps: The 10-52t spread covers serious elevation changes, and the step progression through the mid-range gears is calibrated so cadence transitions feel natural rather than abrupt — a meaningful consideration for longer trail rides or variable terrain.
3. Straightforward installation: The included Setup Cog removes ambiguity from the mounting process on an XD driver, making this cassette as approachable to install as it is to ride.
