SRAM GX Eagle Cassette

Yes, the XS-1275 is designed specifically for the SRAM XD driver body standard. It will fit any wheelset currently running an XD driver.

The 55mm chainline is optimized to reduce the angle of the chain when you are in the largest cogs. This minimizes wear on both the chain and the cassette teeth, leading to smoother shifting and a longer lifespan for your drivetrain.

You will need a standard cassette lockring tool, but the installation process is simplified by the inclusion of a dedicated setup cog. This feature helps ensure your derailleur is perfectly aligned during the initial setup, making the process much more straightforward for home mechanics.

By using a durable pindome construction for the larger gears and a precision-machined mini-cluster for the smaller ones, SRAM balances weight and strength. You get a lightweight component that can still withstand the high torque loads of aggressive trail riding.

Yes, the X-SYNC design is specifically engineered to maintain smooth, consistent shifts even when you are pedaling hard under load. This is particularly noticeable on steep climbs where you might need to shift while putting significant power through the drivetrain.
