Cassette weight matters more than most drivetrain components because it's rotating mass at the wheel. The XG-1295 addresses this with a one-piece machined construction that eliminates the steel carrier found in lower-tier SRAM cassettes. X-Dome technology machines the 10-44 tooth cogs from a single block of steel, with only the 50-tooth climbing cog pinned separately. The result is a cassette that weighs roughly 100 grams less than the GX Eagle equivalent while maintaining the same gear range.

The 10-52 tooth spread provides Eagle's signature range without requiring a front derailleur. You get a 10-tooth starting cog for high-speed descents and paved approaches, then access to that 52-tooth bailout gear when the trail tilts vertical. The jump between cogs follows SRAM's calculated progression—tighter spacing at the smaller cogs where you're pedaling at speed, wider jumps at the large end where cadence variations matter less.

Installation uses SRAM's XD driver body, which has been standard on higher-end mountain wheels for years but isn't compatible with Shimano HG freehubs. If you're coming from an HG-based drivetrain, you'll need to swap the freehub body or source a new wheel. The XD interface locks the cassette in place with a single lockring and positions the smallest cog directly on the driver splines rather than threading onto the freehub.... Read More
