Unlock the full potential of your all-road and gravel bike with the SRAM XG-1251 D1 XPLR Cassette. Designed for the new era of drop-bar riding, this 12-speed cassette is the heart of the SRAM XPLR 1x-specific drivetrain, delivering the perfect gearing for any adventure that blends pavement with dirt. Whether you´re a dedicated gravel cycling enthusiast or a road cycling purist looking for more versatility, the XG-1251 is engineered to perform.
Make that daily ride from your front door a little spicier with some dirt. The 440% range of the XPLR XG-1251 cassette provides smooth gear progression when you’re sweating up gravel climbs, and tight jumps on the high end for when it’s time to drill it on asphalt. Shift features on each cog are optimized for electronic shifting, so you’ll get fast, smooth and precise shifts every time. This carefully engineered gear range ensures you have the power for steep ascents and the speed for fast flats, all without the complexity of a front derailleur.
Key Benefits & Technology
Engineered by SRAM for ultimate versatility, the XG-1251 cassette is packed with features that translate to a superior riding experience. The cornerstone is its X-Range gearing, which offers a wider range and a more usable, smoother gear progression. This means you spend more time in the right gear, pedaling efficiently and comfortably, no matter the terrain. The expansive 440% range is specifically what 1x gravel riders have been asking for, providing a low gear for grinding up loose climbs and a high gear to keep pace on the road.
This cassette is a key component of the integrated SRAM XPLR ecosystem and is designed to work flawlessly with XPLR 1x rear derailleurs and quiet, durable SRAM Flattop chains. Its full-pin construction utilizes Mini Cluster technology, which offers a lightweight yet robust design that´s built to withstand the rigors of mixed-terrain riding. The compatibility with the XDR driver body is what enables the use of a 10-tooth starting cog, crucial for achieving both the wide range and the tight gear jumps at the high end for sprinting. The result is a cassette that provides silent, reliable, and lightning-fast performance shift after shift.
