Product Description
Unleash your adventurous spirit and conquer any terrain with the SRAM Apex XPLR XG-1251 Cassette. Designed as the centerpiece for your gravel or all-road machine, this 12-speed, all-steel cassette delivers the perfect “sweet spot” of gearing for unpredictable surfaces and epic rides. It offers a wide 11-44T range, providing a massive 400% gear ratio that gives you both the high-end speed for fast gravel roads and the low-end torque to spin up the steepest, loosest climbs without breaking your rhythm. This is the ultimate tool for versatility, empowering you to say “yes” to any route.
SRAM´s XPLR (Explore) gearing philosophy is engineered specifically for the demands of single-chainring gravel riding. The intelligent gear progression features tight jumps between the smaller cogs, allowing you to maintain a smooth, consistent cadence when you’re pushing the pace on flat sections or paved transitions. As you shift into the larger cogs, the jumps become more decisive, providing significant relief exactly when you need it on punchy ascents and long, grinding climbs. This thoughtful design ensures you´re always in the right gear, with seamless, intuitive shifting that lets you focus on the ride ahead.
Built for exceptional durability and unwavering performance, the XG-1251 cassette is engineered to work flawlessly with SRAM Flattop chains and requires a SRAM XDR driver body. This combination ensures crisp, reliable shifting and a secure, stable interface that can withstand the rigors of off-road riding. Whether you´re embarking on a multi-day bikepacking trip, racing a gravel grinder, or simply exploring the backroads, the SRAM Apex XPLR cassette provides the range, reliability, and performance to help you ride further and faster than ever before.
