Versatility. Range. Precision. Built for Every Style of Riding.

The SRAM Force XG-1270 E1 12-speed cassette brings modern gearing, smooth cadence control, and durable construction to riders who want maximum versatility across road, gravel, racing, and endurance riding. With four available ranges — 10–28T, 10–30T, 10–33T, and 10–36T — this cassette allows you to tailor your drivetrain to your riding style, whether you're chasing speed on the flats or conquering steep climbs.

Engineered around SRAM’s intelligent X-Range™ gearing, the XG-1270 E1 delivers wider range with smaller, more consistent jumps between gears, ensuring you stay in the perfect cadence no matter the terrain. Its FULL PIN™ construction pairs lightweight materials with long-term durability, while the matte nickel-chrome finish ensures quiet operation mile after mile.

Designed for use with Road Flattop D1 and E1 chains, and fully compatible with both 1x and 2x AXS drivetrains, the Force XG-1270 E1 is your go-to choice for a modern, adaptable, and high-performance setup.
