SRAM Force XG-1270 E1 12-Speed Cassette

No matter what your aspirations or ride styles are, Force has you covered. Customize your drivetrain for your needs with 12-Speeds offered in a 10-28T, 10-30T, 10-33T or 10-36T range. Pair with any of SRAM's chainrings for your dream gearing setup.

Full Pin

Full Pin technology uses eleven lightweight, stamped cogs held together with 123 high-strength stainless steel pins. The result: a cassette that’s light, durable and equipped with SRAM’s super wide gear range that’s a perfect fit for any ride. The open design similar to SRAM's X-Dome cassette aids in mud clearance, giving you cleaner shifting performance and longer component life.

XDR

The XDR Driver Body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the cassette is installed with a 1.85mm spacer.

X-Range

Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings enabled by AXS. With X-Range, you’re always in the right gear.

X-Range achieves wider range and tighter jumps by going to a 12-Speed cassette, but also by moving some of the gear range from the front of the drivetrain to the back. We’ve employed smaller chainrings with a consistent 13T difference, while giving the cassettes a 10T-start for wider range (Up to 10-36, or 360%!). That means you can stay on the same ring longer, requiring fewer front shifts, which are inherently less efficient than rear shifts. And when a front shift is executed, the smaller jump is smoother and allows you to get to the right cadence with fewer compensation shifts in the rear. Fewer, faster front shifts make it easier for you to find the right gear, and that’s a distinct performance advantage relative to traditional drivetrains.

By starting X-Range cassettes with a 10T cog, SRAM's able to keep the cogs and chainrings smaller overall, eliminating the potential weight gain of a wide-range 11-tooth start drivetrain. It's the best way to expand range and keep small jumps between cogs.

More range, tighter jumps, and smoother shifts. What's not to love? With X-Range, getting everything you’ve always wanted in a drivetrain has never been simpler.
