SRAM XG-1270 12-Speed 10-36 Cassette

Designed for the next generation of drivetrains—and the next generation of riders. The SRAM Force XG-1270 cassette is optimized for electronic shifting and features X-Range gearing technology. Smooth, precise shifts, from 10T on up.

TECHNOLOGY

• MINI CLUSTER

The MINI CLUSTER hybrid cassette construction combines three small cogs that are CNC machined out of a single block of billet steel with an additional eight cogs that are individually pinned together. The result: a cassette that’s light, durable and equipped with a gear range that’s a perfect fit for any ride.

• 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 rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85 mm 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 1.85 mm 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. We 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.
