Sram Force XG-1270 12-Speed Cassette 10-36tThe Sram Force XG-1270 12-Speed Cassette is optimized for electronic shifting and features our X-Range gearing technology. Smooth, precise shifts, from 10T on up. This is the 10-36t version and is engineered for compatibility with XDR driver body. The Mini Cluster Construction means that the first 4 cogs are CNC machined out of a single block of steel with 8 additional cogs that are pinned together. This results in weight savings and solid durability and longevity. The X-Range gearing has a wide range and smoother gear progression for an even smoother shifting experience. XDR is a universal mounting system for cassettes with less than 11t, lightweight and without requiring new rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85mm longer than XD for road hub applications and compatible with XD cassettes when installed with a 1.85mm spacer.
