Sram Force unlocks the effortless simplicity & ultimate versatility of AXS wireless technology for a wider audience than ever before. More progressive X-Range gearing across a greater variety of groupset configurations exposes the true capability of any bike & allows the rider to ride faster, farther, & easier The Sram Force XG-1270 12-speed cassette is optimized for electronic shifting with Sram X-Range gearing technology which centers around the development of the 10-tooth smallest sprocket. By creating a harder gear on the cassette Sram are able to reduce the size of chainrings correspondingly whilst still achieving an overall increase in both high & low ends of the gear range. The 10-tooth sprocket has also enabled Sram to reconsider the way riders progress through the gears with more 1-tooth jumps in the cassette maintaining even cadence for a smoother pedaling experience. Three size options from a low 26T up to a wide range 33T allow for drivetrain personalization across all 12-speed AXS road groupsets.
