The SRAM Force XG-1270 cassette is designed for the next generation of drivetrains and riders. It features X-Range gearing technology for smooth, precise shifts, with a 10T cog for wider range. The Mini Cluster construction reduces weight and increases durability. This cassette is designed to work with an XDR driver body. The 10-36T option provides even more range and requires the correct Force eTap AXS rear derailleur. Available in Silver and Black.
