SRAM XPLR XG-1251 D1 12-Speed Cassette

SRAM XPLR XG-1251 D1 12-Speed Cassette The SRAM XPLR XG-1251 D1 12-Speed Cassette has been conceived for the challenges of gravel riding; so it includes an X-Range; 10-44 sprocket formation to ensure that the correct cadence can always be found; whatever the topography. This 440% ratio range is split across twelve sprockets to minimise jumps between the gears and is designed to work optimally with a 1x chainring configuration and XPLR rear derailleurs. MINI CLUSTER technology sees the four smallest sprockets machined from a single piece of steel; while the remaining eight larger sprockets are individually stamped and pinned together; resulting in lower weight and extra durability. The tooth profiling is suitable for Flattop chains; while the connection to the rear wheel hub is via the XDR mounting pattern.
