SRAM Red CS-XG-1290-D1 12s cassette | 10-28T

The RED XG-1290 is the workhorse among SRAM's X-RANGE™ cassettes and not only shifts quickly but also smoothly thanks to its wide gear range. The 12-speed cassette was specially developed for the requirements of the electronic eTap AXS wireless shifting systems and offers the greatest possible weight savings thanks to its sophisticated, one-piece design. It works perfectly in combination with the Flattop® chain from the RED series and SRAM's eTap AXS derailleur components.
