Sram:
the workhorse of x-range™ gearing. The SRAM red® xg-1290 cassette progresses fluidly and quickly through a wider range of gears. It’s specifically designed for wireless electronic shifting and the one-piece design offers you the best in weight savings.
Things to remember
- updated design for smoother and faster shifting
- more gradual gear progression between cogs—at least five one-tooth jumps—while still offering a wider range
- 10-tooth start helps provide a wider gearing range
- designed to work with an xdr™ driver body
- one-piece machined steel x-dome™ design for weight savings
- all zipp wheels starting from 2012 are xdr™ ready
