SRAM RED E1 XG-1290 12-Speed Cassette
The SRAM RED E1 XG-1290 12-Speed Cassette is SRAM’s lightest and most durable. It is designed for fast shifting and provides a gradual gear progression. This cassette uses a one-piece X-DOME design which makes it easy to install and reduces weight. Additionally, this cassette is now available in 10-30T and 10-36T options. It is intended for use with a XDR driver body.
Technology
XDR Driver Body
Universal mounting system which also allows for lighter and more versatile drivetrains.
X-DOME
