SRAM - Red Cassette XG-1290 Cassette - XDR | 12-speed
SRAM RED XG-1290 Cassette - XDR | 12-speed - Silver
The RED XG-1290 is the workhorse among SRAMs X-RANGE™ cassettes and shifts not only fast, but also smoothly through its wide gear ratio range. The 12-speed cassette was developed specifically for the requirements of the electronic eTap AXS wireless shifting systems and offers the greatest possible weight savings through its elaborate, one-piece design. It works perfectly in conjunction with the Flattop® chain of the RED series and SRAM's eTap AXS front derailleur components.
Features of the SRAM RED XG-1290 cassette
- revised construction for smoother and faster shifting
- X-DOME™ design with a very lightweight sprocket set milled from a steel block
- progressive gear graduation (at least five gear jumps with only one tooth)
- small sprocket with 10 teeth to extend the gear range
- compatible with XDR freewheels
- Manufacturer's note: Only suitable for use with Flattop® chains.
X-RANGE™ | To meet the diverse applications of modern road cycling, it requires a drivetrain system that offers the right gear in every situation. Since shifting operations at the rear derailleur are inherently more efficient than at the chainring, X-RANGE™ shifts some of the gear range from front to rear. While a smaller, uniform difference of always 13 teeth is applied between the chainrings, the cassettes can come up with a larger transmission range of up to 360 %.
X-DOME™ | The one-piece design of the X-DOME™ technology creates incredibly light, precise and robust cassettes. The open design not only repels dirt better, it also gives the component a longer life and smoother shifting performance.
