Cassette SRAM XG 1290 12V 10-33 Rainbow

SRAM XG 1290 12V 10-33 Rainbow Cassette

The RED XG-1290 is the workhorse among SRAM X-RANGE™ cassettes and shifts not only fast, but also smooth through its wide gear ratio range. The 12-speed cassette was developed specifically for the requirements of eTap AXS electronic wireless shifting systems and offers the greatest possible weight savings through its elaborate one-piece design. It works perfectly in conjunction with SRAM's RED Series Flattop® chain and eTap AXS front derailleur components.

Features of the SRAM RED XG-1290 cassette

• Revised construction for smoother, quicker shifts
• X-DOME™ design with a very lightweight sprocket set milled from a block of steel
• Progressive gear graduation (at least five gear jumps with a single tooth)
• small pinion with 10 teeth to extend the range of gears
• compatible with XDR freewheels

X-RANGE™ |To meet the various applications of modern road cycling, a drive system is required that offers the right gear in every situation. Since shifting operations on the rear derailleur are inherently more efficient than on the chainring, X-RANGE™ shifts part of the gear range from front to rear. While a smaller and more uniform difference of always 13 teeth is applied between the chainrings, the cassettes can offer a greater transmission range of up to 360%.

X-DOME™ | The one-piece design of X-DOME™ technology creates incredibly light, precise and robust cassettes. The open design not only repels dirt better, but also gives the component longer life and smoother shifting performance.
