SRAM Red Rainbow 10-28T Cassette

SRAM Red Cassette 10-28T XG-1290 XDR Rainbow

The SRAM RED Rainbow 10-28 cassette is a versatile X-RANGE™ cassette that offers a smooth and fast drivetrain. Designed specifically for eTap AXS Wireless electronic shifting systems, it is lightweight and made from a single block of steel, offering the greatest possible weight savings. This 12-speed cassette works great with RED's Flattop® chain and SRAM 's eTap AXS front derailleur components.

The RED XG-1290 cassette is designed with X-DOME™ technology, which offers a very light sprocket unit, machined from a block of steel, for smooth and precise shifting. With at least five speed jumps with a single tooth and a small 10-tooth cog to widen the drivetrain range, this cassette is compatible with XDR freewheels. It is important to note that this cassette should only be used with Flattop® chains.

The X-RANGE™ range is designed to meet the demands of modern racing bike users. It offers a wide range of gears, up to 360%, by moving part of the gear range from front to rear. The X-DOME™ technology in this cassette is incredibly light, precise and strong, providing long life and smooth shifting performance.
