SRAM Red XG-1090 10-Speed X-Dome Cassette

Experience the ultimate in road performance with the SRAM Red XG-1090 10-speed X-Dome Cassette to keep your bike rolling fast and smooth when it's time to do some drivetrain service.

The new SRAM RED Powerdome X is the most advanced cassette ever made. It's super light, deadly silent, and delivers an undeniable performance advantage. The eight cogs in the middle are machined from a single block of high grade tool steel, increasing stiffness while weighing even less than a titanium cassette. Between each cog in the block is a StealthRing elastomer to reduce vibration and noise. Cutouts on the rear cog further reduce weight and add stiffness.
