Sometimes all it takes is a refresh. With updated graphics to match SRAM RED® eTap® components, the PowerdomeX™ remains the most advanced cassette ever made. It is super lightweight, quiet, and offers an undeniable performance advantage. The nine sprockets of the group are machined from a single block of high-quality tool steel, increasing stiffness while weighing less than a titanium cassette. Between each sprocket is a StealthRing™ elastomer to reduce vibration and noise. The cuts on the rear sprocket further reduce weight and increase stiffness. It is the final piece of the drivetrain puzzle and, paired with a SRAM RED® rear derailleur, delivers ultra-fast and ultra-quiet shifts that will always put you in the right gear.
