The SRAM Red Powerdome X cassette is the most advanced cassette ever made. The eight center cogs are machined from a single block of high grade tool steel, providing increased stiffness while still weighing less than a titanium cassette. In order to ensure a smooth and quiet ride, SRAM has built in special StealthRing elastomer in between each cog, designed to reduce vibration and noise. When paired with the SRAM Red rear derailleur, the Powerdome X cassette delivers ultra-fast, ultra-accurate, and ultra-quiet shifting.
