SRAM XG-1190 11 Speed A2 Cassette – Silver – 11-25T

Sometimes all you need is a fresh coat of paint. With revised graphics to match SRAM RED eTap components, the PowerdomeX™ is still the most advanced cassette ever made. It's super light, deadly silent, and delivers an undeniable performance advantage. The nine cogs in the cog cluster are machined from a single block of high grade tool steel, increasing stiffness while weighing even less than a titanium cassette. Between each cog is a StealthRing™ elastomer to reduce vibration and noise.  It's the final piece in the drivetrain puzzle, and paired with the new SRAM Red rear derailleur, it delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear.
