Sometimes all you need is a fresh coat of paint. With revised graphics to match SRAM RED e Tap components, the Powerdome X™ is still the most advanced cassette ever made. It's super light, deadly silent, & 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 Stealth Ring™ elastomer to reduce vibration & noise. Cutouts on the rear cog further reduce weight & add stiffness. It's the final piece in the drivetrain puzzle, & paired with the new SRAM Red rear derailleur, it delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear. Heat-treated, high-grade tool steel provides superlative durability & a beautiful finish Stealth Ring™ elastomers & advanced tooth profiles eliminate vibration & noise for a smooth, silent ride Aluminum cog: lighter, stiffer, stronger due to the design, material & production process ISO 4210 compliant
