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. Cutouts on the rear cog further creates a lighter design and adds stiffness. 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.

• Heat-treated, high-grade tool steel gives superlative durability and a beautiful finish
• StealthRing elastomers and advanced tooth profiles eliminate vibration and noise for a smooth, silent ride
• Aluminum cog: lighter, stiffer, stronger due to the design, material and production process
• ISO 4210 compliant – see declaration of conformity for details
