With graphics to match SRAM RED eTap components, the PowerdomeX is super light, 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 reduce weight and add stiffness. It's the final piece in the drivetrain puzzle, and paired with a SRAM RED rear derailleur, it delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear.

Features

• Compatible with SRAM RED eTap, RED, Force, Rival, and Apex.
• 11-30t, and 11-32t ratios are only compatible with WiFLi and 1x rear derailleurs.
• Hollow steel dome makes for the stiffest gear cluster at the lightest weight.
• Heat-treated, high-grade tool steel provides superlative durability and a beautiful finish. StealthRing elastomers and advanced tooth profiles eliminate vibration and noise for a smooth, silent ride
