With graphics to match SRAM RED¬Æ eTap¬Æ components, the PowerdomeX‚Ñ¢ 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‚Ñ¢ 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¬Æ rear derailleur, it delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear.
