SRAM XG-1090 10 Speed Cassette

The new Sram Red Powerdome X is the most advanced cassette ever made. It‘s super light, deadly silent, and delivers an undeniable performance advantage. The eight cogs in the middle are machined from a single block of high grade tool steel, increasing stiffness while weighing even less than a titanium cassette. Between each cog in the block is a StealthRing elastomer to reduce vibration and noise. Cutouts on the rear cog further create a lighter design and add stiffness. It‘s the final piece in the drivetrain puzzle, paired with the new Sram Red Rear Derailleur, delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear
