SRAM Red XG 1090 X Dome Bicycle Cassette Size 43065

The SRAM Red XG 1090 X Dome Bicycle Cassette 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 reduce weight 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. PowerdomeX Inspired from the combination of OG1090 SRAM RED and the XG 1099 SRAM XX cassettes, the heat treated high grade tool steel features hollow construction with CNC machined cogs and rear cut outs for reduced weight and added stiffness.
