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 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.
SRAM Red XG1090 10-Speed Cassette Features:
Hollow steel dome makes for the stiffest gear cluster ever at the lightest weight.
Heat-treated, high-grade tool steel provide superlative durability and a beautiful finish.
StealthRing specially designed and incredibly durable elastomers placed in between the cassette's cogs to eliminate vibrations and noise.
Aluminum cog: lighter, stiffer, stronger due to the choice of design, material and production process.
Powerdome X: 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. The result is the stiffest and lightest cassette we've ever built.
