The SRAM XG-1090 cassette RED® PowerdomeX™ 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.
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.
Specially designed and incredibly durable elastomers placed in between the cassette’s cogs to eliminate vibrations and noise.
