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.
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. The result is the stiffest and lightest cassette we’ve ever built.
StealthRing™
Specially designed and incredibly durable elastomers placed in between the cassette’s cogs to eliminate vibrations and noise.
