• 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 elastomers and advanced tooth profiles eliminate vibration and noise for a smooth, silent ride.
• Aluminum cog: lighter, stiffer, stronger due to the design, material and production process.

Technology

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 weve ever built. StealthRing Specially designed and incredibly durable elastomers placed in between the cassettes cogs to eliminate vibrations and noise. X-Glide Imagine being able to shift smoothly at any time, no matter what. SRAM is talking full-power shifts. Up, down, whatever the trail demands. The benefit of the X-Glide drivetrain is simple, yet, when you think about it, incredibly impactful to the way you ride. Flawless shifting means youll never again compromise your speed and power in unpredictable off-road terrain. Heres how SRAM did it: TRUVATIVs crank engineers threw away the old standards and developed a new chainring geometry from the ground up. They precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pinrather than the middle of the chain linkyou get double the shift opportunities.
