The SRAM Red XG-1190-A2 11sp Cassette is super light and deadly silent.

With revised graphics to match SRAM RED eTap components, the PowerdomeX™ is still the most advanced cassette ever made. It's super light, deadly silent and delivers an undeniable performance advantage.

The nine cogs in the cog cluster are machined from a single block of high grade tool steel, increasing stiffness while weighing even less than a titanium cassette. Between each cog 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, and paired with the new SRAM Red rear derailleur, it delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear.

Technologies

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 SRAM has ever built.

StealthRing - Specially designed and incredibly durable elastomers placed in between the cassette’s cogs to eliminate vibrations and noise.

X-Glide - Imagine being able to shift smoothly at any time, no matter what. We’re 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, has an incredible impact on the way you ride. Flawless shifting means you’ll never again compromise your speed and power in unpredictable off-road terrain.

TRUVATIV’s 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 pin—rather than the middle of the chain link—you get double the shift opportunities. No more missed shifts, ever. X-Glide puts you in THE RIGHT GEAR, right now.
