The SRAM RED 22 Powerdome X™ is the most advanced cassette ever made. Super light, deadly silent, and precise. The nine cogs in the middle are machined from a single block of high-grade tool steel, increasing stiffness while weighing less than a titanium cassette. Between each cog in the block sits a StealthRing™ elastomer to reduce vibration and noise. Cut-outs on the rear cog further reduce weight and add stiffness. And now with the addition of the 16T cog, it allows for a better cadence control.
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.
