The new SRAM RED Powerdome X is the most advanced cassette ever made. It's super light, deadly silent, and 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.
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 choice of design, material and production process
