The SRAM Red OG-1090 cassette features superlight PowerDome construction: one-piece forged and CNC-machined of heat treated chromoly steel, then capped with an electroless nickel finish providing a 35% harder material than titanium. Open Glide technology also removes specific amounts of material from the smaller cogs, to allow for smoother shifting action between gears. The OG-1090 design merges stiffness, durability, and simplicity in a revolutionary new package. It features:
OpenGlide tooth profiling designed for optimal shifting performance
Compatible with SRAM and Shimano 10-speed applications.
Fits 8/9/10spd Shimano-spline freehub bodies for 10-speed shifting/spacing (does not fit DuraAce 10sp aluminum freehub bodies)
