The new Force 22 crankset delivers an upgrade in performance by utilizing unidirectional carbon in the crank arm matched to a forged alloy spider. &, like RED, the hidden bolt pattern makes better use of carbon fiber to further improve stiffness & shed weight. The stunning X-Glide R chainrings are optimized for use with the Yaw™ Technology in the front derailleur, delivering seamless, flawless performance. It comes in fullsize & compact ratios & in multiple crank arm lengths. The chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminium CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, & nearly every shifting feature of the chainring. Chainrings, chain, & front derailleur are designed as a single integrated system for optimized performance.
