This is the SRAM Force 22 Crankset. The Force 22 crankset delivers an upgrade in performance by utilizing unidirectional carbon in the crank arm matched to a forged alloy spider. And, like RED, the hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. The stunning X-GlideR™ chainrings are optimized for use with the YAW™ Technology in the front derailleur, delivering seamless, flawless performance. It comes in fullsize and compact ratios and in multiple crank arm lengths.

Features:

• Hidden bolt pattern leverages the characteristics of carbon fiber while presenting a sleek appearance.
• Stiffer X-GlideR™ chainrings feature thicker construction, advanced shift timing pins and ramps, which are optimized for shifting with the Yaw™ Front Derailleur.
