SRAM's Force 22 Crankset takes a few cues from their top tier Red model, picking up not only 11-speed compatibility, but the same featherweight X-Glide R™ chainrings.
Carbon fiber arms keep the weight low, while a separate alloy spider and hidden fifth bolt boost stiffness compared to the previous Force crank. The 11-speed specific X Glide R™ chainrings feature a CNC-machined construction which also aids rigidity, plus advanced shift timing pins and ramps to provide fast, reliable gear changes when paired with the Yaw™ Front Derailleurs.
The Force 22 Exogram GXP Crankset is available in Standard (53/39T) and Compact (50/34T) chainring configurations. It's compatible with SRAM GXP Bottom Brackets and recommended for use with the Force or Red 22 Yaw™ Front Derailleurs only. Its bottom bracket is sold separately. Various arm lengths. Claimed weight: 714g (172.5mm).
