The SRAM Force 22 crankset delivers unprecedented performance on the road. This crankset borrows from the Red series by incorporating the hidden bolt design which provides greater stiffness and weight savings. The unidirectional carbon fiber arms and forged aluminum spider also contribute to these weight savings. The Force also utilizes SRAMs X-GlideR chainrings which are optimized for Yaw derailleurs and positive chain engagement. SRAMs design for the Force 22 adds up to seamless, flawless performance on the road.New, Never Used, OEM, This item is exactly as pictured and does not include retail packaging.Item SpecificationsColor: BlackWeight: 715g (53/39, GXP, 172.5mm)Spindle Type: GXPCrank Arm Length: 175mmPedal Size: 9/16Chainring Mount: 110mm 5-BoltChainring: 50/34TBB Included: N/AChain Compatability: 11-SpeedMaterial: Carbon/AluminumIntended Use: RoadSRAM
