SRAM Force 1 GXP 130 BCD crankset

The SRAM Force® 1 crankset brings to cyclocross a game-changing upgrade in performance and reliability by combining the durability, simplicity, and efficiency of SRAM’s Force 22 road combined with our MTB 1x technology, X-SYNC™. Features: - SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control, crucial in cyclocross - Unidirectional carbon in crank arm matched to a forged alloy spider for lightweight and durability - Chainrings available in (110 BCD) 38, 40, 42, 44, 46, 48, 50, (130BCD) 52 and 54 teeth to conquer every course from sand dunes to gravel-road assaults - Single-ring drivetrain simplifies functionality Specifications: - Arm Material: Carbon arms with forged aluminum removable spider - Weight: 679g-24mm, 172.5mm, 50T, no BB - Compatibility: 110 and 130 BCD, SRAM 10- or 11-speed chains - Finish: Natural carbon arms - Recommended Chain: PC 1170 - Technology Highlight(s): X-SYNC™ / Hidden Bolt configuration - Other: Chainring and GXP cups not included Technology: BB30: Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction. GXP®: GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance. PressFit™: A variant of the external GXP bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. It requires no change to the crank spindle length and diameter. Pressfit 30™: This is a new design led by SRAM. It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching. X-SYNC™: SRAM X-SYNC™ 1X chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1X™ drivetrain.
