SRAM Rival GXP Yaw 110 BCD crankset

Specification: - Arm Material : Forged aluminum arms, Machined alloy spider - Chainring Material: Machined alloy rings - Weight: 873g (BB30 172.5mm 52x36 BB not included)/ 857g (GXP 172.5mm 52x36 BB not included) - Available Arm Lengths : 165mm, 167.5mm, 170mm, 172.5mm, 175mm, 177.5mm - Available Ratios : 52/36, 50/34, 46/36 - Compatibility : SRAM RED® 22, Force 22 & Rival 22 Yaw? front derailleurs/ SRAM PC 1170 & PC 1130 chains - Finish : Black - Recommended Chain : SRAM PC 1130 chain - Technology Highlight(s) : X-GlideR chainrings/ Hidden bolt configuration 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. X-GlideR Chainrings: - The chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance. Yaw?: - The front derailleur cage rotates to maintain a consistent angular relationship with the chain. Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct, more precise, and combined with the new Red crankset and chainrings, delivers an unmatched performance advantage in front shifting.
