Exogram: The new Hollow Carbon Construction starts in the crank arm and extends into the cranks’ spider. It maximizes the stiffness to weight ratio.
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.
GXP: GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance.
Yaw: With a front derailleur cage that 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 and precise, delivering an unmatched performance advantage in front shifting.
