Instead of simply moving back & forth, the derailleur cage actually rotates to maintain a consistent angular relationship with the chain. We call it Yaw Technology, & it eliminates the need for shifter trim. As a result, shifts feel more direct, more precise, & combined with the RED crankset & chainrings, delivers an unmatched performance advantage in front shifting.
