The SRAM RED front derailleur, thanks to Yaw™ technology, eliminates the need for shifter trim. Instead of simply moving back and forth, the derailleur cage actually rotates to maintain a consistent angular relationship with the chain. As a result, shifts feel more direct and precise. Combined with the SRAM RED crankset and X-GlideR™ chainrings, it delivers an unmatched performance advantage in front shifting.
