The SRAM RED 22 Front Derailleur changes everything, including offering every gear combination with no chain rub or rasp. Instead of simply moving back and forth, the derailleur cage actually rotates to maintain a consistent angular relationship with the chain. We call it Yaw Technology, and it eliminates the need for shifter trim. As a result, shifts feel more direct, more precise, and combined with the new SRAM RED crankset and chainrings, delivers an unmatched performance advantage in front shifting. Yaw cage rotates in line with chain, improving the shifting speed and precision while eliminating the need for shifter trim. Best combination of aluminum and steel for the strongest and most durable cage we have ever made. Integrated chain spotter protects your frame without adding any extra clunk, and adjusts independently of the derailleur itself.
