Sram: the SRAM red front derailleur, thanks to yaw™ technology, changes everything, eliminating 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.Yaw™ technologyslim spring design eliminates frame interferenceoptimized for shifting with x-glider™ chainringsprecision install markingsintegrated chain spotter protects your frame without adding any extra clunk and adjusts independently of the derailleur itself
