The SRAM RED front derailleur, thanks to Yaw technology, changes everything by 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. The SRAM RED derailleur delivers an unmatched performance advantage in front shifting.FeaturesSRAM Road 11-speed compatibleYaw 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 itselfSpecificationsColor: Silver/BlackWeight: 69g (10.2g Chain Spotter)Clamp Type: Braze-OnCapacity: 16TMax.
