A groundbreaking design introduced last year, now Yaw technology comes to the SRAM Force 22 front derailleur. It uses a modified parallelogram to actually rotate the derailleur cage as you shift. This gives more clearance for the chain in each respective chainring, so eliminating chain rub in any gear combination without the need for trim on the front shifter. The slim spring design gives more clearance for the frame, minimising any interference issues and the integrated (but removable) chain spotter removes any chance of chain damage to your frame. At only 79g (10.2g for the chain spotter), the Force 22 front derailleur is one big difference that doesn't add much.he front derailleur cage rotates to maintain a consistent angular relationship with the chain. Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct, more precise, and combined with the new Red crankset and chainrings, delivers an unmatched performance advantage in front shifting.
