The SRAM Red 22 front derailleur is a game changer. It can handle every gear combination including Standard, Compact and Wi-Fli with no chain rub or gear grinding. SRAM uses a mix of aluminum and steel in the cage to make their most durable and strongest cage ever. They even managed to get the total weight a few grams lighter than their 10-speed Yaw front derailleur.
Yaw technology means the derailleur cage actually rotates to maintain a consistent angular relationship with the chain. This eliminates the need for shifter trim so you are never "that guy" in the group with the chain noisily rubbing the derailleur cage. 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.
Included with the front derailleur is a chain spotter also known as a chain catcher. The included SRAM chain spotter is nicely made and can be adjusted independently of the front derailleur. It prevents the chain from being dropped on the inside and is an insurance policy that effectively protects expensive carbon frames.
Compatibility is with SRAM Red 22 & Force 22 Front Shift/Brake levers & X GLide R Chainrings.
