It's the front derailleur that changed everything, now with Sram Force 22 Braze On Front Derailleur, giving riders the freedom to shift with incredible speed into either chainring, with no trim & no chain rasp. The Yaw rotating front derailleur cage was just one more elegant solution to a problem that plagued drivetrains for decades. Instead of multiple shifts using trim, with confusing microshifts, the SRAM Force 22 Yaw Front Derailleur actually rotates to maintain a consistent angular relationship with the chain. As a result, shifts feel more direct, more precise, system that works as one with the chain, crankset & chainrings.
