It's been well advertised that the SRAM Red Yaw front derailleur has revolutionized mechanical front shifting. Tom Boonen won a pair of monuments on it last year. One could arguably claim that the simple concept of an uneven parallelogram that pivots about the seat tube, negating the need for a trim function and packaged into a lightweight and (importantly) stiff front dérailleur is the crown jewel of the new Red group. But does this seemingly unsung piece of metal really live up to the hype?
