3T Zefiro Team 42cm Carbon Dropbar w/Aero Extension: 3t at its best! ZEFIRO fuses the power and control of the road racer's drop bar with the low-drag form of the chrono rider's aerobar. The base unit combines the variable-radius, medium-drop bends of ERGOSUM with the aero wing of MISTRAL. Additionally, it has the unique Pi Wing, an adjustable forward extension with an aerofoil hand rest. The rider's forearms rest on broad silicon pads on the basebar's upper surface, while the hands and wrists fall into a natural, ergonomic position on the handrest. The result is a hybrid that provides super comfort for long solo efforts into the wind, and full control for out-of-the-saddle efforts in the bunch.This innovative new bar meets all current and anticipated rules on aero form in both ProTour and ITU codes and is currently being trialled by pro teams. It should also bring performance and comfort benefits to amateur century and sportive riders and triathlon contestants.
