Product details:
Most road bars won't make you faster. The tops are flattened and shaped to slice wind and still fit within the UCI constraints for aspect ratios. This results in you saving 6.4 watts of effort at 30mph The unidirectional carbon-fiber composite material is what allows for this shaping to be so dramatic and so light, 240g, lighter than many high-performance aluminum bars on the market today. Thanks to the material, it was easy for them to route the control cables and housing through an intake port and out an outtake port at an angle that is easy to thread and easy to bend to get them directed toward their ultimate destination. Because keeping the wing-like top-section flat is important, Zipp also worked hard on setting the ramp angle just right so no one will need to tilt up their bars so the hoods are at the proper angle. The wing is designed to be ridden without tape covering it; so the shape was also designed to fit comfortably in your hands. They kept the reach short at 70mm and the drop at 128mm and mated those to an ergonomic shape so that just about everyone could fit these bars easily. There's a slight out sweep on the hooks to the drops of four degrees for greater wrist comfort. The best time trialist in the business, Tony Martin, had these put on his bike for a time trial where only conventional road bikes were allowed. And has kept them on ever since, taking advantage of these bars, and his amazing legs, to win on long solo attacks. The Zipp SL-70 Aero Road Bar is so fast the UCI should consider banning it.
