Good enough for knighthood.
When it set out to develop the Zero Aero Ti Pedals into "the most aerodynamic pedal system" in the industry, Speedplay set itself an ambitious but not altogether uncharacteristic goal. After all, this is the company that effectively inverted the traditional design of pedals. Given that history of ingenuity, we're not surprised that so storied a name as Wiggins himself chose to use the Zero Aero pedals for his successful hour record attempt. Given that the titanium spindle anchoring the Zero Aero Ti system to the crank arms makes them the lightest of the family, we suspect these may be the actual model Sir Wiggo used.
The Zero Aero owes its wind-dodging abilities to a handful of design tweaks, including a reduced frontal area, a streamlined profile, and the kind of dimpling that we've already seen employed to revolutionize the wheelset industry. The dimpling extends to the cleat, which is housed in a walkable, rubberized shell that's contoured to create a seamless transition from pedal to cleat, denying the wind a foothold on any pronounced transitional ridges.
Like the standard Zero pedals, the Zero Aero models feature 15-degrees of micro-adjustable float and independently adjustable fore/aft, side-to-side, and rotational positions. The Zero's low stack height nets more pedaling efficiency and corner clearance while also contributing to the Zero Aero system's streamlined, low-profile aerodynamics.
