. This pedal is ideal for anyone who competes in Time Trials or Triathlon Events, where every second counts. Due to their aerodynamic design, they have been proven to increase rider speed by highly reducing wind resistance and minimising wind drag. Unlike the inexact set-up of traditional cleats, each of the three critical foot-axis adjustments of Zero Aero Walkable™ Cleats can be set or changed without affecting the position of the other two adjustments. This feature also eliminates guesswork and misalignment when replacing cleats. The cleat design is also convenient as with the Aero Base Plate installed, the cleats can be worn whilst walking Features: Highly AerodynamicWALKABLE™ CLEATS included53mm Spindle LengthEasy MaintenanceFits any road shoe with 3 or 4 mount holes on the basePedals weigh 105grams (each)Cleats weigh 84g (3 Hole mounting), 130g (4 hole mounting)Note: Zero Aero pedals are not compatible with Speedplay Light Action and X-Series cleats.
