The Speedplay Zero Stainless Steel Pedals are the most aerodynamic pedal system. Designed to increase speed by cutting wind resistance, this pedal has a tiny frontal area with a streamlined profile and dimpled surface. Every aspect of this pedal has been designed with speed and minimizing wind drag in mind, making it ideal for Triathlons and Time Trials where every second counts. The true locking mechanism on this pedal doesn't rely on spring tension for security, and this means entering and exiting the pedal is easy and unintended release is virtually impossible. These pedals also boast quality without compromise with 3 bearings compared to the others that only use 2 and metal-on-metal locking edges on the cleats for durability and safety. As well as this, the bearings allow for unbeatable cornering clearance, giving a 37 degree cornering.
