Low Stack Height for Clearance, Aero Designed and Light Weight The XPRO 12 is the go-to pedal thanks to its carbon body and titanium axle. Power transfer and stability are maximised with a large, 725mm-squared surface area. The bottom fairing was created to improve aerodynamics and protect the carbon blade. TIME's patented pre-opened Iclic system allows for fast and easy cleat engagement. Tension adjustment on the carbon blade has three positions to manage the clamping mechanism's pressure precisely. The stack height is low, which keeps the pedal lightweight with good clearance.
