Mavic's Zxellium Ultimates are the pinnacle of road pedal systems. They're ultra light and have oversize platforms for awesome power transfer. They boast carbon bodies, ceramic bearings, and titanium axles for an amazing weight of only 155 grams. Mavic's iClic engagement uses carbon springs for a great feel getting in and out. These pedals can be run with no cleat float (fixed foot position) or up to 10 degrees of lateral foot float.
