Coming this October is a new pedal system from Look, the Keo Blade Aero. Used recently by Alberto Contador at the prologue and final time trial on the 97th Tour de France, the new pedal system proved to stay true to its name as an aerodynamic advantage on the road.
The prototype pedal system will have the same look and mechanisms that drive the current Keo Blade but features a different design specified to have aerodynamic performance due to a smoother lower area on the pedal. The Look Keo Blade Aero weighs 200 grams, making it slightly heavier than the current 195g Keo Blade. The increase was due to its new shape and material used. Because of this new overall structure of the Keo Blade Aero, Look claims that vertical plane stiffness in the pedal system has improved.
Availability of the Look Keo Blade Aero in the market will be around November-December 2010.
