To further improve the transfer of power and to longevity of the pedal, this surface area is made of stainless steel molded directly into the pedal body. LIGHT: At a mere 122 grams (in Carbon Version, 130g in Composite), the Keo 2 MAX is one of the lightest pedals in its category. This has been achieved through the use of a carbon injection process allowing for weight reduction and improved durability. RELIABILITY: Particular attention was focused on reliability and provided through features such as: a carbon injected pedal body, a stainless steel cleat contact area, an oversized axle with dual seals, making this a pedal built to last. The new line of Keo 2 MAX pedals maintains a low cleat contact height even with the use of a steel oversize axle. The pedal is built with two miniature ball bearings (12mm inner x 18mm outer diameters) and a needle roller bearing. LOOK axles are only approved once they have survived a million cycles at 100 revolutions per minute with a 90kg (198lbs) load at the center of the pedal and an eccentric rotation (replicating a bump each revolution). This test largely surpasses current standards. Dual seals increase bearing longevity. ADJUSTABLE Q-FACTOR: Thanks to 14mm of threads on the new LOOK axle, the Q-factor may be extended by 2mm with the use of specific washers available separately. Use of these specific washers results in a Q-factor of 55mm versus the original 53mm.
