Large and Resistant Cleat Contact Area
For a more efficient and more comfortable pedal stroke, the Keo 2 MAX has a cleat contact surface area 12% larger than the Keo Carbon. 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.
Particular attention was focused on reliability and provided through features such as: 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 (reference NF EN 14781). Dual seals help to increase bearing longevity.
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.
this pedal is great light and stiff. but one comment that i like to make is the pedal cleat surface is too small for me. i got regular hot spot during long ride that lead to pain on my leg. this pedal is great over all, but does not suite my anatomy of my leg. thus i switch back to my shimano SPD-SL pedal.
