The axle of the new Look Kéo Classic 3 is made of oversize steel. It consists of a micro ball bearing (12 mm internal x 18 mm external) and a flanged bush, for better resistance to stress. A spacer is placed to keep the bush. It limits friction and allows better fluidity at the time of rotation. A new procedure for checking the coupling of the axis line in the body also allows us to guarantee greater reliability of our pedals. The LOOK axis lines are validated only at the end of a rotation test of 2 million cycles at 100 rpm with a load of 90 kg on the center of the pedal and an eccentric rotation (which creates an impact with each revolution). This test is much more rigorous than the one foreseen by the law in force, the EN14781.
