ABSTRACT:
A bicycle pedal comprises a pedal body which contains a housing intended to accommodate a transverse spindle capable of being fixed to a crank. The pedal body is rotatably mounted on the said spindle by means of two rotary bearings provided respectively near the ends of the spindle. The rotary bearing provided at the end of the spindle remote from the crank comprises a needle bearing whose external diameter is smaller than the external diameter of the rotary bearing situated nearer the crank; the pedal body has a bearing surface for the user's foot which passes over the needle bearing, and is spaced from the geometrical axis of the spindle by a distance that is smaller than the external radial dimension of the pedal body in the vicinity of the rotary bearing nearer the crank. The bearing surface is a portion of a flat surface and extends as far as the external edge. This surface is situated towards the outside in relation to the rotary bearing near the crank.
