Abstract: A rear fork for a bicycle, including a brake caliper support, mounted in rotation about the axle of the rear wheel and a hub carrier, fixed to the wheel axle, including a lower arm connected at a first end to the hub carrier and at a second end to the frame of the bicycle, and an upper arm, extending from the hub carrier to the frame. A connector link is arranged between the brake caliper and the lower arm, and the distance between the point of connection of the connector link on the lower arm and the connection of the lower arm to the hub carrier is at least equal to a third of the distance between the connection of the lower arm to the hub carrier and the connection of the lower arm to the frame.

Abstract: A rear suspension for a bicycle. A bottom fork is mounted pivotally at the bicycle frame bottom bracket and its other end is mounted at the top fork. The bottom fork bears a wheel which is driven in rotation by a chain. The top end of the top fork is pivotally mounted at the end of an arm, the other end of which is pivotably mounted to the frame. The vertices of the articulated quadrilateral defined by the top and bottom forks, the arm and the frame are arranged so that a straight line passing through the rear wheel hub rotation axis and the center of curvature of the hub path during the suspension travel forms an angle ranging between 10-° with the horizontal straight line extending parallel to the bicycle median longitudinal plane.
