Abstract: A pedal includes a pedal body (1) mounted rotatably on a pedal axle (2) and having at least two arches (7) for engaging an engagement member (8) fixed below a cyclist's shoe. The arches have opposite branches connected to the pedal body and they are disposed one after the other about the periphery of the pedal body (1) so as to define between them an engagement surface for the engagement member (8) against the pedal body (1). The two arches (7) are adapted to be urged toward each other by resilient return elements returning them to a retention position for the engagement member (8). At least one of the at least two arches is a resilient arch constituting the resilient return elements, and the ends of this resilient arch have bending axes that are offset relative to each other.

Abstract: The frame includes at its rear portion two bases (12, 13) extending substantially horizontally rearwardly so as to define between them a space for the reception of a rear wheel, and two stays (14, 15) extending obliquely toward one respective end of the bases (12, 13) and being connected thereto at an acute angle by connection elements, a pair of recesses for a rear wheel axle being disposed substantially at the intersection of the stays (14, 15) with the bases (12, 13) . Each recess of the pair of recesses has a first notch with a semicircular bottom (23) provided at one flattened end of a base and a second notch with a semicircular bottom (24) provided at a flattened end of a stay and disposed facing the first notch (23) such that the semicircular bottoms will be aligned with each other.

Abstract: The pedal comprises a pedal body (2) mounted rotatably on a pedal axle (3) and provided with a retainer (7 to 10) of an engagement member fixed below a bicycle shoe, the retainer (7 to 10) comprising a first pair of arches (7, 8) mounted fixedly and a second pair of arches (9, 10) mounted pivoting between the fixed arches (7, 8). A resilient return (12, 13) acts on the pivoting arches (9, 10) to urge them toward a position of retaining the engagement member between a fixed arch (7, 8) and a pivoting arch (9, 10) following relative angular spacing apart of these latter by said engagement member against the action of the resilient return (12, 13). The pivotal axis of each pivoting arch (9, 10) is eccentric to the axis of rotation (A-A) of the pedal axle (3).

Abstract: The steering set comprises an upper roller bearing (2) and a lower roller bearing (18) adapted to guide in rotation a pivot tube. Each roller bearing is (2, 18) received in a respective annular recess (14, 19) provided within a steering post (11) forming a part of a bicycle frame (12). Each roller bearing (2, 18) is associated with a respective ring (3, 24) itself resting on a support surface, and an end ring (6) surrounded the pivot tube (10) above the steering socket (11). The roller bearings (2, 18) are associated with adapters (26, 27) in the form of rings disposed between the roller bearings (2, 18) and the bottom of the annular recess (14, 19) so as to adjust the height of the recess so as to adapt it to roller bearings (2, 18) having different heights.

Abstract: The invention relates to a front fork (10) for cycles, made of composite material, comprising two fork arms (12, 14) which unite to form an upper fork head (18). The fork head (18) comprises two rearwardly directed projections, an upper projection (30) and a lower projection (28). The two projections carry pivot portions (36, 38) which cooperate with complementary pivot portions (32, 34) provided on the steering head (24) of the frame. The fork arms (12, 14) are formed substantially linear and their centrelines are arranged at least generally in a plane in which the centreline of the fork head (18) also extends. This plane is located forwardly of the steering axis (YY) at a distance which depends on the dimensions of the cycle and is suitable to ensure the stability of the cycle.

Abstract: An apparatus for securing elements to the wall of composite components has a holder which passes through an aperture of the composite component. The holder consists of a coupling part which is disposed on the side of the composite component to which access is difficult and also of an operating part which is disposed at the readily accessible side of the composite component. The actuating part and the coupling part are engagable with one another for the application of a rotary movement from the actuating part to the coupling part. The coupling part is couplable with a coupling counterpart of the element to be mounted which passes through the actuating part through mutual rotation and axial clamping of the coupling part, the wall, the actuating part and the element.
