Abstract: A bicycle wheel carrier assembly is equipped with a rim brake with pads (5) which is built into the structure of the carrier assembly. The rim brake includes two actuating arms (3) and two pad-bearing brake arms (4). Each actuating arm (3) associated with a pad-bearing brake arm (4) is articulated in a recess of the structure of the carrier assembly between a first position in which it is retracted within the structure and a second position providing access to the pad-bearing brake arm (4).

Abstract: The stem (1) is provided with elements (3) for attaching the stem to the upper end of a pivoting tube and elements (25) for attaching a handlebar to the stem. The rear attachment elements (3) include articulation members (8) that make it possible to adjust the tilt of the stem (1) and tightening elements (10, 11, 19, 21) that make it possible to lock the stem in an angular position. The tightening elements are of a semi-cylindrical shape extending crosswise into a housing (12) that has an opening (12?) downward that makes it possible to insert the pivoting tube (4). The tightening elements at their upper and lower ends are provided with a receiving recess (13, 14) that is adapted to the pivoting tube and extend crosswise in the housing that has a cylindrical wall (15) cooperating with the first tightening element (10) so as to define the articulation members.

Abstract: A bicycle wheel carrier assembly is equipped with a rim brake with pads (5) which is built into the structure of the carrier assembly. The pad-type rim brake includes two actuating arms (3) and two pad-bearing brake arms (4). Each actuating arm (3) associated with a pad-bearing brake arm (4) is articulated in a recess of the structure of the carrier assembly between a first position in which it is retracted within the structure and a second position providing access to the pad-bearing brake arm (4).

Abstract: A bicycle stem includes a stem body (2) that is provided with first elements (3) adapted to attach the bicycle stem to a pivoting tube and second elements (25) adapted to attach a handlebar to the stem. The handlebar include a U-shaped cap (27) that has first connecting elements (32) that connect to second connecting elements (33) that are provided at the front end of the stem body (2) to attach the U-shaped cap (27) opposite a recess (30) provided on the front end of the stem body to receive the handlebar. The length of the stem can be modified using a crescent-shaped spacer (35) that is placed in a U shape for obtaining a reduced length of the stem or in the recess (30) to obtain a more significant length.

The latter include a U-shaped cap (27) that has first connecting elements (32) that are able to be connected to the second connecting elements (33) that are provided at the front end of the stem body (2) to attach the U-shaped cap (27) opposite a recess (30) that is provided on the front end of the stem body to receive the handlebar. The length of the stem can be modified using at least one crescent-shaped spacer (35) that is placed in the shape of a U for obtaining a reduced length of the stem or in the recess (30) for obtaining a more significant length.
