Abstract: An aerodynamic assembly for bike handlebars, includes two distinct extension devices (4a, 4b), each of the two extension devices (4a, 4b) having: a first armrest-forming part (5a, 5b), able to be fastened on a transverse bar of a bike handlebars (1) while extending longitudinally forwards and including a longitudinal extension (6a, 6b) forming a free end portion. An upper surface of the first part with its longitudinal extension forming a receiving surface for a forearm part of a cyclist. A second extension-forming part (8a, 8b), able to be fastened, in a removable manner and in the extension of the first part (5a, 5b), to the free end portion, the second extension-forming part (8a, 8b) being able to slide longitudinally relative to said longitudinal extension (6a, 6b) so as to allow an adjustment of a distance separating a free end of the second extension-forming part (8a, 8b) from the first armrest-forming part (5a, 5b).

Abstract: A bike frame includes including a seat tube (10) for receiving a seatpost (2), a front portion comprising a top tube (13) connecting the seat tube (10) to a head tube (16), the seat tube (10), the top tube (13). The head tube (16) extends in a plane of symmetry of the bike frame (1). A rear portion has two chain stays (11a, 11b) and two seat stays (12a, 12b) arranged symmetrically relative to the plane of symmetry of the bike frame (1). The two seat stays (12a, 12b) are independent of each other and the two seat stays (12a, 12b) have a preform that is curved along at least one arc in a plane passing through the two seat stays, so as to enable the two seat stays to move away from or closer to each other under the action of a vertical load.

A rear portion has two chain stays (11a, 11b) and two seat stays (12a, 12b) arranged symmetrically relative to the plane of symmetry of the bike frame (1). Each seat stay (12a, 12b) has a perpendicular cross-sectional profile that is elongated in a direction parallel to the plane of symmetry. The two seat stays (12a, 12b) are independent of each other and the two seat stays (12a, 12b) have a preform that is curved along at least one arc in a plane passing through the two seat stays, so as to enable the two seat stays to move away from or closer to each other under the action of a vertical load.

Abstract: The device for securing a detachable cycle component, includes clamping elements including at least one clamping member (8) movable between a clamped position for securing the cycle component (1) and an unclamped position for releasing the cycle component, and tensioning elements (11, 12) acting on the clamping member for moving same toward the clamped and unclamped positions. The tensioning elements (11, 12) include a flexible element (11) connected to the clamping member, and a winding member (12) for winding the flexible element (11). This securing device may advantageously be used to secure a cycle component such as a seat post, a wheel or a handlebar to a cycle.
