Abstract
The invention relates to a bicycle frame (10), with a front part (11) defined by a head tube (1), a down tube (2), a top tube (3) and a strut tube (7) and a rear part (12) defined by the strut tube (7) and a set of tubes connecting to a rear wheel axle, usually a pair of seat stays (5) and a pair of chain stays (6). The frame also comprises a cantilevered seat tube (4), between an upper end (4a) and a lower end (4b). The seat tube (4) is connected to the strut tube (7), to the top tube (3) and to the seat stays (5). In the frame (10) of the invention, the top tube (3), the seat tube (4) and also the strut tube (7) and the seat stays (5) are connected to the lower end of the seat tube (4). This geometry is particularly advantageous for reducing the vertical stiffness and the bending stiffness of the seat tube (4).
