Abstract

Picture perfected for bicycles that are of those that incorporate two tubes in v that converge inferiorly in correspondence with the bottom bracket and that are directed respectively towards the posterior area of coupling of the saddle and towards the steering stem's articulation stem, to the once between said seatpost and the rear tube there is established a determining bar of a triangular structure for it, it is essentially characterized because this third bar, emerging from the seatpost, presents a first sector sharply inclined downwards and towards attracts, that after a obtuse and rounded bend extends into a second sector, substantially horizontal, which is coupled to the rear tube with notable distance from the upper end of the latter, having provided that the first sector of this bar ie the inclined sector, present an amplitude approximately equivalent to two thirds of its total length, than the second sector, the horizontal sector corresponds to the remaining third, that both sectors configure an obtuse angle of approximately 150º and that the second sector of such a bar is related to the rear tube of the frame at a point that is located approximately one third of its upper end and consequently to two thirds of the lower end corresponding to the bottom bracket.
