Abstract: The present invention relates to a wheel with a pressure regulator and to the applicable rim. The wheel has a tire (4) with a main leak-tight chamber (2) connected to an inflation valve (5) and a rim (3). There is arranged in the rim (3) a tunnel (1) forming a leak-tight chamber with gas under high pressure, connected to the main chamber (2) through a manual or automatic regulating valve (6). The regulating valve (6) and the inflation valve (5) can correspond to a two- or three-position valve. The rim therefore includes a leak-tight tunnel (1) therein, with a valve for filling the tunnel (1) oriented towards the outside (13) of the rim (3) and a regulating valve (6) oriented towards the channel (8) for placement of the tire (4).

Abstract: The present invention relates to a suspension system for bicycles or other similar vehicles, said suspension system comprising a main triangle (1) or frame connected at one end to a front wheel (6) and connected at the other end to a damper (2) and a swinging element (3) serving as support means of a rear wheel (7); and wherein it incorporates a lower connecting element (5) comprising a first connecting shaft or point (5a) connected to the main triangle (1) and a connecting shaft or point (5b) connected to the swinging element (3), and where said system incorporates an upper connecting element (4) where there is located the first connecting shaft or point (4a) connected to the main triangle (1) and another second connecting shaft or point (4b) connected to the swinging element (3) and the damper (2).
