Bicycle frame

A bicycle frame comprising:

• a seat tube, disposed at its upper end to receive a seat stay and arranged with a pedal bearing housing at its lower end,
• a pair of chain stays disposed essentially parallel to each other, rotatably joined respectively at their forward ends to a first pivot point arranged at said seat tube at a predetermined gap spacing to said pedal bearing housing and disposed above said pedal housing, and joined at their rearward ends to a contour for receiving of a rear wheel axis,
• a pair of seat stays disposed essentially parallel to each other, rotatably joined respectively at their first ends to a second pivot point arranged at said chain stay and disposed above the receiving of the rear wheel axis, whereby said second pivot point is disposed in the region of said contour,
• a rocker plate provided with three rocker plate pivot points, namely a first rocker plate pivot point at which a second end of said seat stay is respectively joined,
• a second rocker plate pivot point to which said seat tube is rotatably joined, and specifically in a region lying between said first pivot point and said seat tube upper end,
• a third rocker plate pivot point, flexibly connected to a first end of a spring damping arrangement arranged essentially parallel to said seat tube, whereby a second end of the spring damping arrangement is fixed on said frame,
• wherein the first pivot point as regards a reference plane of the pedal bearing axis and a fulcrum intersecting in the contour receiving the rear wheel, has in its stable condition, a measured gap of approximately 12 mm from the pedal bearing fulcrum parallel to said reference plane and a measured gap distance of approximately 38 mm vertical to this reference plane,
• wherein in said stable condition, the gap distance between said second pivot point to said pedal bearing axis amounts to approximately 413 mm parallel to said reference plane and approximately 47 mm vertical to said reference plane,
• wherein in said stable condition, the gap distance between said third pivot point and said first rocker plate pivot point to said pedal bearing axis parallel to said reference plane amounts to approximately 201 mm and approximately 300 mm vertical to said reference plane,
• wherein in said stable condition, the gap distance between said second rocker plate pivot point to said pedal bearing axis parallel to said reference plane amounts to approximately 86 mm and approximately 205 mm vertical to said reference plane, and
• wherein in said stable condition, the gap distance between said third rocker plate pivot point to said pedal bearing axis parallel to said reference plane amounts to approximately 19 mm in a direction counter to said rear wheel pivot point and approximately 110 mm vertical to said reference plane.
