Rear suspension for a bicycle which includes a rear swing arm (15) which carries the hub (19) of the rear wheel (20) and pivots via at least two pivot points (23,24) on a frame (1) carrying a bottom bracket (12). The swing arm (15) pivots about an instantaneous centre of rotation (25) located close to the stretch upper length of the chain (21), or to the straight line extending on from it, in a position of static equilibrium. The instantaneous centre of rotation moves inside a horizontal band (27) in such a way that the instantaneous centre of rotation (25) moves horizontally and forwards when the swing arm (15) moves upwards as the wheel goes over an obstacle. |
