 Such linkages allow the progressivity of the suspension to be optimized.Single pivot bikes in which the shock is directly connected to the rear triangle, while taking advantage of the simplicity of the design, create a regressive suspension rate, which depending on the type of riding and the force of the impacts, may not be optimal.An advantage of a classic single pivot bike in comparison with a four-bar single or multiple pivot design is the rigidity that it’s possible to attain with a single structure that’s connecting the rear wheel to the frame.
