Abstract

See full text

A bicycle includes a frame, a rear wheel, a suspension system that allows a predetermined relative movement therebetween, and a drivetrain system. The drivetrain system includes a crankset fixed to the frame, a hub and pinion assembly fixed to the rear wheel rotatable about a common pivot axis thereof, and a drive chain placed to connect them directly to each other. The crankset and the hub and pinion assembly are subjected to mutual movement by the action of the suspension system, where at least one among the crankset and the hub and pinion assembly includes a free stroke device that allows both an outbound and inbound free angular stroke of the chain with respect to the respective pivot axes of the crankset and/or of the hub and pinion assembly. The angular stroke is limited by a predetermined angle of entity related to the movement between the wheel and frame.
