Instrument-equipped bicycle component and detection unit for equipping such a component

An instrument-equipped bicycle component (1) comprises a detection unit (100a) of at least one parameter representative of a stress imparted upon the component (1), the component being a single piece or comprising more parts that do not move relative to one another. Preferably, the component is mobile with respect to the bicycle frame while the bicycle is travelling and the detection unit (100a) is intended to move as a single piece with the component (1) with respect to the bicycle frame. More preferably, the detected parameter is the torque applied by the cyclist to the aforementioned component (1) through the bicycle pedals.
