Abstract
Detectors consisting of electric strain gages placed on one end of a bicycle wheel spindle and incorporated in the wheel hub are connected to an electric circuit which includes an apparatus for indicating the value of torque transmitted by the wheel. The strain gages can be influenced only by variations in the force applied to the spindle end in the horizontal plane which passes through the center of the spindle. There is thus measured only the horizontal component of the shearing force applied to the wheel spindle, from which it is possible to deduce the value of torque transmitted to the wheel. Instead of being fixed directly on one end of the wheel spindle, the strain gages can be fixed on a member which is associated with the spindle end, the member being capable of bending or undergoing deformation in the horizontal plane which passes through the center of the wheel spindle.
