Abstract
A torque sensing arrangement has a set of strain sensors, such as strain gauges, mounted to an adapter that can be mounted to a chain ring of the crank set of a bicycle wheel. The adapter may have an annular body that can be used to retrofit the original crank set of a bicycle to have torque sensing components without having to replace the chain rings or the crank arm of the crank set. Together with angular velocity measurements, the measurements of the strain sensors may be used to calculate the amount of work or power exerted by the cyclist to propel the bicycle.
