A novel dynamometric hubset design to measure wheel loads in road cycling

The aim of this research is to develop a dynamometric road bicycle hubset to enable wheel load measurements while correctly taking into account the end support conditions of the axles. A new hubset design is proposed, providing a way to measure vertical and horizontal forces at each end of the hub axles and to obtain all the ground contact loads acting on the bicycle wheels while pedalling or coasting. This paper presents results for ground contact loads when climbing out of the saddle and for road impact at the wheels.
