“…Furthermore, rigorous test protocols must be implemented when taking measurements of the vibration transmitted to a cyclist [9]. Typically, four quantities have been used: acceleration [1-3, 7-10, 12-17, 20-24, 27], force [1,9,10,17,19], power [1,3,10,11,17,18,27], and energy [18,25,26]. These quantities are measured at or as close as possible to the cyclist's hands or buttocks to relate to what is experienced by the cyclist.…”
