The measurements do not include comfort or ability of Bram. The SRM measures the power input on the cranks. http://www.srm.de/usa/prod_srmts_subhome.html So the human element is cut away from the experiment. The experiments do not say if Bram enjoyed pedalling at 200W ;-). > So when there is no big difference between 15 and 25 cm BB height, > then this may relate to Bram Moens personal shape. It is more comfortable to have the BB low. If you lower the BB below 15cms you come into the wind flowing under your seat.
