all responses make sense. So we are all mostly saying the power output of the heavier riders might very well be greater than mine; but on hills my weight advantage takes over. ? I just always thought climbing hills to require far more effort and would more than offset power output on the flats.
I have been told to get stronger , I need do more sprinting. Maybe they have a more effective pedaling technique. ? Its odd though , because I ride far more than those heavier riders I refered to.
