Ive been reading posts about how recumbent are slower on the hills by all the upright riders out there... its true they can be slower on the hills but the uprights refuse to admit how much more aero they are .....I've passed many a paceline on my recumbent.... it seems upright riders can't achieve any real speed or distance solo because of the grossly un aero riding position they ride in.. uprights are better on the hills but recumbent are better on the rest of the road
