what are you trying to achieve?
a fast ride?
a leisurely ride?
neck ache?
or just enjoying yourself out on the bike?
1 of my bikes (expedition/off road tourer) is almost bolt upright. my mtb more forward but still plenty of room to move around and look around, my road bike, more aerodynamic and takes more to enjoy the scenery.
(now wait for everyone else to contradict me
