I don't know the proper names for the different handlebar options, but
I've ridden bikes where the handlebars are straight across, and the gear
shifts work well this way, and the ends of the handlebars don't hit my
legs. HOwever, that straight across, palms down position might not be
good for the wrists on long hauls.
I've ridden other bikes where the handlebars dropped on each end, like
this /=\, and twisting the gear shifters were not that comfortable, and
the handlebar ends could sometimes hit my legs.
Is there any option where the handlebar ends are like this /_\, where
the ends will not hit the legs, and the hands can be at an angle. Not
sure what this would do to the grip shifter ergonomics. Or possibility
of impaling yourself if you ever happened to go end over.
