1) When you ride a road bike, should your upper
back/neck section be "concave", i.e.
just hang on the shoulders, or should it be
"convex", like an arc from one shoulder
to another?

2) Is there a technique to braking? When do you
use the left hand (the front brake), when
the right, and when both (save for an
emergency situation, I get that).
By instinct, it seems I use the front
much more. (Am I normal? )

3) What happens if you pedal slow, while the
bike moves fast? Do you contribute to the
speed just a tiny bit, but you don't notice
it, or perhaps it is a waste of effort
because of the construction, however
that works.

PS. Apologize for unclear language, typos etc.
No sleep or food 48+h. But who needs sleep
and food when there are bikes?
