Got a Zzipper 'thriller' Fairing for a bike setup i was doing a 12 mile commute.
the aerodynamics was the airflow around a smooth frontal ..
It wasn't really a Low crouch..
a benefit I didnt have to dress so warmly, since the airflow was less through my clothing..
It was a river bottom road so pretty flat.. the Fairing also made the audio on my Books on tape
hearing easier to fill the hour..
