I have no idea what a 'quadrant' has to do with gear positions.
I thought maybe Jarred got it confused with 'sextant'. I also thought 'sextant' might have something to do with moving positions, but alas it does not.
I am at a loss to help. I sold my quad last year and sex is a fast fading memory. If I only knew what a 'tant' was, I could see how it relates to a 'rant'. Google is a marvelous invention..
