Possible new (maybe not so new) reason for sluggish handling on shallow head tube angled bikes...

After listening, or reading rather, to Dapper Dan and Slowman's conversation on another thread about sizeable stem drops and the effect or null effect this has on a bicycle's handling, I got to a thinkin' (warning: this could mean trouble ;) ). So here's what I came up with:
  • If you take a bicycle with a 73 degree head tube angle and a 0 degree rise stem and turn the handlebars 90 degrees so that the front wheel is perpendicular to the frame------ the handlebars (following the axis of the head tube when turning) will drop 17 degrees.

and
  • If you take a bicycle with a 70 degree head tube angle and a 0 degree rise stem and turn the handlebars 90 degrees so that the front wheel is perpendicular to the frame------ the handlebars (following the axis of the head tube when turning) will drop 20 degrees.

Considering that the front end of a bike (a tri bike in particular) weighs alot, could this natural pull (gravity) have a significant influence on why a bike with a shallow head tube angle resists quick turning?- (all turns consist of an initial move in the opposite direction and a counter turn once the weight of the rider is going the right direction)

Discuss if you're interested, don't care, or if you have already thought of this.
Thanks,

Jeff
