[python] Re: Position of Steering Pivot Axis

Then, an other point in this question come: the angle between the pivot axis and the line middle hip joint-BB. 

Interesting idea. I will consider this in my experiments.

Last "speeking exemple" the "tt laurent 2" is now and since 3 month, my every day bike. Last week i loose my gloves... well... i do 95% of my way with my two hands in my pokets... through the city, and over a short climb around 12%. 

Sounds very good. Do you notice some PSI with this bike?

Laurent, I am always wondering about the low BB position
relative to the seat height of your bikes. Is this a constraint of
the frame geometry or just your personal taste?

It's to keep the angle pivot axis / line middle hip joint-BB close to 60° and in the same time have the trail angle not too sharp (for me 45° is too sharp) between 55 and 60°

If i put the BB higer, the angle pivot axis / line middle hip joint-BB come more open and the PSI come stronger

Is Pythonautes commes at the World chanpionship in france? http://www.ihpva.org/chapters/france/world2006/ Maybe a very good place too meet and exchange ideas. 

This year I plan to travel to the spezi fair at Germersheim in april.
Hope to meet some fellows there ...
In august I will be somewhere else.

Au revoir,
Jürgen.
