[python] Re: New Python - 20" or 26"?

 
Hello again
 
Thank you for your comments. Very helpfull.
Dirk, you are right, I was thinking on 5 mts full turn, 2,5 mts radius... my 
mistake and my bad english. :). Anyway, very good news for me.
Jürgen, my inseam height is about 84 cm, wich I suppose will be enough to a 26" 
front... well, at least it works for a thinner, low profile tire (1"95), bus I 
want to use a "fat" one (2"0 low pressure). Why? because "Smooth road" is 
almost an unknown concept in Portugal... Sometimes it would be better riding 
off-road. A set of 20" wheels (as I have on my trike) can be very uncomfortable 
above 30 Kmts/h, I think a set of 26" ones will be much better, as I want to 
build a rigid frame.
The measures I've been taking yesterday were not conclusive; I'm afraid I will 
have to raise the BB about 2"or so to use a 26" front - Is it possible without 
compromising the overall performance (stability)? I suppose there must be some 
kind of relationship between the horizontal distance between the pivot, contact 
path and BB. I just don't want to use a 24" front because in Portugal there are 
very few tire types to choose to this size.
 
One question: how faster a python can be? (average and top speed). And did 
anyone found any relation between the total weight (bike+rider) and the maximum 
speed? 
 
 
Thank you very much,
 
Jaime Alexandre
