I considered using a small rear wheel for a long time (you can find that in the archives) but in the end I chose for a 26" wheel mainly for compatibility - I would use it in foreign countries every year, and not all countries sell all tire sizes. 26" is the most common one and I don't want to be carrying around 2 spare tires every time I ride for a longer time. I definitely agree though that if you use your python for local use, you're much better off with a small rear wheel - what you say, a shorter python, but you can also use a shorter wheelbase (basically more agile). A 20" wheel is much stiffer than a 26" wheel, so in an unsuspended bike it might be quite uncomfortable. Sam On 11/11/05, 25hz <25hz@xxxxxxxxxx> wrote: > Very cool.
