Bike Fit Measurements

Hi

I have recently done an online bike fit calculator and the results are below.

Most of the figures make sense but I was wondering if anyone can explain how I set up the saddle-handlebar (where is this measured from) & saddle setback?

measurements are defined in this...

http://www.google.co.uk/url?sa=t&source ... NLR1YqywXw

but you should take the figures with several large pinches of salt...

for instance the figures it has given you have a 2cm range on saddle height, but even 5mm makes a big difference!

imho this is the fundamental measurement that everything else is built up from, so the calculator is really not telling you that much

a bike fit based on static measurement is not going to give the same results or benefits as a dynamic fit that takes into account any foot angle/arch issues, flexibility etc. etc.
