Thanks for all the input. I geuss I will try a 70mm. The frame was ok but I was getting front knee pain, to help this I put on a setback seat post to achieve Kops [I have Long legs short torso] this opened the frame up 20mm and made the reach feel long. The standover hight is perfect and the head tube lenght is about right at 16cm so a smaller frame would require 50mm's of headset spacers.

I was wondering the effect on slower or faster steering by useing a wider or narrower handlebar, say a 40cm VS 46cm. I know the width is subject to personal comfort and leverage in climes and sprints, but it would seem it could change handling characteristics like shorter and longer stems?
