In reply to Phil1919:
How far is too far away? I was professionally fitted to my new road bike and it does make a difference.
This frame is a 58cm. I could be a 60 or 56 on a different geometry bike. I am 6'2" ona good day, inside leg 33".
You take take a gamble that pays off, or you could be p1ssing about with seat post and stems for ever!
A mate told me when I was looking at a bike online that 'would I buy a pair of walking boots without trying them on...?' I took her advice.
Hace you got a bike shop locally or a mate with a bike you could sit on and try?
I got the Specialized Sectuer Elite Sport.
Cheers and Good Luck!
