I still haven't been professionally fitted so im not sure if "what feels right" is right for me so for now thats all I can do is determine by the height of that top tube. what I noticed as far as my body speaking to me on long rides is my finger tips go numb sometimes so i'm wondering if should raise the bars or am I stretched out too far.. Bike stores will only do a ballpark fitting IF I'm buying a bike from them and a Pro bike fitting that I found here with all great reviews is $300.00 with I think 2 or 3 hr sitting, standing, pedaling video and full documentation for me to take home but I have to wait till I get the spare cash.
