I realize geometry is exceedingly important; it's just every time I buy a new bike or make a component change, I really don't feel any different... well, except for the new short reach bars and brifters. There isn't anything unusual about my arms and legs in terms of length of femurs, etc. I am in proportion for my size.
The person who fit me is one of the best in the state. It's true that he may not know everything about fitting a petite sized woman, but there are lots of other women my size who are very happy with their purchases from him. I guess next time I could go custom for about the same money as I spent on my current bike. Seven is right down the road.
In the mean time, I will keep working on my core. Despite my complaining, I have improved my skills a lot.
