Your position can be adjusted later by:
1) either using a longer stem or a seatpost with extra set back or moving the seat back if you need extra reach.
or
2) a slightly shorter stem or a zero set back seat post or move the seat forward if top tube is a little bit too long
Given your inseam of 76cm and that cranks are normally on a small frame are 170mm (17cm) long,the 48cm seat post length , will give you about 10cm of seatpost extension which is about right, depending on what saddle, shoe or pedals you are going to use
I am fairly evenly distributed between torso and legs. I am, unfortunately, not long legged. The top tube lengths between the 48 and the 51 is 0.5cm, so I wonder if that difference matters?
I will probably use the stock saddle and pedals (
PD-5610 Road Clipless Pedals, according to the site) for a looooong time.
