I found when I started riding more, my bike that had felt perfectly fine before all of a sudden started feeling cramped... A longer stem, lowering the handlebars and a bit of fiddling around gave me about an extra inch of reach - it's perfect again now!!! Suspect the same will happen with my new roadbike, it will feel quite stretched at the beginning compared to the mtb, but once I get used to the different position, it will be fine.
