It's probably fit then as I have to lean over further on the new bike, I might need a longer stem to be more like my Lemond. But 2.5cm is one inch difference so I am not sure but I will ride it and see if it gets better. However, I can reach 34.mph down the slight hill near my house on old bike and can only get the new bike up to 30.9 so it could be my pedal stroke.
