Weight is important if you enjoy climbing and acceleration. Rider weight is most important. Rotational weight would be next in importance such as wheels.
If you enjoy riding over 13 mph, aerodynamics is important. Road cycling position is much more aerodynamic than an upright position. Reducing width can be better than reducing height.
