note of caution; your galaxy may or may not have a nice springy fork. If you get a frameset with disc brakes and a steel fork, the chances are that the fork will be somewhat stiffer than a nice springy fork usually is.
So some folk notice that their nice new bike doesn't ride quite as well as their old one. Other times they don't notice and/or there isn't a big difference because the fork on the rim-braked bike was built strong/stiff anyway.
If you are concerned about this, try to ride old and prospective new bikes with similar tyres/pressures back to back and compare how they feel.
