Check out sport touring bicycles (i.e. the Marinoni Ciclo) or Audax or Randonneuring bicycles ... check Thorn, Rivendell, etc. They are a cross between a racing bicycle and a touring bicycle and can handle carrying some gear, but in general they're a little lighter and "faster" than a traditional touring bicycle.

Waterford might be another option: http://www.waterfordbikes.com/site/designs/st.php
