Indy, my 2010 Vita Comp has the following components:
Front derailleur-Shimano 105
Rear derailleur - Tiagra
Shifter - Tiagra
Crankset - Tiagra

The new 2011 Vita Comp componentry is not as nice (I can't get into the Specialized website right now, for some reason, to give the specifics), but then the price dropped from $1100 for the 2010 to $880 for the 2011.

Hope that helps.

Ciao
