The 3.0 is not a 126mm spacing that I'm aware of and mine certainly was not. Came with 7spd, upgraded to 8spd STI, then to 9spd STI. I would measure the rear spacing first, but I'm near positive that it is going to be 130mm. It is a great frameset. Remember they (Cannondale) tended to use the same frame for all its Road series line. $400 bike had the same frame as the $2000 bike of it time. Ride it and enjoy. If the urge to continue grabs you, then upgrade either the components or the bike.
