Sounds like you had a brake pad rubbing the wheel.
You should also get fitted to the bike and then ride it. You may have to readjust your fit as you get more miles on the road bike. This bike setup may have the bars too close to you. I know that when I needed to flip my stem down that I would get really sore in the shoulders because I was hunching them to make enough room for my arms, essentially. You should also have a saddle position as far forward as you can where you can just hold yourself up without falling on your face when you remove your hands from the bars (best to test this out on a trainer..haha). So find the part where you feel like you're going to tip and then move it back a smidge. A good place to start is by doing the knee over pedal spindle test, but based on your femur length and the geometry of the bike versus your build, this is only a general guideline. You shouldn't be using gobs of core strength while your hands are on the bars.
All of that said,
I LOVE my 54 Roubaix comp. 
Get fitted. Ride. If it's for you, then ride some more. Then get refitted as your road bike fitness and comfort level improves.
