I have an '03 Masi Gran Corsa that I have only had for roughly five months. After taking it down off of the wall at work to throw some air in the tyres, I noticed that I have what looks like some small cracks on the left side of my b/b shell and a stress fracture near the bottom of the down tube.

Should I be worried about this, or am I just jumping to conclusions? I did break my CAD2 mtn. frame this summer (if it matters). This is my first road bike and I have only put maybe 200 miles on it so far.
