Welcome to the world of "Cannondale"!
I was in the LBS yesterday after hearing a creaking sound while going up large hills on my ride and thought it was in my cranks but turned out to be a loose headset. Anyway I saw that the newer 105 are black in color, anodized? I was thinking why couldn't mine be like that. I have a 2009 model but they told me that the newer 1/2 year models started coming with the black color. Man I thought it was sweet looking.
Actually started thinking of getting it but then said if I upgrade it will be to Dura-ace.
