What to do... I'm just beginning to race for the school team and decided to upgrade my bike... Of course, I want to be competitive (meaning, I need the best of the best) but also, I need to be economical ( because being a high school student = I'm dead broke...)
I've narrowed my choices between the Devinci CX or Trek 2.3.
The Devinci CX is tiagra with a bunch of no-name parts, but is carbon...
Trek 2.3 is much better (105, bontrager lite) but is aluminum and much more expensive.
HELP PLEASE 
(PS: if there are any other bikes around this price range [lower than $2000] which have better performance, please do tell)
