okay, I'd like to get a new road bike. I currently have a trek 1000. I want to race, most likely crits. I'm about 5'3 1/2. I've looked at specialized's allez and others. does anyone race on these? I have no more than $1200 i can spend on this bike. I'm thinking of buying the specialized cr-mo allez frame and then buliding it with shimano 105.
