Here is some background: I am currently riding alot. I ride a 30 year old trek 1000, with shifters on the down tube and all that stuff. I want to start racing more and after talking to a few people the logical next step for a new bike that is more realistic to race in is a $800 specialized allez (or something else in that price range). My dad thinks that i am being stupid and this new bike is worse than the 30 year old one I have now and the new one is too bad to even compete with and I will regret this decision if I buy it. He thinks I should wait a year and then buy a top of the line carbon bike. Remember I am only 16 and still growing. He thinks the $800 new bike will make me behind everyone else in my age group and I wont be able to compete. People at the bike shop think there is not much of a reason to put lots of money into the trek 1000 because it is old and I will need to upgrade soon anyway. So which direction should I go?

Any other bike suggestions are great too.
Thanks for any imput.
