it won't be worth your money to swap the cranks and stuff on it, if you wanted to do that you should have saved a little more and gotten a lighter frame to begin with...ie: motobecane, fuji track, pista...something like that...but since you have the dawes, i say just stick with that until you are ready to upgrade and then get a whole new bike(w/a lighter frame)...my friend has one of those and he loves it for what it is, but i just can't ever get over heavy that thing is.
