my steel frame bianchi is from the 80's and is all original and worth a good amount of money. I love it but it is not up to par with modern bikes, especially the handlebars for long rides. Being that I am a college student and don't have much money to spend on a nice bike, would it be better if I got newer components on my Bianchi as opposed to looking for a good used carbon fiber one such as an 2008 specialized tarmac for example?
