1982-83 Schwinn Prelude worth upgrading?
I’ve been shopping for a bike for quite some time now, ideally a gravel/cyclocross bike, but have yet to come across anything in my size or budget so I’m considering buying something older and building what I want out of it. I came across a 1982-83 Schwinn Prelude in excellent condition and was wondering if some upgrades are possible for the bike. To start, I’d like to just throw some knobby, larger tires on it, would it be possible for the bike to fit them? Or will I have to stick with normal road bike tires? In the long run I’d like to install some new handlebars to make the bike feel a bit more modern, what does the process of that entail? And is this all worth it for an older bike? Sorry for the odd question, new to bikes and upgrading them. I wish I could upload images as well but this is my first post so I can’t.
