Yeah, but what I meant is a good vintage bike won't cost you much money. Take the money you're going to spend on the bottom bracket and chainrings, and put it into a good vintage bike. Then you'll have something worth whatever money you put into it.

The Huffy isn't worth the time and money you'll spend on upgrades. Ride it until you buy something better, then sell the Huffy for the same $20 you paid, and upgrade your good bike.
