It depends. I agree with the prior posters. In my case, I refurbished an '82 Univega Super Strada that my son-in-law was going to throw-out in the trash. The bike has all Shimano Dura Ace drivetrain including the odd "AX" series Dyna Drive pedals. The frame is solid with no rust or cracks. I considered it a learning experience to practice my bike mechanics on without too much worry about damaging a costly frame. I spent a fair amount of money on tools but I'll be able to use those on my other bikes or future bikes. For now, it's a fun bike to ride. I am considering converting it to 650B wheels and tires. Have to do some more measuring first.
