Subject says it all-- love my vintage steel frames but not a fan of vintage component setups. Levers aren't comfortable to me since "riding the hoods" didn't seem to be as popular as it is today (??). Brake calipers don't stop as quickly as a modern cheapo Tektro double-pivot set. I'm not a fan of downtube shifters. Double + 12-21 cassette? Not a chance.
Yet here I have a chance to buy an early 80s Campy Super Record groupset for < $400 to outfit an early 80s Gios frame I already have, but I think I'm going to pass in favor of a modern groupset...so am I crazy?
