I rode a '80 Schwinn Traveler for most of the last season before selling it to someone who fit it better:

Thing was a tank, specs stated that it was 32lbs off the factory floor - and that was probably for one smaller than my monster 63cm frame. I rode it in my first Metric Century this past September. I've now moved on to a slightly ligher frame and have another yet lighter frame ready to be built up. All lugged steel.
