When you pick the bike up and spin a wheel with your hand, what happens?
Does the wheel quickly stop? If so, then the bearings are all gummed up
and need re-packing. But I can't imagine the guy at the LBS would not
point that out to you. How about the cranks; do they rotate freely? If
not, same thing.
A bike that has been sitting for years would need to have all the bearings
re-packed. Grease does not evaporate away quickly, but eventually it will
become a hard blob.
Are you sure nothing is rubbing? Those old brakes tend to have a habit of
being inconsistent. Sometimes they will center properly, and other times
they won't.
