I love the Ironman, but my 86 hates 28c Conti GP4000Sii. I've got about 1mm clearance btw the rear tire and the derailleur clamp, which would not suffice on gravel. I believe the Tempo would have more tire clearance. Perhaps add an older Trek sport tourer to your list as well. My 82 Trek 730 fits 28c with ease, and it's in the racing lineup. The sport touring models should get you to 32 and be sporty about it.
