They weren't as nice as, say, Clement Criterium, but they were better than the clinchers of the day (don't know how they'd compare now, but I bet they'd hold their own at least). The steel belt seemed to work for me, with very few flats, fewer than the Kevlar belted Clement Futuras, and much better than standard sewups (keeping in mind of course that the plural of anecdote isn't data). Rode better than the Futuras, too, IMO.
