18 lbs is impressive. No matter how hard I tried, my old bikes of the mid 80s couldn't get under 19 lbs. with super light race wheels, Mavic GL 330 Double butted DT spokes with alloy nipples,3 X on the rear and 2 X in the front I was able to shave 4 onces off running Clement's Criterium Seta. The front would go our of true often, so I was really asking for trouble. Light and fast they were, but not all that durable. You are sticking to those large flange Campy hubs?
Hey that Ti Raleigh Ooze race heritage just as much. Look at Jan Rass and Hennie Kuiper putting the hurt on Moser in Rainbow and Joop Zoetemelk (winner of the Tour and he also rode for Ti Raleigh later). It doesn't get any better then that. These were huge stars of the sport. The men I only read about when I was a kid.
