they are awesome tires. i have the master 22s and the paves (which was what it was called previously.) both measure pretty much 22mm+ maybe a touch over. they feel as close to tubulars as any clincher tire i've ever tried. of course, not as rugged as say a gatorskin, but that's the tradeoff that you make for a nice supple ride. handmade in italy still. i don't think you'll be disappointed in veloflex. i've also tried the challenge criterium gum wall tires and they don't even come close to veloflex.
