Subject: RE: Tufo tubular clinchers Well I have actually heard 120 pounds is optimal for speed. Actually making the tires hold more pressure will make the tire harder and hit bumps with a harder blow which actually slows you down rather than speeds you up. I am sure on certain terrian a higher pressure might be better but for most terrian 120 is optimal. I ride vittoria clinchers that are like the tufo tubulars adn I love them. I actually need to buy a new set. Anyway I work at a shop as well and have heard from numerouse people that 120 is the best pressure to run and I have read an article online somewhere that has done a test proving this.
