Another thing we need to consider here, is the speed held through turns. If you are riding at say 15mph or less through 90 degree turns, I don't think you can talk much about handling characteristics between one type or the other. I ride tubulars on my vintage bikes, and clinchers on my modern bikes ... not by choice specifically, but by default .. as in, that's what was on the bike (or in the case of vintage restorations, what I have deemed appropriate for the bike). The tubulars are inflated to about 115psi, and the clinchers to about 110psi. I also like to ride hard and fast, and I love screaming through turns. Thinking about it now, I guess I can admit that my vintage bikes, namely my 84 Torpado Superlight that is used most oft, give me a little bit more secure feeling in the high speed turns, compared to the slick tread, carbon reinforced clinchers on my two modern bikes. However, I had yet to try out inflating the clinchers only to 100psi, as has been suggested many times here, and by local people more experienced than I. Just recently though, I went on a "modern" ride, but forgot to top off the tires to my normal 110psi. Having just ridden the same bike a couple day before, I would guess that the pressure was closer to 100psi. Again, I have to admit that the bike felt more stable through turns than before, with less harsh bounce or rattling, but I have yet to try it through one of the real zigzag, criterium type sections that we often ride though. You can bet that I'm going to try it next time. FYI, I finally looked down at my computer on my modern bike while doing this a few days ago, and noticed that I was traveling at 24.5mph ... FUN STUFF! List member Tom Dusky has been with me in these sections, and can probably affirm that I do really try to fly through them. Also, as I noted above, my clinchers are smooth tread, and so it might be harder to compare them, to the kind of tiny bump made cross-hatch tread on Continental Sprinter tubulars, for example. That notwithstanding, I think the real point of my post is that the difference might only be felt when in a genuine high speed turn, not by cruising easy around a couple of turns. At least I don't notice any difference at low speeds. Kind of like comparing the acceleration of a Corvette to a Chevette ... when traveling through a 15mph parking lot. There just isn't much of any real test there, with which to compare. Oh, and then there is the concept of accelerating through turns, leaning your body in while trying to keep the bike more upright to help maintain grip. But that is likely something that not many on the list do, I'm guessing. Flame me not please, I'm just reporting it as I experience it. But I'll try to write again about the subject, when I've run the clinchers at 100psi, hard through some real fast turns.

Their ride is really nice, they corner and grip beautifully and considerably better than the cheaper heavier type tubs... Their rolling resistance was not on par with the Clement Crit tubs or Veloflex tubs tested at the same time but you are talking about the best of the best with those... And these were real road rolling resistance tests - not done on a drum or lab but tested properly in repeatable tests on real road...However the tubeless tyres which are now beginning to be available will outperform tubs...Hilary Stone, Bristol, British IslesEmilio Bozzi wrote:> RE:> Veloflex clinchers were then steets ahead of other clinchers> and /_close in performance _/to the best tubulars {underline edit}> > Hilary, thanks for your response, and one that is a very noble and > common refrain.> Please don't feel that I am singling you out, as I am not, but I have > lost count of how many times I have heard that modern clinchers ride > "just as good as" or "almost just as good as any sew-up".> > Allow me to pose a simple question to CR listers and ask them how many > time they have heard just the opposite:> "I really like these sew-ups they ride just as good as clinchers!"> I sure as heck have never heard anyone say that.> And there is an obvious simple reason:> Clinchers have never ridden, handled or performed as good any sew-ups in > my experience, ever.> > Those folks that have changed out their beautiful steeds OEM with > sew-ups for those bizarre clincher contraptions---and you know who you > are---should be shot at dawn!
