|I'm just wondering what the deal is with tubular tires...I've actually never installed or ridden them so very limited to their performance/ease of use. I do know though that most of the pro's still ride tubulars even though clinchers have caught up significantly in the last few year, but I don't understand there reasoning.
I just sold my pair of Michelin Axial Pro's and purchased Vittoria Open Corsa CX T.T PRB's...and love them in comparison to Axial's. I have them on a Seistriere wheelset. But I noticed that the tubular version (Corsa CX TT PRB) are available...and supposedly used by the best of the best. What's the reasoning for this? My Open Corsa's weigh less than the Corsa tubulars and can be pumped up to a more than satisfactory 120psi. And I hear tubulars pop quite easily...why is this? Does one actually use a tube to inflate a tubular tire, or is the tire itself inflating onto the rim? Please clarify this...I'm confused.
Sorry for complete newbiesm...just never looked into this before :)

|The comparisson of tubular to clincher isn't all that clear cut. Depends on the tire. With the advent of Kevlar beads, the clinchers have become lighter, but in general a tubular RIM will be lighter than its clincher counterpart. It's the combination that you need to look at. A tubular tire has a tub sewn into the tire, with a seam hidden under the base tape (thus the name sew-up). Because of the roundness of the tire cross section, there is a noticeable difference in the "suppleness" of the tire, and a consistent feel in corners (clinchers tend to have distinct ranges of feel depending on lean angle). The failure rate of tubulars isn't any higher than clinchers for comparable tires. I think what happens is that the more weight conscious riders are using tubulars, and taking it to the limit with lighter tires, which are more prone to punctures. Unless you get some good practice gluing tires onto rims with a knowledgeable person looking on, I'd stay with clinchers. A rolled tire in a corner is no fun, even when it's not yours (like the guy on your inside going into a tight roundabout).|

|The reason why your Corsa Clincher weighs less than a Corsa tubular is becase the tubular includes the tube (hence, the name, 'tubular'). Weigh your Corsa with a latex tube (like the ones that are inside a Corsa tubular, and it will weigh more, guaranteed. Of course, few clincher owners actually use latex tubes, so a butyl tube will add even more to the weight.
Of course you haven't installed a tubular tire, and, unless you own a wheel with tubular rims, you wouldn't. Tubular tires don't work on clincher rims.
The reasons why the pros use tubulars are basically these two: First, tubular tires AND RIMS, as a complete package, weigh les, and that weight reduction at the rim results in faster acceleration. Second, tubular tires have the capability of accepting higher pressures (as much as 225 psig in some cases, 175psig for Corsas), yet can also be run at pressures well below 100psig without risking pinch-flats. The ride from tubulars is also better, but that is not a big advantage in racing.
I don't know where you heard that tubulars "pop quite easily" (whatever the hell that means). My experience with GOOD tubulars has been that they are actually more durable than clinchers.
To inflate a tubular, you use a pump, just like any other tire in the world. I'm confused as to what you are asking on this one.

|Tubulars go on rims made for tubulars, clinchers go on rims made for clinchers. You cannot mount one kind of tire on the other kind of rim.
A tubular tire is a complete unit, tire sewn around the tube, and that tire/tube combination is glued to the rim. So your question of "Does one actually use a tube to inflate a tubular tire, or is the tire itself inflating onto the rim" makes no sense.

"Does one actually use a tube to inflate a tubular tire, or is the tire itself inflating onto the rim?"
shows that there's some confusion out there between tubular and tubeless tires. It's understable, given how similar the words sound.

|Actually, Tufo made a tubular tire that could be mounted on a clincher rim (seems like the worst of both worlds). It had a pretty stiff rubber "base tape" that extended beyond the tire and would snap in under the hooks of the rim. Never used them, don't know any one who did. Don't know about their reliablilty.|

|Hey guys...thanks for clearing that up. I was indeed confused (been told more than one version of "what a tubular tire consists of?" from several buddies. Sorry for the incoherent questions about there physical attributes...simply did not have the proper background.
I'm happy with the Open Corsa clincher's, and will stick with them for now. If I get a good deal on some tubular Zipp 303 rims, I may jump the boat just to give the "tubular" world a whirl. A friend of mine races with these and says he see's them in "many" races. I'm embarking on the world of racing now (been a casual triathlete for a while and to be honest with you I never really paid attention to components...just went on recommendations). And you know us tri-athletes...we are nuts over our physical condition rather than over bike condition :) This is all changing though...I've caught the cycling technology/component frenzy bug.
Thanks again. Check out my thread on the 3T Zepp XL...any one using these handlebar/stem matchup? LMK.
