|I need to replace my vittoria corsa cx tire on my rear shamal - what do people recommend? I have very little tubular experience.
I've heard that Veloflex criteriums are made in the old Vittoria factory and that they are much better quality than current Vittorias. I found one for shipped for about $60 compared to a vittoria for $45- is it worth the difference?
On the Continental side - I've heard that they are slightly stiffer tires than vittoria/veloflex which I can believe based on experience with their clinchers. The Sprinter seems to be the most common model purchased. I can't find much information about the super-expensive Competition, except it seems to be a bit more puncture proof and lighter than the Sprinter. I found the Competition for $60-65, compared to a Sprinter for $40? What do I gain?
I use the Shamals for most road races (except super steep courses), time trials, and a few crits. Rolling resistance, grip/handling, and comfort are my priorities, followed by longetivity and puncture resistance. It looks like the Sprinters may be the best bang for the money. In any case, I'm itching to try something other than the Vittorias which I'm not terribly impressed with. What are you using and why? Thanks.

|Tubular spec's attached re-Conti. Sprinter's and Competition's.
The Sprinter's are a good economical racing tub, but the extra £$£$££$ is worth spending on the Competition's, which offer a diffrenet ride altogether over the Sprinter's, hence the reason a lot of pro's ride them, they have the lowest rolling resistance available in ANY tyre!!, speaks for itself.
Weight differences, are:-)
Competition 27" - 19mm @ 240g, max. pressure 170 psi
Competition 27" - 22mm @ 275g, same max. pressure as per 19mm
Sprinter 27" - 22mm @ 275g, same max. pressure as per Competition's.
other than that, you get more colour options with the Comp's over the Sprinter's.
Hope this helps.

|An S3 lite, weighing in at 190g (not thicj=k enogh for everyday use), and one that weighs 215 grams.
The S33 special (their heavy-duty road-training tire) weighs only 240 g, and even the bare-bones cheap S22 weighs 260 g. Oh, BTW, they are round, too.

|I don't know this for a fact, but I have heard, that Tufo's are light, but slow. That is, that they have more rolling resistance than normal sew ups, because of their special construction.
I would be interested in hearing from other Tufo users because I've got one sitting on a rim that I was thinking of using this year.

|The hard rubber of the Special line has almost zero rolling resistance (but not much grip, either). The S22 has a bit more resistance, but less than, say, a Sprinter.|

|You may be confusing the Tufo "clinchular" with their regular tires. The clinchular is a tubular with a molded bead on the casing so that it can be installed on a clincher rim. By many reports, the worst of both worlds. Their regular tubulars are built pretty much the same as any other.|

|Firstly, I DO know the difference between tubulars and those awful clinch-tubo things. I'm even old enough to remember when Clement first tried (and failed) to make such tires.
No, Tufo's are NOT just like any other tubular. There is no thread holding the carcass together, rather, it is bonded together. There is a liner inside, but it does not meet the criteria to be called a tube. Tufos are completely different from any other tubulars-that's why they are cheaper, rounder, and lighter than anything in their field.

|They have high rolling resistance...||terzo rene|

|and they ride like absolute crap. The worst ride quality of any tubular I have ever tried, and it was the top of the line Elite model too. I quickly switched to Veloflex Criteriums and it was blessed relief.
I can't find the link to the rolling resistance study but they were definitely worse than other tubbies. They felt it too. I lot of people seem to love Tufo but I can only think they have never ridden a quality tubular. They do make wonderful valve extenders however which I highly recommend.
