Sure I do. Maintenance and expense.<br />
<br />
Tubeless brings several advantages:<br />
<br />
- easy to change a tire<br />
- lots of tire choices, and even the good ones are comparatively inexpensive.<br />
- no pinch flats<br />
- FAST mounting<br />
- flat protection with sealant (just like you'd get with Tufo tubies)<br />
<br />
For me, the biggie was speed of tire replacement. Whenever I flatted or rolled a tubular, I had to peel it off, clean the rim, and then spend at least a couple days gluing it. The maintenance sucks, so I'd take…

For me, the biggie was speed of tire replacement. Whenever I flatted or rolled a tubular, I had to peel it off, clean the rim, and then spend at least a couple days gluing it. The maintenance sucks, so I'd take shortcuts, and I'd roll a tire because of it.<br />
<br />
And how much does a new Fango cost? More than a quality clincher tire. And if you flat, do you need to buy another? That adds up, too.<br />
<br />
I've ridden tubulars (I used Tufos with sealant), and I loved them, but the maintenance time and added expense lead me to push things longer than I should have.<br />
<br />
If you have the time to maintain them, and the budget to replace them when they should be replaced, go for it. Otherwise, I'd at least consider a tubeless setup.

I run Grifos and have experienced the valve core base leaking with a few of them, but am wondering what you do to prevent it? I also run Grifo's on deep (404) rims with valve extenders (aluminum screw-in type). Is there any thing I can do to prevent leakage at the valve base? (I assume I'd have to do it before gluing & mounting).<br />
<br />
Any tips appreciated!<br />

Bishop rolled it because he hadn't checked the glue job since gluing them last year. That's a direct quote. Bishop does not have the best reputation for maintaining his own equipment, cf the recent VeloNews interview with him.

Something to consider for a larger rider and tubulars is the method you use to glue the tubular. This weekend two super experienced riders, Myerson and Bishop rolled tires at different courses, but similar scenarios. Sharp off camber corners while accelerating. These guys have glued more tubulars in their days than most bike shops ever, and Myerson is OCD about his equipment. So, when you get into the first timers gluing, remember a few things:<br />

Something to consider for a larger rider and tubulars is the method you use to glue the tubular. This weekend two super experienced riders, Myerson and Bishop rolled tires at different courses, but similar scenarios. Sharp off camber corners while accelerating. These guys have glued more tubulars in their days than most bike shops ever, and Myerson is OCD about his equipment. So, when you get into the first timers gluing, remember a few things:<br />
<br />
1) Consider the shape of the tubular bed on the wheel and the profile of the tire. Challenges have a slightly flatter bottom to them than something like a Tufo Flexus. The "glue and tape" method is a better set up on the Challenges while you can get away with just glue on the Tufo.<br />
<br />
2) All wheels are tires are not the same- especially when you are getting into the cotton or silk tires. Deflection is normal for these tires- even if its super subtle it can affect the contact patches of the tire to the bed of the tubular. Zipp has a deeper channel than our HED wheels or an alloy tubular surface. So,when you're setting up the gluing, check all the variables.<br />
<br />
3) There are minimum tire pressures to run on a tubular for courses with high speed off camber corners. The volume of the tire can help in keeping it on the rim along with the adhesion methods. We've experienced some trouble with Grifos losing pressure through the valve core base and having a 5psi change in pressure by the end of the race. It has changed the way we set up the Grifos on Zipp rims- because of the change in deflection of the tire through the race. This is the same problem Myerson experienced with his set up this weekend, too.<br />

well, I think it probably has less to do with feeling of a tubular set up as it does with easier options.<br />
<br />
Let us say hypothetically that there are some really nice clincher tires, which there are.<br />
<br />
Most tires (except for the challenge options...figures) will seal up and give you the added benefits of a no pinch flat set up...like a tubular. No they might not have as supple of a sidewall, and that is the major draw back. You can swap out tires easily, run tubes if you wish to, and while stans…

No they might not have as supple of a sidewall, and that is the major draw back. You can swap out tires easily, run tubes if you wish to, and while stans stuff can be messy, if you are too close to an ape it takes little practice and intelligence to sort it out. One wheelset with many options. Tubular rims, tires are glued on and that is it. Switching tires on the same wheelset can be a bear...even if you are a badass tire gluer/changer, the work invovled might be a pain. atmo yeah - so my point... if ya a…tag:cowbell.cxmagazine.com,2008-09-29:1198434:Comment:110912008-09-29T16:15:56.429ZGeWillihttps://cowbell.cxmagazine.com/profile/GeWilli

No. If you're going to build a new set of wheels, the Stans option is no more elaborate than tubular. Most people don't have a whole lot of rims "lying around," you pack rat! ;)

Just started racing tubulars this year and can't believe the difference. I confirmed ceramic bearing and upgrade denying, I wasn't really ready to be wowed. Second race on tubbys and I found myself comfortable dropping the pressure and that's when they really lit it up. Didn't take long to get used to them, but we have a weekly cx practice that has allowed me to get the feeling of pushing them a little at a time. Liked the comment about them staying 'upright' which is a pretty good description.…

Liked the comment about them staying 'upright' which is a pretty good description. Much more manageable traction, even when they cut loose. Just make sure they're glued on tight!
