Since I have never had to change a tubbie, it's my worst nightmare. I take a full spare. LBS told me Pitstop is miserable if you are dealing with valve extensions (and I'm assuming you are using a deep wheelset). I would love to get this figured out, because it's a matter of time...going to happen eventually.

u mean the pit stop wont work with zipp extenders on 808?

My experiance with Pitstop is I used it twice. The bad news is I had a 50% failure ratio, but the good news it that it had a 50% success ratio.

My tubulars are pre filled with Pit Stop, so far have not had a problem. But for long races I carry a spare & 1 inflator. Short races I hope for the best. As far as changing the tire goes I keep a razor blade under my aerobar pad, cut the tire & peel it off put the other tire (pre Glued) on inflate & go....

I was told it "might" work at the LBS. Everyone one of the bike mechanics winced, so I asked them about it a few minutes later and they all said no way in hell they would use it with a pair of Zipps. I had to leave, so I didn't get to ask all the follow up questions I now have.

Like another person said, I tape a razor blaze to the inside of my Xlab just in case I need it.

well, not sure your mechanic are giving you the right advice.... have they tried before?

The pit stop will work well, even with valve extender if the hole in the tubular isnt too big...depending of the cut.

Erika Csomor flated at Wildflower, jump off the bike and use the pitstop on a hed stinger 60 with valve extender.... she was back on her bike in 50 secondes and claim third place overall pro....

and there is lots of other expemple. a few athelte on Team TBB have use it with succes in races.... it s quick and you dont need to change the tubular...

Also curious about your mechanic comment about...''never on a pair of zipp'' The brand or model of wheel as nothing to do with this... it s just a tubular extender thing....

Small puncture? It probably works. A cut/slash? Probably not.

I carry it.

the tires/wheels i use, even stretched are a b**ch to get on, and i would rather risk just having that than trying to get another tire on there.

i have never, ever slashed a tire and cant really imagine on the races i have coming up where that would even happen...... that would not cause me to prob crash anyway.

Pit Stop, spare, a razor blade or small box cutter.

Try the Pit Stop first.
If it does not work, use the blade to cut a hole across the tubular, stick your thumb in the hole and rip the tubular off.
Put on the spare tubular.

i know how to change one.......

totally agree..

I used on a fellow competitor's ZIPP Front 606 in a race the other day (I was directly inspired from Keat).
worked so well that he was on the road again within a minute and beat me in the closing 200m of the race (damn! haha)

I had a cut/slash in an Ironman last year on Zipp 404 tubular and no spare, but 2 pitstops. The sealant came out the gash, but I held it in place with a gu wrapper until it sealed; I messed up putting the second canister on and it blew up in my hand. The tire still managed to keep 5 to 10 lbs of pressure which was just enough to get me through the last 40-miles of the bike. I think it's a great product as it saved my ironman, but it's not perfect all the time. I do not think changing to a spare tire would have worked for me because there was a section of the race through deep standing water.

OK.....so I used the Vittoria Pitstop with a flat on my 404 at Boise. You do have to push the can very firmly on the valve extender, but, I have to say it worked pretty well. My question is: now what? Is the tire to be trusted until it wears thin or flats again? Will the the Pitstop continue to work as a preventative now? When I do go to change the tire (either now or in the future) do I have a mess waiting to clean up inside the rim or no more so than say using stans on mountain tubless set up?

Can pitstop be used on a disk? I wouldn't think so because of the way it has to be applied. Doesn't seem like it would work to well with a crack pipe.

I just had the tire replaced at the shop. Not sure if it made a mess or not.

I used it on Saturday for the 2nd time. It didn't work. I had a pretty small cut in my tire/tube and it did nothing but ooze out of it. Spare tire for me from now on.

you are talking a clincher? tire/tube???

because yes, it wont work too well in clincher but work great many times on tubular....still not a 100% thing..

clincher

Nonono pitstop! I had a friend who for the first time in his life didn´t bring spare tubulars för IMUK, biked 10K before his tyre went flat, then blew away three vittoria pit stops (another friend threw him an additional). I tried it once too, but the foam went right through the hole. if the puncture is any bigger than tiny, 1-2 mm, pit stop wont work( vittoria claims 3 mm).

yep...this thread is about pitstop on tubular.... very succesfull.

But you cant use it on clincher. That isnt a good idea and you discover yourself, it dosnt work...

Not according to Tom Demerly...

"Vittoria Pit Stop is particularly well suited for triathletes since they can repair and re-inflate a flat in seconds on either tubular (sew-up, glue on) tires or traditional clincher tires. This totally subverts the need to carry a spare of any type, especially with tubulars. There is no more concern over fixing flats."

<notice photos in the review are of clincher tires>

And I believe everything he says.

And not according to the official Vittoria web-site: http://vittoria.com/...=8164&Itemid=197

tom is a great busy men...just not the most knowledgeable guy when it come to technical aspect like those... I m sure his mechanic were aware that pitstop is made for tubies......as recommended by vittoria.

At team TBB, we do use pitstop but also carry a full tubular spare.... pitstop wont work all the time but for the time it does...your back on the road in less than 60 sec....
