Anyone running tubs + sealant?

Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

Anyone running tubs + sealant?

Hey so I have got my new wheelset, they are tubs however so I cant change a flat that easily although im terrible at that anyway. So a lot of people have told me stuff like "tubs are only for racign when you have a car running behind you with about 3 spare wheels". But iv noticed that you can get this sealant that apparantly repairs your tub for you, you squirt it up into the tyre and it fixes it for you. Anyone done this?

Alternativly are there any bomb proof tubular tyres that never really get punctures like marathon plus in a tubular version?

Im currently running continental tufo tubular tyres not sure how good they are but continental make good puncture resistant clinchers so guess these might be ok.

Links to sealant below.

This one claims that it will give you 3 months of puncture self sealing.

One of my pairs of race wheels use tubulars with sealant. I train with clincher tires and latex tubes with sealant.

Sealant hasn't worked that well for me until the tire deflates a significant amount, but it's gotten me back to where I need to be a couple of times. I have been able to save a tubular on at least two different occasions, though, after getting it home and putting more sealant in it. So in that way it's been quite effective at saving some money and hassle. And you can always carry a little tube of sealant with you if that worried about it. Stans makes some handy little bottles that'll stash in a pocket or seat bag.

Continental is one brand of tires and Tufo is another brand of tires. You'll have to redo sealant ever few months no matter what the brand as it will dry up and cease to be effective.

Changing a tubular is generally a lot easier than changing a clincher in regards to roadside repair. Just pull one off and put the other back on (that should have a layer of glue on it already). Don't take any corners too hot. Some clinchers can be absolutely diabolical to change on some rims involving broken levers and the muttering of many an oath.

There are two kinds of sealant usage: always and just after a puncture. The emergency applicator like Pit Stop is for after a flat to seal, partially reinflate, and get you gong again. The regular sealant is like what is used in tubeless tires. You have to have removable valve cores to inject the tubeless tire sealant. That would be a better bet. But the Pit Stop worked for me once, but then failed me a couple of times. When there was a tear at the base of the valve stem, I don’t suppose anything would have help in those cases. Bottom line, the Pit Stop comes in a really small can that you can tape behind your seat post. Can’t hurt or give it a try. If you aren’t satisfied with it, you can alway inject sealant as a preventative.

I had poor results with Tufo sealant- prone to a stringy valve-clogging mess.

Stan's has been better.

Last month I had a tubular that developed a slow leak and turned into a fast leak. Putting it in water to locate the leak I learned it was coming from the bottom of the tire somehow. Possibly a pinch flat, who knows. There was no puncture on the outside of the tire.

I carry a little 2oz bottle of Stan's sealant in my jersey pocket on rides, used it and squeezed 1oz in the tire and it's been perfectly fine since then. Totally sealed.

I have a set of tubular race wheels that I sealed with Effetto Mariposa sealant. Been very happy with it. Started using it on clincher tubes as well.

Sadly, the prevalence of seasonal goatheads in my area has forced me to resort to the extreme measures of running tire liners, which help but don't completely eliminate flats, and using sealant in my tubes. On one bike that sees a lot of use and that has flat-prone tires, I'm actually running double tire liners with sealant. My incidence of flats have been sharply reduced by these measure but alas, still not completely eliminated.

You can't put liners in tubulars.

I would think more pro tour riders would be riding with sealant in their tubs. I can't imagine being a sprinter in the TdF and flatting on a stage 2 miles from the finish. Sealant should work just as well in tubs as in my tubeless tires and I don't get flats on the road anymore. Anything short of a long tear in the tire should be a non-event.

I read that some pro's use sealant in races like Paris-Roubaix.

Here ya go.

This may be the most debated subject when it comes to conquering the cobbles. Many teams have begun using sealant in recent years. Others contend that liquid latex doesn’t help much on the cobbles, as most punctures are pinch flats. Of the 16 teams I spoke to, seven were using sealant and nine weren’t. That’s actually a surprisingly even split.

None of the teams were eager to talk about what product they were using in the tires. But I did spot Stan’s liquid latex and Vittoria Pit Stop canisters in several trucks.

Thanks so seams like a bottle of stans will deal with any city problems ill face such as small bits of glass or bad tarmac. My tyres are continental giro not tufo. Looks like anything that will **** up an inner tube can be dealt with just by squirting more sealant in?

Yeah, as long as you don't get a huge hole. Just carry a little 2oz bottle of Stan's with you and use half if it to seal one tire.

Yup. Orange Seal in Veloflex roubaixs. Highly recommended. Saved me a podium in one race.

This thread is about tubular tires, not clinchers.

So far Iíve had great success with specialized hell of the north tire in tubular 28mm I believe most Ďpaveí marketed or tire marketed for the cobblestones should be durable enough. And yes the sealant works magic, I use orange sealant itís amazing so far! Repaired a few flats I had with much more delicate (also 110 grams lighter each!!) tires.

I've been using orange seal in 25mm conti sprinters on rough roads, gravel, and commuting.

So far no problem, but I rarely flat the GP 4000 or Michelin clinchers either, so maybe it's too early to tell.

I've had decent results with Bontrager TLR 2 oz as roadside sealant. After using it on a flat I found the tire actually held air better than before. But I did have a flat on another tire it struggled with. I also have some Orange Seal I haven't used, as flats on tubs don't seem that common, at least compared to clincher conti GP 4000Sii I was using before making the switch to tubs.

Do 28mm need a special rim or can I throw them on my wheels the tubs I have are HED Stinger 5.0 50mm aero rim.

I run tubeless tubulars from Clement (now Donnelly) not Tufo. In the last 4 years of running them I’ve had one puncture that required changing and that was when I pushed a worn out tire one ride too far. I use Orange Seal selant in them up until this year when I switched to the new Finish Line sealant that doesn’t dry out. Compared to clinchers where I used to get 6 or so punctures a year, this is heaven.

The additional benefit to this type of construction is that you can use those tubeless repair kits that allow you to plug a puncture without taking the tire off. Dynaplug is one manufacturer this kind of product.

I also have a bike set up with tubeless clinchers. The gap in performance is definitely getting smaller but the clinchers are still heavier and less supple.

YES
caffelatex in vittoria tubulars

works great. year+ between problem punctures. I ride with clincher guys who flat tubes every few weeks...

have used the caffelatex espressor (pit stop equivalent) to save a few rides over the years also

Curious about what happens if you donít use sealant. I would guess that a big source of flats in tubed clinchers is pinch flats. Going to a tubular virtually eliminates these because of the rim design. Iíve always wondered how that would work out with tubed tubulars.
