Sealant in tubs when fitting .

Does anyone put Stans sealant in their tubs when fitting to seal punctures as they happen so to speak , or do you just use Pitstop after a puncture. My thinking is if I use Stans when fitting there would be no point with the Pitstop , if the Stans sealant didn't repair the puncture the Pitstop probably wouldn't either.

    Depending on the tub, using a sealant precludes any kind of repair to the inner and sealant will not stop all punctures and will not hold high pressure in my experience. It all comes down to how many compromises you are prepareed to make, depending on the type of riding you do.

    I would use it, but I use the tubulars so sparingly that it's not worth the risk of it gunking the inner latex tube. However, if you use them daily, then go for it. The tyre will wear out before the latex dries out.

    Repairing a tubular tyre costs you roughly 20 quid, unless you want to do it yourself, but most folks won't. If the tyre is half its life, it's not worth it... if it's near new, then possibly the puncture is a big one and again might not be worth fixing it.

    I still believe fixing them is a good idea and has its place, at least on an environmental point of view, but moneywise it is rarely a good investment... it might be if you use very expensive ones.. but you can buy Vittoria Corsa for 35 quid or so these days

    Im sure it won't sort all punctures but every time Ive been riding with someone who has punctured the latex has sealed it. Ive only had brief dabbles with riding tubeless (never felt relaxed with the thought of getting stranded with a puncture or having to faff with changing a tyre or even carry a spare one). However one time I was racing I did get a puncture on one which had no latex. I popped some latex in and it did seal...my race was over mind you!

    Yes. I put it in every new tub....last thing I want in a race is a puncture!

    I do, and it's worked for me more than once, including sealing some pretty substantial cuts. So far I've found it to hold high pressure (160psi) perfectly well. I'm using Caffe Lattex.

    Never tried it in tubs....yet.

    If filled with liquid sealant, does the high pressure of a road tub not blow the sealant out thru the valve and gunk the valve up?

    I use Caffe Latex but after an puncture. Does it stay liquid until it's needed if you put it in a latex innertube?

    I don't have a wealth of evidence here. It's caught one puncture for me out on the road that I know about, and I've used it as you describe a couple of times to fix a tub with a persistent puncture; that's then held ever since. I've had very poor experiences with Pitstop, to the point that I've stopped carrying it. I do always carry a spare tub.
