Stans Tyre Sealant - video - the Path of Death

[TGR]

Has anyone tried this -

I am suspicious of the rate of removal of the pointed object and wonder if that has something to do with the sealing process. NOte the road tyres at the end - when he withdraws the nails he does so very quickly.

p.s. a puncture is really not the end of the world - Path of Death, more like 'Track of Inconvenience' - although DEATH sounds better

i think i got the right end . so its a liquid that could stay a liquid inside an inner tube?when you get a puncture it repairs it instantly ?

 

[bugloss]

It's liquid latex with bits in it. I use it in my tubulars but the brand I have is Continental.

It won't seal if you get a piece of flint in it that stays there while you ride. You need to remove the object that causes the puncture for it to seal.

Plus if your tyre is pumped at 140 psi the air pressure will cause the latex to spew out. No latex no sealing.

Sometimes it works, sometimes it doesn't. You still need to take a spare or a repair kit with you or you'll be walking home.

So my conclusion is close to being right with the demonstration.

[bugloss]

Yes.
Notice in all the demonstrations the spike is pulled out.

I saw a mountain biker riding with latex spraying out all over the place a few weeks ago it covered his arse and his bike. Sometimes it works well and I've ridden several hundred kilometres on a tubular with a hole in it, but there comes a point when the sealant cannot hold any more and it's time to fix the tub.

You'll also have trouble getting it off your clothes, but it comes off your bike with a bit of WD40 and a rag.

I use my sperm to stop tubes from going flat.

Ian,

They say a picture tells a thousand words -




Tee hee hee

p.s. bring back schoolboy humour!!

Nah, when i "do" tyres (couple of times a year) i can usually see upwards of half a dozen puncture sites per tyre, most of them still have the cause of the puncture in the middle of the lump of dried latex.

Plus if your tyre is pumped at 140 psi the air pressure will cause the latex to spew out. No latex no sealing.

Unfortunately, yes, sealant and high pressures don't go well together. No idea what anyone would want a tyre at 140psi for though. Except on a wooden track. Which really wouldn't require sealant!

How about a 19mm tub on an aero rim (Wolber etc.) which need at least 150 psi? I seem to remember running mine considerably higher than that in time trials. Also running tubulars on a racing tandem.

Don't half go off with a bang though :shock:

I can't quite imagine how you can see all those puncture sites in a tubular tyre, as you'd need to unstitch the thing the whole way round to see all of the inner ?

Or tubulars that have to put up with the weight of my fat arse on them.

Plus I have the pleasure of riding on roads surfaced by the king of tarmac and I like to rollllllll.
