Pre Stann'ed tubes

Postby Mulga Bill » Fri Aug 04, 2017 7:50 pm

G'day everyone

Ive got some tubes for my fat bike that I pre filled with Stan's sealant 2 years ago for a trip. They haven't been used at all, would there be any problem with using them now, or should I refill the tubes? The stan's is still liquid inside

Thanks for the advice

Is the sealant still liquid after two years? I always thought it was only good for about six months.

I've got a feeling that was the case back in the good old days when tubeless tyres were as porous as, water vapour could migrate through the tyre... I haven't had any issues with newer tubeless tyres, and I suspect tubes, which are designed to be non porous, are the same.

yes its still liquid inside. I probably should draw some out through the valve and do a bit of a check on it I guess. I suppose I could put some in a dish next to some fresh stans and time any difference between the 2 solidifying.

Of cause it might be easier to just prep a new set of tubes.

I'd do a check. It may still be liquid but I would expect at least partial decomposition over that period of time.

Is it possible to add sealant to tubes with a presta valve?

Perhaps I should have asked if it was easily added?

Yes, if you have tubes with removable cores.

Tubeless valve stems are typically presta and have a removable core. You can get a syringe with a presta connector for filling.

Thanks for the info and link Ron.

Which setup have you opted for with the Fargo?

I'm struggling to make my mind up as to go with one of the tubeless setups or simply to add some goop to my tubes.

I'm not entirely sure I want to deal with the mess.

I want to pull finger though and be ready for a trip as soon as the rains calm down some.

I've gone the full Stan. Stans rims, rim tape, valve stem, and sealant.

Thanks for the prompt response.

I've been scrolling back through a few threads and in your Fargo thread just before spotted:

The tyres were tubeless 2.1 inch Vittoria Mezcals. I was very happy with their performance, they rolled quite well on sealed roads and gripped nicely on the dirt. I can't recall any moments, a single slip or slide from them. They were fairly cushy too, so absorbed the bumps nicely. And they held pressure so well I only got the pump out once to check during the whole tour.


So it sounds like your setup is a success

Anything you'd change looking back?

No, wouldn't change a thing. :)
