below freezing for the next few months here and I plan to run toobless in February aafter my vacation, so it would be good to hear how it handles low temps.
Tubeless sealant at low temps
Does anyone know what happens to tubeless sealant at low temps , does it work better or worse ?
Short of throwing a sample in my freezer and seeing what happens to it !
any chemical specialists about who can predict what it would do in sub zero temps ?
anyone changed tires after a freezing cold ride ? or do the cold hardy riders use tubes still ?

RRP puncture guard XC sealant here in the uk has on the side of the bottle works down to -4.
Anyone got any advance on that ? ok we are in scotland doesnt get that cold but im working on a worst case scenario for the strathpuffer 24 of -10.
Might just run tubes - dunno if its worth trying to ghetto continental ice spikes

The static...
freezing point of Stans is 32 degrees F. This changes with movement just like water. Water that is moving freezes at a colder temp than static water. That and it doesn't happen instantly of course it takes time. I've ridden with Stans sealant for an hour or so in temps down to about 20 degrees with no problem. The bike of course was stored indoors in a heated environment, then taken out for the ride and then brought back in. Transit time to the trail head was about 30 minutes. You should have no problems with it as long as the bike isn't on a rack in the cold cruising down the highway for an hour or two to get to the trails. Or you're not out for a whole day riding.
I can't speak for any other sealants. Thicker more viscous sealants will likely stiffen up much sooner than a thinner more watery sealant. My personal preference is to run tubes for winter riding just to be on the safe side. Frozen of slushy sealant won't do it's job as intended. And usually freezing will ruin the properties of the sealant, it will usually cause seperation of the liquid components.
Your call on that one. I've never been out long enough when it's really cold to freeze the sealant in my tires. But then when I haul out the studs they've got tubes in them anyway.
Personally I'd go with tubes for winter riding unless you can find a sealant with a freezing point well below the temps you intend to ride in. Better safe than sorry.
Good Dirt

Learn to change a tire with your mitts or gloves on (seriously).Trail_rat said:Does anyone know what happens to tubeless sealant at low temps , does it work better or worse ?

Well I have used it with sucess down to -35 C with non UST tires that would not hold air without Stans, so it must work somehow or another.....It sure don't freeze at 0 C.
Use mine down to 9 f. sucessfully so far .
I had no issues riding in snow, sleet, ice.
If the tire is alredy sealed, Stans will work in the cold - it just won't seal new holes. I do have some tires that get pin hole leaks in the sidewall due to low tire pressures and non-pliable cold sealant that normally keeps the holes closed.
