Tubeless in Very Cold weather

[The Cumbrian]

When cycling in temperatures consistently below freezing, I assume that tubeless sealant will freeze, rendering it useless. Are tubes best for cold weather cycling?

Cheers, Michael.

Tis fine... not sure bout below minus 10 though but minus 5 is all good

It might go a little thicker but I very much doubt it'd freeze.

I should have also said that the bike would theoretically be stored cold too, and temperatures would routinely be -10°C and quite often a fair bit colder.

I've applied for a job in Finland, and I'm currently making plans for something that might not happen....

My moonlander came with homemade sealant that was a mix of water, liquid latex and antifreeze. It worked really well, which was handy as reinflating 4.8" tyres was a hassle!

I’ve seen Orange seal work down to -25C (ish) in northern Finland.

There used to be a finnish fat bike group on Facebook many years ago, no idea if they are still about but were helpful to me when I’ve been on there in the past

I've ridden in -25 with stans - no issues. It has glycol in as standard. Some people add more if they are doing things like the ITI but for over here there is no need.

For Rovaniemi in 2015 I have vague recollections of riders putting stans, etc in their freezer to see what happened. If nothing else that's pretty easy to do!

My tubes survived that test really well

I've ridden tubeless in down to -28 °C and had no issues whatsoever. Both Stans and Conti Revo sealant.
Yet, I didn't puncture the tyre nor looked inside it when it was freezing.
Also, depending on rim/tyre combination, you can get an airtight seal without sealant.
I ran my fatbike (which mostly gets ridden in freezing temperatures) without sealant for a while.

My question would be more like "can a puncture be sealed in low temperatures?" and this I cannot answer.

LOL

Been there. Done that. Tried thawing by putting the jar in a pot of warm water. I'm sure it would have worked eventually but I didn't have the patience

With stock On One Fatty wheels it wasn't sealant freezing that stopped me going tubeless!

Almost anything that contains toffee or caramel is likely to break your teeth, especially Rolos and Caramel bars. Curlywurly's are improved though, because you can break them into bite sized chunks.
