-30C Freehub lube?

My guess is it isn't the oil, it's water that's freezing causing the
problem. It's happened to me in the past. Strangely, leaving it out
works better as the ice is displaced never to return, but if it warms
up, the water pools, and refreezes again. Just my guess.

That's what I'm thinking too and that the water you mentioned is condensation. I'd like to figure out a way to stop the freewheeling from happening as it's annoying and dangerous plus I don't want it to become a permanent thing whilst I'm 20 or 30 kilometers from home and on country/backroads that do not have public transportation.

Is there any way to leave the bike in the cold all the time, rather than
bringing it into the house? I think it would be worth it.

I live in a 2nd floor apartment and leaving the bicycle outside overnight would guarantee that I'd have to walk the next day as the bicycle would be long gone.

Cheers

Too bad you don't have a balcony. On a recent trip, we saw several
residences with bikes stored outdoors on balconies. It looked pretty
secure to me.

I guess one downside might be having the bike get messy with rain or
snow, then having to lug it through the clean part of the apartment.

Question. Does a warm object moved into a cold atmosphere cause
condensation? I always assumed that it was the other way, when
moisture in the air was cooled to dew point temperature, i.e. when a
cold object was moved to a warm atmosphere.

If you take a cold wheel into a warm room it will tend to condense
moisture on its outside surface, assuming it's below the dew point in
the room. A little water on the outside is harmless.

On the other hand, if a warm wheel is taken out into the cold it may
cool below the dew point of the air *inside the hub*, resulting in
condensation inside. There is no immediate way for this moisture to
escape, especially since the inside air is contracting, sucking cold
outside air through the seals.
