It's not the chain itself that fails, it's the chain guides (at least that's my understanding), which causes the chain to stretch. Replacing the chain itself won't do anything to prevent the failure. The chain should last several thousand kilometers.

My understanding is that the "preventative" replacement of the affected parts, when factoring in labour, isn't really worth doing.

If I'm wrong in any of this, I'm sure folks who know better than me will chime in

Not even sure if -40 degrees is cold anymore ?
