I thought of this a couple days ago, just now posting. I bought a new seat earlier this year, and it's carbon. Is this a problem when it's -30F? I'd hate to have it get all brittle and shatter while I'm riding. Anyone used a carbon fiber seat in really sub-zero conditions?

Velo news Tech Reports had something about this last winter, but I can't find it anymore on the site.... Basically, they said that the structural properties of carbon fiber are not affected by cold temps.

If carbon fiber couldn't handle -30F, it wouldn't be used in jet wings or propellers.

Well that pretty much ends that conversation.

Good. Because I just got done putting a carbon bar on my winter bike.
Not that I needed carbon on the bike I ride through snow and slop. It's just that I had the bar laying around and figured I might as well run it and enjoy it.
Heat will cause CF to explode.
Cold will cause CF to shatter into a zillion pieces.
Even my dog knows this, he told me this morning while reading his copy of 'Ride' and posting on the forums.
Don't do it bro'.

Correct. To add a little info on this, I'll comment.
Carbon fiber products being made up of two materials. Carbon, which is always brittle, and only becomes flexible as the radius of the threads are reduced to the point where when you bend it, it doesn't have a radius large enough to create a bending moment to fracture the material. The other is a plastic, that being Epoxy. Epoxy has a glass transition point (point where material turns from flexible to rigid) much higher then room temperature, so in use, its always in its "brittle" phase. Therefore, if its 90* or -30*, the composite is still below the glass transition phase, the properties are going to be about the same.
How does carbon react to rapid temperature changes. Say you are riding in sub 30 degree and then you bring your bike into a warm house. Will this cause any damage?

I don't have a CF seat, but the other CF bits in service (ergo levers, frame, frame parts, forks, etc) don't seem to mind the cold and suffer no ill effects from the 100*f swings from inside to out. No worries, mano.
