Hesitancy or outright refused shifts. Goes away with slightly warmer weather. Don't know if it's carbon vs alloy, different grease or the benefits of ball bearings.
Or something else.

Correct. The cold weather effect kicks in at ~30s. It tends to happen more on a bike with Chorus (11), and not so much on others with Record (10), SR (11), and even Centaur (10) - go figure....
But, even in cold weather, it really only does it when I get sloppy.
