I haven't used them, but I hear the Assos 3-glove system is good. A good description here and good price here.

I like the thin wool lining in Ibex gloves. They seem warmer than pile, especially when wet. I've used both the Ibex Kilometer Gloves and Ibex Climawool Gloves in cold, wet weather -- cross country skiing, snowshoeing, and climbing. I've only used the Kilometer Gloves while cycling and they worked well.

Ibex also has a Backcountry Glove that's warmer, but it looks a bit bulky for cycling.
