The most and the worst of ice has melted away, and I've been riding with the 9:Zero:7. But I managed to fall today in a stupid place with slow speed (so no damage). Temperature dropped to near 0°C and some black ice had formed in some places. I think I will finally commute tomorrow with the cyclocross bike and studded tires. The weather forecast looks a little better too:

But as we have seen, the weather has been very unpredictable. Interesting times...
