Wheel Temp Drop

I thought this might be interesting for cold weather riders. On my morning ride at -28c this morning the temperature on the wheel dropped by 4 degrees Celsius over the 16 minute trip. On the ride home (-18c) the temperature on the wheel stayed stable. Based on this, at around -20 or so it would probably be a good idea to put some sort of cold protection on the wheel for trips longer than about 20 minutes. I first noticed this on the Minus 33 video, where the wheel temp had dropped down to 10 degrees by the end of the trip (same distance, 6k). Wheel is an ACM2, other wheels will experience different results obviously.

Interesting also to look at the voltage readings at the various temperature points: it actually goes up during the day after it warms up.
