I figured out that the shifter problem was due to the lubricants that were used not liking all the cold. Some penetrating oil and a short blast of WD-40 got it working again, and then some bike oil to keep it working. I plan to get some Teflon lube.
Today’s early morning ride was a bit too long for the conditions. It was about 18 degrees, a windchill of 11 and probably around a zero windchill on the bike. It was definitely colder than the 23 degrees and “feel like” of 24 that my weather app reported. My fingers and toes were frozen when I got home. Also, it was just too cold to do much speed on any downhill sections.
Today’s ride was a 12.4 mile rolling hills route. Pace was very limited by the cold at about 5:10. Weight was 150.8
