Seven. Cloudy, cold - 28 to 30 degrees most of the ride, mild NE wind. All things considered, a nice ride, only saw one other rider and very few hikers out. Not surprising as the wind chill was in the low 20's. Dressed perfect but no matter what I do the fingers and toes start to get cold around 90 to 105 minutes into the ride. Just a dusting of snow but enough to make me pay attention on turns. It's been cold enough over the last 3 days for the wee bit of snow to actually stick, especially on the gravel portions of the trails. First ride on the Seven in 2 months. Tom was finally able to diagnose my Di2 issues - a loose connection at the battery. All charged up and seemed to function perfectly. I did get a slow flat just as I arrived back into downtown Geneva, hands were so cold I stopped in Mill Race Cyclery and had them swap out the tube for me while I enjoyed a cup of hot coffee. Can't believe I'm still riding outdoors this late in the year.
