Fuel EX 9.8. Mostly sunny, cold - 17 at the start, warmed up to 23 by the ride's end, definitely some wind but I had so many clothes on I didn't notice it... I saw only one other bike rider and one couple out walking. Spotted 8 deer, mostly on the West side trails. First ride on the 45 North 2.6" studded tires, just installed this morning. They're going to take some getting used to but overall a positive riding effect. Great grip on the icey parts, sometimes the bike wants to go straight on curves and occasionally I got no traction but then the tire 'caught'. Also they handled odd on the off camber trail sections. I was not happy with the ride on the East side so jumped off the signletrack at the 1.5 mile mark and headed over to the West side. Trails on the West side were much more traveled and packed. did the lower loop then the upper loop, returned on the Purple trail. Riding on the snow was much harder than normal due to the higher rolling resistance and it was a harder upper body workout. I call it quits at 10 miles/1.5 hours but it was a great ride. Stopped by The Assembly for lunch on the way home.
