The roads were wet from the night rain and the temp was 33 degrees, when I got to work everyone was talking about the black ice on the roads and how the cars were skidding all over, I never felt the ice, I just rode to work as usual and never slipped a wheel. I guess it's time for the studs, I was planning on putting them on Saturday anyway. Last night I replaced my big ring, chain and derailure pulleys. The bike shifted like new again, The forcast for the day is the temp is supposed to drop so the ride home should be on the cool side.
