Sunny and high 50s here too ... downright chilly for August and I wore a long-sleeve base layer under my t-shirt. Uneventful commute, lots of runners out today. I was back on the CX/commute bike and wow, the difference between 35c tires and 23C is insane. I felt like I was pedaling through maple syrup at times.

Will get a new tube for the roadie tomorrow, and then swap out the commute tires for the CX tires and commute on the roadie until winter
