32 degrees.. layered just right! I was commenting the other day that my bike was initiated yet since I haven't had a flat. In impressive fashion I got a flat front and back.. neither one went flat right away. The back tire went pst..pst.. pst ever revolution. Whatever I hit was stationary. Of course didn't get the front patch right and was down 20lbs this morning. Got the wise idea to swap in my old rim and tire.. bingo! Good for a couple days.
