15 F & clear. Freewheel froze up on me halfway though the ride. Forgot that it was wet out on the last commute & then temps plummeted. Had to stop and warm it up in my hands & blowing on it. It took a few minutes but it worked. I pretended to ride a fixy for the last couple of miles so that I wouldn't lose pawl engagement again. Hopefully it'll be ok for the ride home. Gotta remember to lube/flush it tonight.
