Nice ride in but, my 2nd flat in as many days of riding. I had a flat on Friday afternoon's ride home which I quickly changed because of the cold. Since I couldn't locate the source of the flat and, yesterday was supposed to be among the coldest days of the year, I bailed, taking the Metro instead. This didn't bother me so much as I still have the remnants of some kind of chest cold and the rest was justified. Well, I got another flat this morning, luckily it was warm and I easily and quickly changed the tire along the waterfront. I was able to do a thorough inspection of the tire at work and found a glass or rock shard lodged in the tread-barely visible. I used my Leatherman to pull it out and it quickly shattered. Luckily I was still able to locate the miniscule hole and patched it with a Slime Skabs tire patch, I also patched the tube and am fairly confident that both should hold. Even though I haven't had much luck with patches, I'm currently running only 75 #'s in my CX tires-that shouldn't put too much strain on the patch. We'll see. Other than that I'm going to enjoy the nice temps (mid 40's today) in anticipation of another snow event tomorrow evening/night. It would be fun to ride in on Thursday with a few inches of fresh snow on the ground. Also, I'm hoping to resume our lunch time ride tomorrow, we cancelled the last one.
