Okay I just changed both tires. It took more than an hour. As mentioned they were both looking worn so I had already bought new ones and was planning to put the new ones on after this weekend's ride. Luckily the big club ride planned for tomorrow was cancelled tonight. I didn't get home from work/running errands until 9:30 tonight and now it's almost 12:30. If I'd had to do other ride prep tonight (starting with digging out my Amfib tights for tomorrow's cold weather) and then wake up early just to get official notice that the ride was cancelled, I would have been cranky to say the least.
I also changed both inner tubes just to be safe. One of the new ones has a ridiculously short stem which I'm sure will drive me crazy so I might end up changing it again. Also I had a really hard time getting the rear wheel on and off the bike. But now it's all back together with new inflated tires. They're Continental Grand Prix 4000s II. I've used Conti Gatorskins before but this is my first set of GPs. I hope I like them! I folded up the unpunctured tube and am keeping it to use as a spare.
As for the cause of the flat, I had to inflate the bad tube and put it in water to find the tiny hole. Then I found the tiny piece of glass in the tire. There was a small hole on the outside of the tire which I had found on the road under the streetlight. But the glass was pushed in enough that I didn't feel anything sharp at the time. There's an old, larger cut in the tire that never led to a punctured tube, so my guess is that the tire is now just too worn and thin to be as puncture resistant as it was before. Btw they're Mavic Yksion Comp tires. I'd use them again.
So. It won't be spring-like on Sunday but it should be sunny and not too cold -- well, we'll have a hard freeze overnight but it should get above 50 later in the day. It will definitely be the better day for being outdoors this weekend. I don't know yet where and when I'll be riding my bike, but I'll be out there somewhere.
