Puzzling

After yesterday's soaking I went ahead and lubed the chain - it actually had rust on some of the rollers - and the cables where they pass under the bottom bracket. I also wiped down the braking surfaces of the wheels as they were coated with a layer of very fine grit. When I spun the back wheel, it made a strange clunking noise, vibrated and seemed to bind a little at the same time. I thought something must have gotten flushed into one of the bearings. Rather than risk any further damage (and hoping there wasn't anything seriously damaged already) I took the wheel off and took out the bearings to clean and re grease. The bike has 3200 miles on it, so it was past time, anyway. I carefully counted the balls as I removed them - 12 small ones from the left, 9 larger ones from the right. A few of the small ones fell into the hub as I removed them, so I just pushed them through. I couldn't see any reason for the noise I heard, so I cleaned everything, put fresh Teflon grease in the races and put the balls back in. Nine on the
right and, ummm, 11 on the left. No place for number 12. I usually drop and lose a couple of balls when I do this, now I have too many! Try to put it in, and another one pushes out. So, all I can figure is number 12 had been in the hub since the wheels were made and it had finally migrated to a spot where it was interfering with something. The rear wheel's ready for another 3,000 miles, guess I need to do the front now too.
The rain did stop, but the wind picked up, 20 mph with gusts to 30. It seemed like one of those winds that was always a headwind. I actually was using the small chainring going downhill. I got in another 30 miles at 16.4. Tomorrow - vacation day and Christmas shopping. No ride planned.

Is your old bike still rideable for really wet days? It might be worth it to spare the parts on your new one.

I had planned to do that, plus use it on the trainer, but the seat is so uncomfortable, I can't. I didn't realize how bad it was until I got the new bike, and I can't convince myself that buying a new seat for it is worth it.
