I went for a shorter than hoped for ride on Saturday afternoon.
About half an hour out, I happened to look down at my rear wheel and noticed a pretty nasty wobble. I pulled off the bike path and dismounted to check for any broken spokes. They were all reasonably fine. I noticed a few looser than the others, but nothing major. I spun the wheel and it didn't see as bad as when I was on the bike.
I got back on and continued to pedal and it seemed worse again. I have no idea how long it's been like that. I'm pretty sure it wasn't like that after I repaired my last flat, because I do recall looking down at the tires after that to make sure they were fine.
I ended up riding for about 38kms instead of the ~60kms I had hoped to ride.
I removed the rear wheel tonight and put it in the truck to bring with me to work tomorrow. There's a bike shop next door, Cycle Power, that I'll take it to to get fixed. Hopefully they can get it done tomorrow so I can get back to riding on Tuesday (weather permitting)
Friday's weigh-in put me at 229.4 lbs. That's progressing fairly well, but the weekends of temptation seem to put a dent in my progress. :) At my current rate, I should be at my 200 lb goal by August. Fingers crossed.
