I changed my chain, front sprocket and rear cassette today and now I can shift into 10th gear without the chain falling off.
Update #1: I spoke too soon: See this post from the next ride.
Update #2: Problem fixed finally with Miranda E-Chainguard Nut. See this post.
The front sprocket was an easy swap. I'm glad I got a new O-ring because the old one was pinched and broken when I removed it. I over tightened the lock ring because it has a reverse thread and it turns out my torque wrench doesn't click when used in the reverse direction.
The rear cassette was also an easy exchange. It's hard to tell how worn down the old one was because it's so dirty and because the teeth are different sizes and shapes even when new.
Finally, changing the chain wasn't too difficult eitther. The difference in the old (top) and new (bottom) chain was quite dramatic. I lined up the other end of the chain and stretched them both out as far as they would go. The red and blue links are 111 links from the end and you can see the old chain was stretched about a half link. I put on a Connex chain made for e-bikes so hopefully it will last longer than my previous one (about 1300 miles).
