Last week, I was all excited about my new chain and cassette. The cassette in particular seemed so much better than my old one because of the shorter reach to the highest (largest) cog, as I went from a 34 to a 30.
I rode several times last week, and all seemed well. This weekend, I went for a fun ride, and about 15 minutes in, as I slowed in preparation for a stop, my wheel suddenly locked up, and I nearly went a$s over teakettle. I knew I had dropped the chain, which I thought was weird enough, but then I looked down and saw this:
So the chain is down between the cassette and the hub, having jumped 'over' the highest cog. I can't get the chain out with 'ordinary' force, and I don't want to make anything worse. My LBS installed the chain and the cassette, so I'm inclined to take it back to them and see what they can/will do.
How likely is it that I'll need a new wheel? Is the cassette toast? How about the chain? Is my loyalty to my LBS misplaced? Was this caused by something they did or should have done (or not done)? I don't ~think~ there was rider error involved, as I was shifting pretty gently, and not pedaling all that hard.
