Thanks for the feedback. Interesting to hear that others have experienced similar problems.
I changed out the cassette early on, and I THINK that I changed from an SRAM to a Shimano, though I'm not certain. I do know, though, that at least one of the cassettes that I tried was SRAM. I'm curious, now, to see if the other bike starts acting up, or if it was just the peculiar mix of parts that I had.... Silver barends, LX rder, Sugino XD crankset, SRAM/Shimano cassette...
