Does this happen on anywhere and everywhere on the cassette or only in a certain range of cogs?
Chain bounces from one row to the next on the cassette. Sometimes back and forth. Seems that it's more common on the middle rows. But I think it occurred on the highest row yesterday, so not sure if there's a pattern. I don't get in the smallest (ie, cross chaining) except when in the larger chain ring, when no problems occur.
The shifter is working, as far as I remember. So it will go into a new gear. Just won't always stay there.
