It's dropping when going from big to little chainring, sometimes it drops outright, sometimes the crankset seems to "lock" due to chain wraparound (if that's the right term) as part of the process.

Any suggestions on whether its a tweak adjustment in the chain tension? I know I set up the limit screws etc. perfectly so I had thought that was a once-in-a-lifetime setup but I am unsure what to do to fix this.

Ideas??
