I have always thought that chain dropping was caused my not have FD properly set but now I am thinking this is not always correct. My FD is adjusted fine and shifts great but I notice I have dropped the chain 2 times in the last few weeks. No problems as I do not shift under load for FD and all I did was not panic and shift the FD and the chain went back on fine no problems and no chain suck.

So I assume this can happen even when adjustments are all correct and what about chain catchers? I am thinking I might just get one for a piece of mind.
