I think your statement about chain drop is inaccurate. I've only had the
chain drop once, and that was with an Ultegra front derailleur which was a
braze on (can you say flexy as hell!!).

I have a 105 bike, and this has NEVER happened, on my two Dura Ace bikes its
NEVER happened.

I suggest that the LBS is either a) too lazy to properly set up the bike or
b) the chain is worn or dirty and that is a maintenace issue.

yuri- Lately, when I change from large chain ring to small one the chain
simply
drops off (every 3rd-4th change).
Once it even did so when going from small to large chain ring. BRBR
The only advice they could offer me was to change a
few rear cogs up/down so that the chain is more or less "straight" when I
am
about to change BRBR


Third Eye or Jumpstop chain watcher. A plastic doo-dad that will prevent
your
chain from falling off the small ring. Not uncommon with any lever mounted
shifting systems.
