I've got a bike set up with the new Shimano Ultegra SL. I've had it in the bike shop twice now trying to get the front derailer to shift properly. 3 out of 5 times when I shift from the big ring to the small ring it drops the chain (when in the lowest gear on my cassette - it doesn't do it otherwise).
Could the inside derailer stop be set wrong or is this user error?
Any suggestions will be appreciated.
