I keep getting this recurring problem where my chain keeps dropping onto the BB when shifting from the middle to the lower chainring. It only happens occasionaly (always on the toughest climbs though!).
Adjusting the mech any further to the right causes me problems shifting to the ring in the first place.
Any ideas ??
B.T.W. I've set the height of the derailleur as well as its angle (parellel to the chainrings right?)
