I purchased a bike in September 2008 that has a 105 shifter for a compact crank; the shifter would also be compatible with a triple. My first shifter failed in November 2008. The internal shifting mechanism jammed and broke when attempting to down shift. The LBS replaced it and the replacement is also periodically sticking/jamming when attempting to down shift and I think it is only a matter of time before it fails. It seems I need to be very careful when up-shifting to the big front gear in order not to get the shifter near its upper limit. Is there a way to adjust this to make it less sensitive?

I had no such problem with an older 105 shifter on a triple.

Let the LBS replace it again, It is under warranty.
Keep replacing it at some point the bike shop may offer an upgrade credit towards a better shifter.
That said the 105's is a hearty group, so my thought is that like anything in life you got a lemon or shimano has a bad batch.

Ultegra 6600 FTW.

If it's under warranty and covered, let them deal with it.
