I took it back and complained. Yep, limit screw issue. Now it shifts like a dream and they threw on some new brake pads . They also taught me about the 5 positions on the 105 front derailleur so I can stop the rattle if I crosschain a little.

Plus I walked out with some shorts on sale and some toasty tights. And in love with $230 Specialized sunglasses that I can't afford. Not a bad trip to the ol' LBS. Finally. The good mechanics were there in addition to the guys who did a shoddy job last time. Keeps them on their toes I guess.
