Actually, why did you think you had 10 in the back? When you shift, is it clicking for 10 or 9 gears? I'm curious only because if you don't match the number from the front to the cassette, it won't fall correctly no matter how you adjust it. It will jump between gears because it can't quite line up. When tightened, it will work for a short time and then be out of whack again almost immediately. We had a bike shop replace Kit's rear cassette and they didn't count the # of gears before the change. Guess what? They had it wrong and couldn't get it set. They put on the correct cassette and no problems after that.
Check your brifters (or whatever set up you have for changing gears) and see how many clicks you get compared to the cassette. Good luck.

I swear to you, my Ultegra components have been completely trouble-free since I got my Madone in May. It sounds like your cables maybe weren't stretched properly before installation or your bike shop just isn't doing a very good job with the adjustments. When you pick it up next time, test it in the parking lot, with the mechanic out there too, and make sure you are 100% satisfied before you leave there. It should shift quickly and definitively, with no hesitations or skips. If it does not shift to your satisfaction, take it right back inside.
