At Alpine just ask for Traci! I have to agree about Big Shark being friendly. I took a couple of their classes. Anyway, I'll go ahead and shamelessly plug Route66 Bicycles in Rolla. His website hasn't been updated in awhile. I think business is booming and he's pretty busy. One owner and as I learn more and more I realize what a terrific mechanic he is. If I email him he replies within the hour unless he is off on a mtb race somewhere. Pyannyplayer goes there too. He also lets me think I know what I'm talking about even though I just know enough to be dangerous. Personally I think he's worth the drive.
Good luck and let us know what you finally do.
