Yeah, I spend a lot of dough at Performance in Redwood City. The Team Performance 10% back is awesome.
My LBS in San Bruno is cool but they rarely have the parts I want. I do let have them work on stuff I don't have the tools to work on like installing headset races and cups. They also only sell Specialized, blech.
Valencia Cyclery has a great service dept and carry many hard to find parts.
American Cyclery is pretty good too. Nice bunch of guys. It's just a pain to get to from San Bruno.
The Freewheel on Valencia is good too, and is where I bought my Bianchi Axis. They have a nice selection of Bianchi's, Kona's, and accessories too. One disappointment is when I went to look at a Pista and the guy tried snowing me about how the Pista frame is so much better than a SOMA Rush frame.
