There are a lot of bike shops in the Bay Area.
I view shops on a spectrum of Performance Bike - Mike's Bikes - Summit - Specialty.
Cyclepath sits perfectly between Summit and Specialty. You can drop $10,000 on a bike, but you can also drop $2,000. The maintenance service isn't an arm and a leg and if you don't actually need service, they'll let you know.
The owner, Arkady, is an ex-olympic Russian cycling legend and treats cycling how it should be, with a meticulous attention to form, gear, and workout regimen.
During my last triathlon I had Arkady fit me on my tri-bike, which was over an hour and a half long. Not only did my bike feel 50% better on my next long ride, but Arkady fit out numerous components, from the stem to the angle of my pedals on my shoes, to maximize comfort and watts -- absolutely world class experience.
