I am in the East Bay. The shop that one woman told me had poor service was Pegasas in Danville. I believe they have another branch (maybe in Berkeley?) also. I also have been to California Pedaler in Danville and Danville Bike (next to the high school) . I have been to the one on Main St. in Pleasanton (can't remember the name of it), and the Alamo Bicycles ( behind Rotten Robbie) in Alamo and Livermore Cyclery in Dublin. I found by checking the web that Dublin Cyclery (which is across from the athletic field in Dublin) carries Marin bicycles (in addition to Pegasas) and Pleasant Hill Cyclery and Eden Bicycles in Castro Valley both carry Bianchi bicycles. I have not visited these yet.
Anyone have any experience with any of these places?
