Sorry, I don't have any advice for a shop in your area. I'm a fan of Edge Cycle Sports & Cycle Care but they are both in the Lake Forest/Laguna Hills area.
The reason I'm posting is to applaud you for your 2nd post in the thread. I read carpenter's post and immediately thought, "OK, but that's not what the OP asked."
