I'm new posting here, but not new lurking and certainly not new to mt biking Marin, got my first Stumpjumper in 82. Anyway, where is there a good shop with decent inventory, mechanics and knowledgable staff? I know Gravy is probably the best, but they don't stock anything. I like to see options before I buy parts. I'm in Novato and work in The City, so SF to Santa Rosa is my home area. Thanks for the help.
