I've been going to Avenue Cyclery for over 20 years, and they have always been friendly, helpful and reasonably priced. For little things like bike pumps and replacing spokes, to larger bike purchases

Great, friendly service. I've rented bikes here on various trips. Really nice higher-end roads bikes at good prices.

Top notch. There are some pretty horrible bike shops on stanyan Street but this is the one right here. I can't recommend these guys highly enough for sales and repairs.
