Tips from locals
Regional cycling store located just across the park. They sell Specialized, Cannondale, Felt and Orbea. Service department handles everything, usually while you wait. They also have a full line of accessories for both road and mountain bikes.
If you want to bring your bike to ride downtown and need to pick up a part or get a tune up, this is where to go. If you plan to hit some more serious trails on Mt. Tam or Annadel State Park or coastal roads, these guys know the places to go.
