Agree; I ruined a tire while riding over the Astoria Bridge many years ago, and was surprised to find a bicycle shop in Astoria that was so completely stocked to handle anyone.
certain amount of winging it , like selling a disc wheel off a bike on the floor, and then replacing it later .
Since Touring route is south , we have a friendship with another shop in Newport ..
people that want Campag 10 speed stuff . not carried.. they
occasionally have to limp down the coast another day or 2 and by then, with advance warning ,
the other shop will get it orderd for installation on their arrival..
Every thing.. in-stock takes access to a millon + bucks and a big warehouse sized place
with fork lift shelves to stock it all .
Those are describing Distributors .. not retailers..
