Second opinions save time, trouble and lives.
When I noticed my bicycle was wobbling, I went back to the downtown bike shop I stopped by a week ago. I needed a screw to fasten a bracket on my rear platform. Bless them, they didn’t charge me anything to do it, so I left a few bucks in the tip jar and hopped back on.
But something was still wrong with my ride. Fortunately, the other bike shop a few blocks away noticed my flat rear tire and the pinch puncture it had sustained sometime after I’d gotten the tires replaced at the first shop a week ago. After charging me $15 to replace it, I left the second shop much relieved and better prepared to pedal my best foot forward.
