Bicycle Pro Shop DC, Alexandria

Since 1958, Bicycle Pro Shop has helped find a matching mount for everyone from little kids just learning to pedal to United States presidents. The staff of experienced technicians—all avid cyclists themselves, including the owner, Serge, who spent 10 years as a competitive cyclist in France—oversees a stock of hybrids and road bikes from brands such as Cannondale, Scott, and Giant. In the service center, mechanics tighten up loose screws with thorough tune-ups and perform meticulous adjustments of minor yet important details such as the angle of the saddle and the crispness of the baseball cards in the spokes.
