At this posting, I'm waiting on a couple of wheels to be rebuilt by Wright Bros. I could have gone to Performance Bicycle in the U District, but there is no equal in Seattle to Wright Bros. (that I'm aware of).
It is the rare occasion to converse with the actual owner (Charles) of an establishment, and that's what you'll find there. That, plus the combined experience of quality work, the overcrowded shop piled with bikes and parts, the hearty smell of grease, and the sense that I'm leaving my trusted bike in good hands that keeps me coming back. On this last visit, before they quoted me a price for rebuilding my wheels, they offered up the class to learn it myself. I'd have done it if I had more time.
I've been a member for five years and have taken their repair classes before - that in itself builds a sense of loyalty and community among the members.
NOTE: Wright Bros. does not do much in the way of sales of complete bikes, mostly just parts and accessories.
