I've run into quite the opposite. Though I'm not a bike racer I do appreciate the role bike racing plays in driving biking innovation and popularity with the general public. My experience has been that when I have staff at the LBS who are passionate about bike racing their knowledge usually spills over into all facets of biking. In fact, I'm a little suspicious when I'm at a bike shop and the person I'm talking with could not name a bike racer other than Lance Armstrong and Greg Lemond.

To me bike racing fuels the passion for bicycling like nothing else and if your LBS doesn't know anything outside of racing this does seem odd. Maybe they have the knowledge but are just horrible at serving their customers. Either way, if you cant get the service you need go some place else or learn what you can from sites like this.

Good Luck!
