That's odd. My Specialized dealer sells EVERYTHING. Specialized, Cervelo, Guru, Gary Fisher, Orbea, Trek, and several others. And they are able to get other bikes in by special order...like Colnago, Watford, and a few others...even though they're not official dealers and don't have any models on display (actually, I think they have one Waterford and one Colnago at the store).

What I think happens is that bike manufacturers try to bully smaller volume shops into selling only their stuff. But they can't bully large volume stores...this store is a pretty large volume store...
