3, 4. Why should I get any less just because my religion says so? The thing is though, they don't give you an option to do what you want to do with your gears. "We like it this way, we're only going to sell you what we like because to do otherwise is crazy and not worth our time and effort to stock it."
So I can get Trek to build me a Madone with barcons, a Sugino triple, fat tires and an MTB rear end?
Of course not. Because it's crazy to do so and not worth Trek's time and effort to stock it.
