Every other expensive carbon frames allows the customer to chose whichever drivetrain setup suites their palate. Pinion gearbox are only available from the manufacturer from what I've been told so it's silly to list a frame and gb price separate.
other frames let you choose your drivetrain. so does this one: buy buying a zerode, you're choosing a swank drivetrain
or, think of it as a special, over priced frameset that doesn't require you to buy a drive train if that helps
whatever. if you're looking at the combined sticker price and thinking "what a ripoff, i would be spec'ing a budget ass drivetrain and saving me some money" i'm not sure why you're even considering one
