Roadies buy what the Pro's race and discs present issues that make them ill-suited for road bikes:
1. Weight penalty and, well, folks spend anywhere from $1 to $5 a gram for weight reductions on road bikes.
2. Wheel change compatibility issues. When a pro gets a flat they slap on a replacement wheel that may or may not come from their own team, i.e., Mavic neutral support. It's been hard enough with variations of Shimano, SRAM and Campagnolo 9, 10 and now 11 speed in the peloton, getting a common fit for disc calipers and rotors would be a nightmare.
3. Too much of a good thing. Road bikes already have more than enough brake power on the front wheel and the rear brake is nearly useless for anything other than scrubbing off speed on long descents. So, adding a disc, even with a small rotor, would be overkill.
