Road Wheels and Disc Brakes
Wheelcraft. Australian, they make a 700c wheelset with MTB hubs. Need to see the axle spacing required. Not much written about this. These folks appear to be one of the few doing it.
However one thing to watch out for is the stress. According to Alan Cline over at "Co-Motion":http://co-motion.com, who wrote to saying:
I feel the canti brake setup is the best for touring - disk brakes interfere with rack mounting and make packing the bikes (with couplers) more difficult.
Disk brakes on rigid front forks are an especially bad idea -when the braking forces are moved from the rim down close to the hub, it places incredible rearward stresses on the fork. This is exacerbated by heavier loads. We do not offer a disk brake on our forks.
