If you have the frame already the only option to go with disc is to try to find one of the apparently rare 130mm disc road hubs. I've never seen any myself but I 've never looked either. Or modify the MTB axles and cone setup to reduce the dimension between the axle nuts to fit. This will alter the brake side distance between the axle nut and the disc seating away from the ISO standard so you'll want to use a brake system that has the ISO to Hayes style adapter such as Hayes brakes, Avid BB series or some of the Shimano brakes. Some machining to the adapter may be required as they are not normally called on to be THAT adjustable.

All in all I have to wonder what the hell the frame designers were smoking when they set it up for a 130 mm spacing.
