130mm Rear Disk Hubs
Velocity USA has a hub that they call the 'road disc'. It's a generic hub and only costs $67.25. It is available only in 32 holes. Yeah!
As of spring 2007, the only way to get a 130mm spaced rear hub with disk is through buying a FSA wheelset. It's really too bad that the hub is not available separately.
