I was thinking I'd like to get a CX bike (dreaming) with disc brakes to use as a commuter and also for some road riding. Because it would be a multi-purpose bike I'd like to get an extra set of wheels.
Looking at a number of forum sponsors I don't see anyone selling 700c wheels with hubs that accept disc brakes, at least not in the 130 mm spacing for the rear hub. I see 29'er wheels but as I understand it, those wheels will not work since they are 135 mm spacing.
So is the only alternative to get some custom wheels built? Obviously there must be some 130 mm rear hubs what accept a disc brake since bikes are being sold that way, but it's hard to find the wheels.
