Cannondale is the latest big dog bike manufacture to put out a prototype cross bike with disc brakes. Rear wheel spacing on the Cannondale is 135mm, but there are 130mm hubs with rotor mounts out there if that’s what you need. Right now this trend is like a runaway team of horses. Where will it go? If your are a Campy user, well MLW has 6 bolt disc hubs for you too. Whatever your flavor MLW can build wheels to your specifactions with the highest quality results.
