I need a set of inexpensive disc hubs, front and rear. A front hub with a 9mm to 20mm conversion would be preferable, and a hex-nut rear axle in 10 or 12mm would be choice. I have looked at Atomlab GI's, Halo/Diatech Spin Doctors, Shimano Deore's, Woodman Bill's and some others. Anyone have any recommendations? Like I said, cheaper is better.
