Just received these very nice DMR Revolver singlespeed disc hubs. Available in two options, regular 10mm bolt-up and the mega beefy 14mm bolt-up street axle version. (yes... it can accept pegs).

Both models have wide spaced flanges, (building you a stronger wheel), sealed cartridge bearings, both accept a regular bmx style screw-on freewheel and have an IS (international standard) 6-bolt disc mount.
