I was asked to address concerns on this forum. This is from
http://www.alienbikes.com/gear.html:
"High flange cartrige bearing hubs. These snazzy hubs are available in front or rear, silver or black, 36 hole. The rears are 120mm spaced and include a 1/8" 16T cog and lockring.
The cog is not that great so if you ride aggro (skids, etc) a high quality CNC'd cog is suggested"
I hope this adds some substance to the discussion. Please don't hesitate to contact me with any questions regarding the group buy. There has been an extension as Joseph hopes to break 50 orders (we're close!)
