Why do people so fear the unfamiliar?[/QUOTE]

The thing I would fear is that non-tapered spindle that you have to use with the cr*ppy original crank, otherwise there's nothing wrong with a fucntioning unthreaded BB that uses 6003 cartridge bearings, I've got something similar (and familiar) on my Fisher Cyclocross bike: works just fine.
