so the small chainring on my crankset is a 44 tooth. so a 17t cog will probably ideal, yes? and with this set-up i wont have the one lockup location problem from what i've gathered, is this correct?

I realize there are much better hubs/wheelsets out there for fixies, but i'm mainly lookin for a safe, cheap alternative to dumping all my money in the hubs. and a suicide hub definately doesn't seem safe to me, so the cheap NYCBikes wheelset looked to be the best option. Unless anyone has had a bad experience with that wheel/hub, that is.

The IRO wheelset was the other one i was considering, but its $40 more with no cog or lockring for the rear wheel - though i wouldnt mind having these quality wheels. does the sealed bearing make a big difference for a commuter bike?

Thanks
