Like this?
That one is 3/32" but has shift ramps which make it easier to move the chain off. The single speed versions without ramps (http://www.bikeparts.com/...lts.asp?ID=BPC153439) will hold the chain on better. Even so some sort of guide will help keep things on when on the edge cogs and it gets bumpy, at least the 1x9/10 mtn and cx bikes need it.
I'll save everyone the trouble, since I've already been down this road... Blackspire make an 3/32 130 BCD 50T chainring for single speed, no ramps or pins: http://www.blackspire.com/...t/83/5948/266572/0/0
You could kill someone with one of these, so it's not the weight weenie option--but it's the biggest non-ramped/pinned 130BCD chainring I've found. MDT used to make TT-specific single ring aero chainrings, with slightly longer teeth to prevent chain drops--but I don't think they're around any longer.
