I think most BMX cranks use one drive hole. There are some BMX cranks, however, in 110 BCD. These seem to be the best candidates since they are designed for single speed. Big Cheese and AC Racing make cheap aluminum chainrings in 44 or 46 teeth. Rocket makes aluminum chainrings in 110 BCD in this range. Don't know how good any of these are. The Big Cheese 46 tooth ring is doesn't have any weight reducing holes or cut-outs. That might make it stiffer than the AC Racing.
FSA makes some really thick aluminum 110 BCD rings in these sizes. They are kind of expensive, though.
Salsa makes a 110 BCD chainring in these sizes without pins and ramps. I think it is intended for derailure use, however. It's 7000 series aluminum, so it might be harder than the other brands I have mentioned.
Haven't seen any titanium chainrings in 110 BCD.
I'll use the 46t Suntour that I have for a while. After I decide for sure what chainring size I want, I'll probably buy a Big Cheese or FSA. Still going to troll the bike shops for steel chainrings in this size. Not too optimistic about it.
