    as i understand it, it is common with certain types of drivetrains, like triples perhaps? it is relatively easy to find both 110 bcd and 130 bcd chainrings, though 1/8" might be more difficult to come by in 110...

    Yes. Simple (and not dumb) question, simple answer. It is the standard for "compact doubles" and was for all five-bolt MTB chainwheel sets up until just a few years ago. There are tons of 110 or 110/74 cransksets out there, so chainring availability should be just fine for the foreseeable future.

    Are you sure that's not a 104? There's no mention of it at all here, and Sheldon is usually pretty danged comprehensive...

    isn't 110 standard for 3 piece BMX? in that case wouldn't 1/8 be pretty common?

    i use 110 3/32 right now and have never had a problem finding chainrings.

    It is, but very few 3-piece BMX cranks even use a spider anymore, let alone have a standard BCD. Thus, there aren't a lot of BMX chainrings that are 110. Luckily, Rocket Rings are super-cheap and always there.
