Some track bikes and some BMX bikes ship with 1/8, but I'm willing to bet your bike is 3/32. Like you said, it is very standard. Even if you did have a 1/8 chain, you could still run it on a 3/32 chainring (but can't do it the other way around).

Also, you probably know this but BCD is the distance between two adjacent chainring holes. You'd want to make sure your current cranks have either 130mm or 110mm between each crank arm/hole before considering a rocket chainring.
