Is there a special 3/32" chain ring for single speed/fixed gear bikes? Am I able to use what's called an "Outer" chain ring in a single speed application?  Something like this

Thank you.
There are 3/32 chainrings made specifically for single speed use, but chainrings intended for double cranks will work just fine if they fit your crank properly and are on the correct chainline of course.
