Narrow Wide Chainring 180° flip?

[Vesatoro]

Before multifreewheels and indexing, most front rings were 180 flippable.

If manufacturers were to go back to symmetrical teeth for single up front, they could advertise the fact of double chainring life... and print massive meaningless graphic pseudo-words on both sides!

And sell half less!

You can flip the chainring. They are not unidirectional.
