This is a 76, along with a 53T little ring:

I’ve wanted one of those 60t bespoke De Luna’s for a long time. A friend of mine (head mechanic at my LBS) has one on his argon electron c track bike with the same dura ace crank and it’s killer. His girlfriend uses one her track bike as well. Some serious business.

Anyway, the photo came from here.

The 76/53 appears to be a simple overlay.

There are later photos showing the ring mounted to the crankset, as well as mounted to a Brompton, and a couple other frames/cranks.

9t is the thing in BMX, integrated as part of a Hub .. with a massive oversize axle..

The 1&2 speed Free-Hubs Brompton uses have a Shimano pattern 9 spline. their smallest tooth count is 12...

screw on freewheels include the pawls and 2 rows of bearings , so they must have a bigger diameter like 16t ...

....

Not to mention, the 11-tooth cog will wear out much faster than a 16-tooth cog.

Not part of the hub, part of the driver (essentially a free hub body)
