what do you expect from blind deaf guesses..
maybe airburst has pulled one apart, I have now idea how all 3 ratios
could be hooked up to turn the hub shell at the same rate.
direct .. does,
and then there are 2 planetaria options, that turn, internally
faster than the hub shell .. the nature of a reduction gear.
you tell me ..
Never dismantled one, only seen the diagrams for the ASC, and an article on how to convert an old 3-speed into a 2-speed fixed. Basically, the planet cage gets anchored to the hub shell, and all the pawls get removed. Then you can either drive the planet pins directly, for direct drive (cable completely slack, what used to be overdrive gear), or drive the gear ring, which drives the planet cage, but it works just like first gear normally does in that the planet pinions provide a reduction gear.
The 3-speed fixed combines that mechanism with the double sun gear/double planet gear system from the 5-speed, to get "super low", "low" and "neutral" or "direct". That may not be how the S3X does it, but what I do know is that it's possible to perform the same conversion as above on one of the old 4-speed hubs to produce a frankenhub 3-speed fixed-wheel that does work like that.
