OK, here we go:
Wheelbuilding data:
Spoke hole diameter 67mm
Centreline to RH flange 24mm
Centreline to LH flange 29mm
This is for a 120mm hub; the shell of a 130mm hub may be more or less centred between the locknuts.
There is a small amount of lash in all gears, but it's just the planetary gears from the feel of it; only a couple of degrees so the "flywheel effect" should still work when climbing. The spring pull on the indicator is very high compared to an AM/AW/SRF3.
The bar-end shifter is very nice, although it will be possible to select positions in between gears; a trigger can't do that, which is why they are the traditional choice. However, the cable pull on this is different to a normal 3-speed trigger.
It comes with a nice LH domed axle nut with the SA logo, and everything else you need except the sprocket. I measured the maximum chainline as about 46mm, so it will fit in place of a Goldtec hub with no changes up front. You can have considerably lower chainline down to "track" standard by moving the spacers above, rather than below, the sprocket. It all feels very well made, with quite a lot of alloy bits.
In the end I decided not to take it apart, since there was no need to respace it so I didn't have to disturb the cones. I'll wait until they produce a PDF manual.
You get everything shown in the pictures EXCEPT the sprocket PLUS a cable inner and outer. I think you get a chainstay fulcrum clip as well but, if not, they're very cheap. I went for a traditional top tube fulcrum clip and seat cluster roller, which means most of the cable is run unsleeved and it can't be caught between the chain and chainring when fixing a puncture.

Now I need to get some spokes.
