Why BWR use standard SA (rubbish) NIG parts

[SA_SA_SA_SA]

 Given that Brompton acquired an SA hub designer when SA UK folded, it seems a pity the BWR has the same rubbish NIG* mechanism as the standard modern 3 speeds: 

it seems sun race themselves are experimenting with dropping the actuator plate  on some 3 speeds. EDIT it is replaced by ramps that cause the toggle chain to 'oscillate' if between top and low:  http://forum.cyclinguk.org/viewtopic.php?t=100387#p938637

*No neutral between middle and top gears.

Is it just a tooling issue? I know Brompton sell a fair number of the hubs, but tooling up for a fully custom design presumably gets expensive.

I hate that bit of plate.  It rattles and makes complete disassembly impossible without bending it.  Did the original 1980s run of non-slip AW hubs for Columbia Bicycles have the same design?  I've never seen the internals of one.

Not sure, the 5Star NIG looked like it had one**. Brucey might know....

According to AtoB mag, Sunrace saw the 2 AW models and decided  to bring back the NIG only (I suppose they thought it more modern or lawyer proof): perhaps regretting that now?


Anyway heres their new actuator free one explained by the Brucey:

EDIT if you read further down someone seems to be managing without the plate in a modern sunrace NIG 3speed (but needs a later? ramped NIG bit)

Is this the thing that SA call a "drag spring" on the S-RC3?

I don't think I or the linked thread mentioned that model?
That (part 21) seems to be something else in that coaster hub (which shows the actuator plate as part 24 of your above linked pdf)?

The new bits Brucey mentions in a RK3 seems to be driver clutch parts 13 &25 in http://www.sturmey-archer.com/files/catalog/files/299/PART%20LIST%20-%20CS-RF3%20CS-RK3.pdf:---
this has no actuator plate that I can see .

24 is actually a complete driver assembly; the plate isn't a separate part, which probably explains why it always gets ruined if you try to dismantle the hub completely.  It's best to just clean, flush and dry the driver assembly as is.

I think the drag spring on the S-RC3 has the same lockout function for another set of pawls.  I didn't look that closely the last time I had mine apart.  The LH side of a S-RC3 is quite different to an S-RF3 although the RH side is much the same.  One annoyance is that no indicator spindle really fits correctly; I have the super-long axle for 135mm rear spacing imported at great inconvenience from the USA (it's not sold here) and it's supposed to take the Mark 5 indicator according to the specs.  Well, that's much too long and a Mark 4 isn't right either; now I put a normal HSA125 in there and adjust it by feel.

I think the drag spring on the S-RC3...

But the hubs Brucey referred to as having no actuator are the CS-RK3 and CS-RF3 (disk brake ,no-brake hubs), I am missing why the S-RC3 applies to this thread:

NB the paper manuals for actuator plate containing NIG hubs I have seen, all said replace driver as unit. But I think Brucey has replaced the plate: perhaps he will turn up on this thread....
