Sturmey Archer IGH 3 speed Reliability

I've been researching the reliability of new Sturmey Archer Hubs. There are a lot of comments about the reliability of the old AW hubs. For the newer hubs many people seem to believe that the quality really went downhill when Sun Race bought them and moved the manufacturing to Taiwan. While some others actually think the quality has improved under Sun Race. I couldn't really find very much on this after about 2007 so I am wondering about the more recent production. I'm particularly interested in the 3 speeds without brakes such as the SR-RF3. Any experience with these?

The current production hubs are very reliable and durable. I have been using a SRF3 for a number of years with no issues. I have also installed a number of them in customer's bikes with similar results.
The new NIG design eliminates the false neutral between 2nd and 3rd as well. This represents a marked improvement in the design.

I have had no problems with the newer 3 speed hubs.

I did have to get a warranty replacement for a 5 speed hub I bought--and I later sold the bike it was on, and when I ran into the new owner a year or so later, he told me he had to get it replaced again. So maybe there are issues with the 5 speeds, or maybe we were just super unlucky.

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

At some point comparisons are meaningless. Both the current and vintage stuff is built to last and proves it every day.

...the story I heard......and it is just that, a story. Might be accurate, and it might not...is that when Sunrace bought the SA brand and machinery, they moved it all to China and discovered that a lot of it was pretty worn/out of spec/poorly maintained. So it took them a few years to get on top of all that, meanwhile coming out with their own improved designs and replacing the worn out production lines.

Certainly that's in keeping with my experience of some of the later SA hubs (but still pre-China)I've encountered over the years

but putting it as a final drive with a Pinion transmission, on the crank end is a bit abnormal a force load.
Or did that idea eclipse ?

that being said I have used a Swiss mountain drive crank a 2.5 reduction gear , to give the BSR a 2nd run through, for 3 more low gears.., in my Brompton..

'/,
As suggested in that discussion I did a post to bentrideronline which you can see here. I got some very good feedback including a very detailed analysis of the torque at the hub with the pinion setup. In that post I also reference the Schlumph Mountain Drive website where Florian Schlumph does an analysis of why he thinks the mountain drive doesn't trash internal gear hubs. The empirical data, anecdotal as it is, seems to support him. The reason for this new post was that one of the comments in the bentrideronline thread was that Sturmey Archer had really gone downhill quality wise and I should avoid them, hence this post. At this point it looks like I will go with the Sturmey Archer hub. I'm waiting on Sturmey Archer to get back to me with the maximum allowable torque on their hub. If it is near 100 NM then I'll go with them, otherwise I can use a Dual drive hub which SRAM claims can tolerate 100 NM and just build it up with a one gear cassette which I can cobble together easy enough.

Thanks for the reply. I checked out your video on the NGI and it was very informative.
