My 32 spoke 26 inch Raven rear rim is wearing and I will need to replace it soon. SJS are local and will do the work and are suggesting an Andra 30 rim. I am just wondering what else is available? The all up weight of the bike is 110kg max with me, touring gear, food and water so not too much load and I use tyres between 1.75” and 2.0” run at fairly low pressures……..so a rim of around 22mm width seems about right.
I am sure an Andra 30 rim would do the job fine but they seem a bit heavy at 750g.
With the wheel rebuild I was also going to fit the rohloff hub rings, but at 110kg max I do not know if they are really required? I would really like to keep the wheel weight down.
Thanks

Long time since I've had 26" wheels, but the Halo White Line Classic is my go to in 700c for rim brake touring and I'm a good bit heavier than you. The 26" size is I think around 500g, available silver, black/silver and black/black, the latter has a black brake track but is still sold as a rim brake rim, not sure how that works.
I broke two flanges in ten years, then none in the fifteen years since, one of my hubs is without rings, the others have had rings from new. I suspect either the hubs or the wheel-building have improved, though it may just be luck. I doubt you'll notice the weight of the rings on the hub, it's not like weight on the rim. They might get you out of trouble one day, or you might never need them. Thorn's ex workshop manager advised not to fit them unless rebuilding the wheel anyway, but to do so if/when I was.

I assume you mean inner width of about 22mm.
When I built up my Sherpa, I anticipated using tires between 40mm and 50mm width. Using this chart, it told me that I wanted a rim with an inner width of 21 to 23 mm. The rims I got are no longer made, so I am not going to suggest them.
I think you should put the flange rings on. They weigh almost nothing, and their cost is minimal compared to the cost of a hub and and the inconvenience if you had a flange problem later. I was really surprised how light the rings were when I added them.
Andra 30 inner width is 19 and the Andra 40 is 25. I looked at this website, checking the box for rim brakes and 20-23 internal width gave a choice of the Zac 421.

That is an eyeleted rim, I do not know if the spoke holes are drilled at the right angle for a Rohloff or not. If Sapim Polyax nipples are used, I do not know if that matters.
Or, look at other brands. Since I do not buy rims in the UK, I don't know what is commonly sold there.
