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.

Alternatively, here’s a screen shot of just the Sport Tour matrix, maybe too blurred..

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

On this forum, photos are supposed to be less than a half meg in memory size.  Too big and it will not let you post them.  I usually use a 16 megapixel camera, I find that if I photo reduce a photo at 20 percent, it easily loads onto the website.

That rack looks a lot like a copy of the early Blackburn racks from years ago.  I think you just have to live with the forward part being spaced out further than the rear.  I would hesitate to try to bend that front arch so that it holds the front sides closer together, as I have no clue if that aluminum alloy is hard enough to be weakened by bending it or not.

I would not space the rear out that far as you have in the photos.  If you used spacers or extra nuts on the bolts to space it out that far, you risk bending the bolts if you have a pair of heavy panniers and hit a big bump.

That said, if your panniers were quite light in weight, then having the rear spaced out that far might not be a problem.

Ah yes it’s black, for some reason it showed as dark purple on my screen. Thorn did also offer a low decal option as well.

In terms of size, if it is the 537L I have one and am 5’9” to give you a ballpark idea.
