I have a DT swiss rim thats a 26mm outside and a 19.5mm inside ETRTO 622 x 19.5 measurement. Can I run this sensibly with a 2.3 tyre on ? or is the rim woefully undersized ? For a 29er 130mm full suss trail bike. The tyres were previously running on Specialized ROVAL rims which measured 26mm Outside and 20.5mm inside (although those were classed as 622 x 21) they came up ony 20.5
it will be fine.
Does it not compromise the handling if the rims to narrow, or am I reading too many mags ??
You're massively over analysing.

I tend to do that 🙂
Heres the background, stumpy FSR 29er with stock ROVAL rims and crappy OEM hi lo hubs. Supposedly 21mm inside (but measure up at 20.5mm) with 2.3 tyres
Garbage freehub fails.
Dont want to carry on with those wheels as they are pure rubbish, Rims seal tubeless very badly indeed and freehub if replaced even under warranty will reportedly fail again as it is utter throw away s***e.
I also have a nice hardtail with decent enough DT wheels on with 19.5mm inside rims.
So I have a choice, do I invest in some wide trail wheels for the trail bike, or use the slightly narrower DT wheels on the Stumpy, and when the marathon season starts again, invest in some nice lighter wheels for the hardtail which I use for marathon events.
Use the DT's for now and see how you get on?

Just swap them back and forth????

Seems so ! Can we agree to use the word "[u]slightly[/u] over analysing"
Which makes me seems less mental 🙂
Mavic recommend the 717 for up to 2.3 tyres, yours are internally wider. People get very excited about the difference, but the difference in profile between an averagey rim like yours and a fat one isn't very big at all. (I'd happily bet that most of the people who believe it's important couldn't tell the difference in a blind challenge)
I thought Mavic recommended 2.1 max on a 717 ?
The website says 2.1 but the wheelrim stickers and manuals say 2.3.
I struggled with 717s when Panaracer Rampages. Even quite well inflated they felt like were going to roll off the rim on off camber stuff.
Changed to an EN521 and its fine now. So try the tyres on the DT rims and see how it goes.
I had rampages too, some time ago, they were a bit rolly if I remember
I ran 2.25" tyres on a 717. They felt fine, they were (probably) a bit grippier than 2.1" tyres. I have tried the same tyres on a Crest, Olympic and Podium rim. They felt very similar.
