650b (30-584) inner tube?

[roof30]

Hey All,
I have a new (to me) Canyon Roadlite 2020 AL SL which came with 650b DT Swiss wheels. As yet I have not found anywhere which sells inner tubes for them. The Ertro number is 30-584 and the standard size is 27.5 x 1.20. Has anyone got any advice on where I can find some as Canyon haven't been any help and it's looking as though I'm going to have to change the wheelset for some 700s, which I don't want to do unless absolutely necessary.
On another forum someone suggested the Schwalbe SV12 but these seem to be too large (35-584). Can anyone let me know if they will work?
Many thanks,
roof30

In my experience inner tubes need to be the correct diameter for the rim (584) but are not fussy about the profile. I'd buy the 35s

+/- 5mm for the width won't make any difference.

Another option - go tubeless?

I've successfully fitted 26" tubes to 700c rims in an emergency. More than a year later that bike is still on that same temporary fix. Contrarily, a 29er MTB tube squashed into a 26" tyre makes a godawful schlupp schlupp schlupp sound when riding and is bumpy as hell. But it gets you home.

Tubes are extremely adaptable.

Indeed. I have ETRTO 507 wheels on my Airnimal Chameleon with 32mm tyres. Tyres and tubes are hard to come by (although not as hard as the original 520s) but I'm using these Conti tubes.

If someone had told me a few months ago that the same tube could fit both a 32-507 and a 47-544 tyre I'd have been very sceptical! When fitted into the tyre there is quite a bit of spare tube that needs folding over but they inflate fine and so far I've had no problems with them.
