Are these the same size.? I've a new rear wheel from a Carrera bike, wide rim 36mm internal. Not sure if it's 650b or 27,1/2. No size marking on it that I could find. Perhaps it's under the wide rim tape. Could even be tubeless but having never come across one I not sure. What's the difference?
It's of no use to me so will put it in the sale section soon.

Yes, it's the same.
Re: 27,1/2 or 650b gravel wheel
Being super picky some might say that something flogged as 650b is a nice French road wheel that has a certain charm and takes nice wide tyres whereas 27.5 is a nasty modern MTB size that is either the new thing or obselete already. Possibly something sold as the later may have a wider internal width or maybe it won't . It won't be for sale in silver though.
Either way, on the whole the only thing you worry about is the width. A little bit and thats all.

Here's a typical tubeless rim:

The distinctive feature is the flat (or even sloping outwards) shoulders to the central depression. This helps the tyre beads move outwards and lock into place.
