Trainer tires and wheels for 650c sized road bike

Does anyone know of any vendor in the world that sells 650c trainer tires or 650c aero wheels? Asking for a friend. We’ve searched around and haven’t found anything.

Zipp do 650s.

I’m… I thought we looked there. I wonder if these came out recently?

Thanks!
