Getting tires made was really the limiting factor. All the other fabrication stuff is just bending and mitering. The wheel machine can bend the rim extrusion to whatever size. But a tire mold is a big expensive tool requiring big corporate support to make and use in a big factory

27.5 got a reprieve this year thanks to some major companies making "mullet" bikes. But this time more than ever it seems like churn for churn's sake, especially since this time it's back to a pre-existing tire design. They did not come up with new width, tread, carcass, etc. It will be tough to see how this succeeds in the market since the whole market is in a nose dive right now
