That's a good summary of the lighter weight versions G. Thanks for that.
I've often wondered how we have decided on how much pressure difference we should opt for front and rear, and it seems you do a little more than most with up to 4psi. I'm not even sure how we would collect data for that. Pressure sensors on each tire? Weighing the bike and rider on two scales with the rider in attack position?
The AL XC seems to be a similar design to the E-bike version, where the shape of the insert structure is predetermined and independent of the tire size or shape, so it's not surprising our results had some parallels.
The two new versions, Enduro and DH, seem to start out as a T structure and then bend into a Y determined by the width of the tire, meaning there should always be sidewall support, as long as there is air pressure to keep the tire round. I'm curious about this design when running flat. It may provide good protection but, depending on tire size, not as much sidewall support?
