Big Bore, No Core!

[AngryScientist]

I had not seen these, but this is an interesting take on tubeless valves from muc-off. Removing the internal check valve core entirely seems to make a lot of sense for tubeless. Sealant always wants to gum up the valve. Looks like they took the valve external. More air flow and the valve out of the rim internals.

Anyone try a pair?

They are not cheap, as far as valves go, that's for sure.
