Rremovable valve core UST valves are convenient for use with preventive sealant.

I love the dismountable aspect of these Mavic UST valves. And they provide the tool to remove the core (for adding sealant - or getting more volume into the tire from a floor pump to seal tubeless ready tires). Works great but be sure you get the valve to match your wheel. Earlier Mavic Crossmax has rectangular shape and more recent has a rounded shape. Makes all the difference in the world.
