Muc-Off Tubeless Valve 3

Yep, you're seeing that right, this new tubeless valve from Muc-Off has a little shut-off valve on it. There is no valve core in the traditional sense. Attach the pump head, then open the valve and start pumping. Then close the valve and remove the pump head. The advantages are aid to be increased airflow and less chance of clogging, and the ability to easily add sealant through the valve stem.
