MOHEGIA Tubeless Valve Stem 40 mm, Pair Alloy Presta Valve Stem Kit with Valve Core Remover Tool and Valve Stem Caps,Fit Mountain Road Bicycle Tubeless Rims

They have a major design flaw. The rubber grommet at the base is too small and too round. It does not work to stop air leaking. Spend a couple bucks more and get some proper ones. These are a complete ripoff.

These work great! Uses these on a GT aggressor pro stock rims and it has been flawless! Easy install and pretty strong for the price.

Valves are awesome. Air goes in easily and fast. Super slick and easy to pump.

Not bad, but the rubber on the bottom is on the denser/stiffer side, which affected seating. Had to thicken up the sealant with pepper grounds to get it to seal.
