Assembly in my Easton gravel wheels was a breeze. I paired these with 2 oz. of Orange Seal sealant per wheel and am really happy with the results. No issues whatsoever and would definitely buy again.
Installed these stems on a tubeless setup on a friend's mountain bike. Works the same as all other tubeless valve stems. The setup comes with a small tool that can be used to remove the valve stem core, or to remove the entire valve stem in case of a flat that requires a tube. Smart to include that, as I suspect many people running tubeless may not have pliers or a tool that will allow them to remove the valve stem nut.
There isn't a lot to say about these valves, except that they are easy to install, and don't leak. The included rubber grommets are helpful. These are my preferred tubeless stems. I spend a lot of money on tubeless rims, tires, and even sealant, so it makes no sense getting low-grade stems.
