Review on 🔧 Circuit Performance Shorty Black Valve Stems TR412 TR-412 22mm Low Profile (Set of 4): Enhanced Tire Maintenance Solution by Alvin Bonifacio

This is high quality. Casting and valve construction are excellent. You should have some on hand if you have outdoor gear with tubeless tires and you service your tires yourself. These TR 412 bars are just the right short length for most wheels with smaller tubeless tires and are hard to find in local stores.
