Review on 🔧 Enhance your tubeless setup with Stan's NoTubes Tubeless Valve Stem - Pair! by Ryan Fuhrer

I have mounted them on Shimao Ultegra 6800 tubeless wheels Absolutely no problems so far (3 months ride). They were easy to install and made filling the pipes with sealant a lot easier. I have no idea why Shimano put valve stems in these bikes without removable cores. Shimano leaves a lot to be desired in terms of efficient and logical design, but as long as the market firms can fix their shortcomings, anything will work. Excellent valve stems.
