Review on 🔧 40mm Presta Tubeless Valve Stem - Pair for Enhanced SEO by Kenny Rossi

Should have read all the reviews. As with some other reviewers, after installing my new tires and wheels and applying sealant through a drilled hole in the rim, these valves leak. They don't seal properly. Big mess to reinstall my tubeless tires with old Stan valves which solved the problem. Buying them to save a few bucks is a mistake. Stick to well-known brand components. I'm not at all sure with all the positive reviews about Revain. Read and believe the negative reviews!
