Review on 🔧 40mm Presta Tubeless Valve Stem - Pair for Enhanced SEO by Mark Repp

The valve leaks around the base as several other reviews have said. I spent hours trying to figure out the problem, thought the leak through the spoke nipples was being caused by a tape leak, but concluded it was the valves. Adjusted and added sealant several times but nothing will stop those valves from leaking. Don't waste your money and time buying them!
