Review on 🔧 40mm Presta Tubeless Valve Stem - Pair for Enhanced SEO by Sourn Debremarkos

I think these 40mm presta valves are perfect for my mountain bike. I tried other 46mm valves and they were too long. I like that these valves are made of brass rather than aluminum due to the added strength of the threads. I use a rubber grommet instead of an o-ring because I feel it provides a more complete seal when compressed. I really like the shape of the lock nut on these valves because it holds the sleeve in place well. I also like the silver color of these valves instead of the brass ones because they match my bike components better. I don't use the supplied plastic valve core puller because I have valve caps with a built-in valve core puller.
