Review on 🚴 Bike Tubeless Presta Valve Stem Kit - Super Light Alloy - Tubeless Valve Stem with Valve Core Remover Tool & Alloy Presta Valve Stem Caps - Available in Various Sizes (Black, 44mm) by Paul Randall

I understand there is some risk in buying a $15 valve stem kit. However, apart from looking cool, there isn't much else to say about them. Immediately after installing tubeless tires, both valve stems broke at the screw-in point of the valve. I've never had the opportunity to ride a bike. I noticed the first broken stem (photo 1) in my garage which was replaced with a pipe in the back. Preparing for the ride, I noticed another broken stem near the start of the trail (Photo 2). Luckily I had a whistle. Really wanted to like them but buy with caution when you look at them.
