2 Tubeless French/Presta valves

I was impressed by how quickly these came. Our sons bike tires kept going flat, until I bought these. They sealed right on and didn’t gave any leaks. It’s nice to not have to fill up his tires every time he wants to ride

Came with everything needed to accomplish the task. Very straight forward to use.

These things leak too much. You really have to crank down on the nut with pliers, let it sit a while, and then come back and tighten some more repeatedly to eventually get a seal. Really disappointing.

Never used one before but was simple to use and had all the tools you need.

Cannot get these to seal on my Mavic 424 rims. I would go elsewhere.

Buona fattura e durevole
