VALVE C0RE - Presta

A bicycle valve core acts as a one-way check valve, allowing air to be pumped into the tyre while preventing it from escaping. It is the heart of your bike's tyre inflation system.
They can get damaged form use so they are incredibly handy to have in your bike bag or tool kit

The Presta valve core is the standard on most road, gravel and mountain bikes.
They are handy to have when using tubeless tyres because they allow you to easily swap them out or remove them and inject liquid tyre sealant directly into the tyres. To inflate or deflate, you must unscrew the small knurled nut at the very top and press it down
