What is a Presta Valve Core?

The Presta valve is a type of valve found in most mountain and road bicycle’s inner tubes. It features an inner valve body and an outer valve stem. There is also a lock nut that helps secure the stem at the bike wheel rim and a valve cap that complete the entire system.

The outer valve stem of a Presta valve comes in various lengths, great for different uses. It also has a narrower diameter of about 6 mm, a feature that distinguishes it from Schrader valves that measure 8 mm in diameter.

The good news is that you can use a Presta valve in the smaller hole in even extremely narrow wheels. Presta valve core will fit into this tiny hole and still maintain sufficient strength in the wheel of your mountain or road bike. In comparison, the inner valve body will be held tightly by the air pressure in an inflated tire.

The small screw and nut on the top of the valve body allow the Presta valve to be screwed tightly and remain in place. At all times, you should unscrew the nut to allow airflow in either direction. However, the screw must remain on the valve body when the tire is inflated, and the pump is removed.

The cap protects the Presta valve core and keeps it free from dirt and possible damage. Surprisingly, you can enlarge the holes in the rim designed for Presta valves to fit the wider Schrader valves.

It’s also easy and efficient to fit a Presta valve in a large Schrader rim hole. However, you will have to use reducers to fix the extra space in the tire. Unfortunately, not all Presta valves have removable cores, and you will need the right tools to remove this valve.
