Presta valve is also known as a french valve. This type of valve is commonly found on the inner tubes of high-pressure road bikes and some mountain bikes. It consists of an outer valve stem and an inner valve body. Lock nuts and valve caps to secure the stem to the rim may also be provided. It consists of an outer valve stem and an inner valve body. Lock nuts and a valve cap are provided to secure the stem to the rim.
This is a thin, little diameter valve. Presta valves can only be inflated with a specially designed pump. Includes a threaded metal body. A specially designed nut is used on the threaded body to secure the valve to the tire rim. If you want to inflate the tire tube, you must first loosen the valve nut on the top. When opening the nut, do not loosen the entire core. In such cases, the tires will suddenly lose air.
When using the Presta valve pump, follow the manufacturer’s instructions for efficient operation and long life. If your bicycle tires are unstable and you use a pump to inflate the tires, you are more likely to damage the valve. The cyclist can pump air from the gas station’s air pump by connecting the Schroeder adapter to the Presta valve.
There are many types of Presta valves, depending on the length of the valve. Therefore, when purchasing an inner tube with a Presta valve, you need to pay attention to the depth of the rim. If your bike has a deep rim, you will need a long tube with a Presta valve.

Benefits of Presta Valve
- The Presta valve has a little diameter.
- It holds the air better.
- To install this valve, you need to make a small hole in the tire rim.
- It allows for high air pressure.
- It is highly reliable and adaptable.
- Over time, the Schrader valve will begin to leak air.
- The rim with the Presta valve has a small diameter.
- These valves have screws that allow the rider to close the valves at the desired pressure.
- They are available in a variety of lengths.
- These valves are lightweight.
Some Drawbacks of Presta Valve
- These types of valves are longer than the Schrader valves.
- These valves want a particularly designed pump or adaptor to inflate the tire.
- They are not much popular nowadays.
- These incorporate extra components than the Schrader valves.
- These valves have extra steps to unscrew the valve to inflate the tire tube.
