Bike inner tubes come with valves in order to hold air. There are two types of valves: Presta and Schrader. Most bike tires use Presta valves because they’re more common on road bikes.
Schrader valves are more common on mountain bikes because they’re easier to use with lower tire pressures. If you have a Presta valve, you’ll need a pump with a Presta head in order to inflate your tires.
Bike inner tubes come with valves for a number of reasons. First, they help to keep the air in the tube from escaping. Second, they allow you to inflate or deflate the tube as needed.
Third, they provide an easy way to check the air pressure in the tube. Finally, they can be used to repair a punctured tire.

Do Inner Tubes Come With Valves?
Valves are an essential part of any inner tube. Without a valve, air would not be able to enter or exit the tube, making it useless. All inner tubes come with valves, and there is no such thing as a “valveless” inner tube.
The type of valve ( Presta or Schrader ) will vary depending on the type of bike you have and your personal preferences.
Is the Presta Valve Part of the Tube?
The Presta valve is not part of the tube. It is a separate piece that is inserted into the tube. The Presta valve has a small knob that is used to open and close the valve.
When the valve is open, air can flow into the tube. When the valve is closed, air cannot flow into the tube.
How Do I Know What Valve is on My Bike?
Assuming you would like tips on how to determine what valve is on your bike:
If you’re unsure what type of valve your bike has, there are a few ways to figure it out. First, check the tires.
If they have Presta valves, that’s what type of valve your bike has. Second, you can look at the pump. If the pump has a screw-on attachment for the nozzle, then it’s a Presta valve.
Lastly, if none of those options work for you, take the wheel off and look at the stem itself. A Presta valve will have a small metal cap that unscrews, while a Schrader valve will be solid with no cap.
What is a Presta Valve Inner Tube?
A Presta valve inner tube is a type of bicycle tire that uses a Presta valve to hold air. The Presta valve is a small, metal valve that screws into the rim of the wheel and has a small cap that covers the end of the valve. The advantage of the Presta valve over other types of valves is that it is much easier to add air to or remove air from the tire.
The main disadvantage of the Presta valve is that it can be difficult to find replacement parts if something goes wrong with the valve.

Bike Inner Tube Sizes Chart
Bike inner tube sizes chart. When selecting an inner tube for a bicycle tire, it is important to match the tube size to the tire size. Inner tubes typically come in standard sizes, which correspond to the diameter of the tire they are meant to be used with.
There are three main types of bike tires: road, mountain, and BMX. The following table provides a guide for selecting the right inner tube size based on tire diameter.
Tire Diameter (in) Tube Size (ISO 5775) 23-25 622 26-28 630 29-32 635 33-38 640 39-42 645 43-47 650 48-52 655 >52 660
When purchasing an inner tube, pay attention to whether it is labeled as “Presta” or “Schrader” valve type. Most road and mountain bike tires use Presta valves, while Schrader valves are more common on BMX and children’s bikes. Some tubes are available with both valve types; however, it is not possible to convert between the two without also changing the wheel rim.
Conclusion
Bike inner tubes come with valves to help keep the air in and improve your ride. There are two main types of valves: Presta and Schrader. Both have their pros and cons, so it’s important to know which one you need before purchasing an inner tube.
Presta valves are more common on road bikes because they’re lighter and easier to pump up. However, they can be a pain to use if you don’t have the right tools. Schrader valves are found on most mountain bikes and some hybrid bikes.
They’re easier to use than Presta valves, but they’re heavier.
Either way, make sure you get the right valve for your bike!
