How do i inflate a presta valve

The standard type of valve on most modern bike tires is called a "Presta valve" sometimes called a 'French Valve'. Unlike Schrader valves, which are common on some mountain bikes and all car tires, these types of valves are built to handle high-pressure tires, since the narrower valve stem increases the strength of the tube. Presta valves can be a little tricky to figure out when you are first working to fill one of them with air, how do i inflate a presta valve.

The two most common valve types these days are Presta valves and Schrader valves. They use an internal spring to allow inflation while keeping the valve closed. You can inflate this style easily with any regular air pump. Presta valves are a lot narrower and are commonly found on higher end bikes with narrow rims. They are a little trickier to inflate as they use a manual locknut to open the valve for inflation. These can be purchased for about a dollar at your local bike shop. Notice that you can now let air out by depressing the locknut. The adapter effectively converts your Presta valve to a Schrader valve so that you can use a traditional air pump to inflate it. Attach your air pump and inflate the tire to the recommended pressure. Once the tire is fully inflated, remove the air pump, remove the adapter, and finger tighten the locknut. Then replace the cap. There is another locknut at the bottom of the valve stem.

All you need is a road bike pump adapter, especially for tubeless road bike tires that have a Presta valve in them.
