Hi friend, welcome back to BTYCC. Today, we will show you how to fill the mountain bike tire valve and change it. 

Mountain biking is a great sport that allows people to enjoy nature and get out into the fresh air. It is also a fantastic way to stay fit and healthy. However, mountain bikes require tires that are designed specifically for their use. Tires are usually filled with air using a pump. The problem is that there are two types of pumps used for filling tires. One type uses a hand pump, and the other uses a bicycle pump.

If you want to fill your tire with the correct pressure, you should use a bicycle pump. If you use a hand pump, you might end up damaging your tire. In this article, I will explain how to fill a mountain bike tire with a bicycle pump. So let's start!

What Is A Presta Valve?

A Presta valve is the most common valve used on mountain bikes and other bicycles, including road racing bikes. It's also known as an "internal" or "valve-in-the-head." The name comes from the Italian word for the pump head because a Swiss company in Switzerland invented it. A typical Presta valve has three parts: Stem, Body, and Spring.

When you press down on the lever, the stem moves downward, which opens the valve allowing air to flow through the valve. This creates negative pressure inside the tire, causing the air to push against the tire's walls, creating traction. 

The Benefits Of Presta Valves

Easy to install: They're easy to put together, and they don't need any tools. They have no moving parts so that they won't wear out over time. You can easily remove them if needed.

Durable: Because they're made of metal, they last longer than plastic ones. Also, they're more resistant to corrosion. 

Provide better performance than other valves: Compared to Schrader valves, Presta valves provide higher pressures and lower resistance.

Why Is Bike Tire Pressure Important?

Bike tire pressure is important for your safety and the longevity of your bike tires. It's also a good idea to check it regularly, especially if you ride in cold weather or on rough roads. If you don't know how much air should be inside your tires, here's what you need to do:

Check The Pressure On Your Tire.

First, ensure that you've removed all the tubes from the rim. Then look at the sidewall of the tire where the bead sits. There should be some marks indicating the recommended PSI. For example, my rear wheel says 50 psi. That means that when fully inflated, the tire should sit about 1/2″ below the top edge of the rim.

Now, take off the cap of your tire gauge. Then insert it between the sidewall of the tire and the rim. Make sure that the needle points toward the center of the tire.

Finally, turn the dial until the needle touches the number indicated on the scale. Don't worry about getting it exactly right; try not to go past the maximum amount allowed. Once you know the exact reading, please write it down somewhere safe.

Determine The Best Tire Pressure For Your Bike.

Now that you know the current pressure on your tire, you'll need to figure out whether you want to keep it at its current level or increase it. To determine the ideal pressure for your particular situation, follow these steps:

First, find the manufacturer's recommendations for the size of your tire. These numbers are printed directly onto the label located near the valve hole.

Next, measure the distance between the bottom of the tread and the top of the rim. If this measurement is less than 2 inches, then you probably don't need to inflate your tires beyond their factory settings.

However, if the measure is greater than 3 inches, you may benefit from increasing the pressure slightly.

A Step By Step Guide On How To Fill Presta Valve

Step 1. Finding And Removing The Valve Cap

The easiest way to pump up your tires is to use a hand pump. But before you start pumping, you'll need to locate the valve caps. Most modern tires will feature two caps – one on each end of the valve body. Look for either a screw thread or a flat spot on the cap. Remove both caps using pliers.

Step 2: Attaching The Pump

Next, attach the air hose to the valve stem. The most common type of connection uses an O ring seal around the base of the stem. You can also buy special adapters explicitly designed for this purpose. Some pumps even include built-in adapters. Just remember always to tighten the nut counterclockwise!

Step 3: Pumping Up Your Tires

Once everything is connected correctly, place the nozzle into the valve opening and press firmly. This action forces air through the valve stem and into the tire. As long as there isn't any dirt inside the valve, you shouldn't have any problems filling them up. 

Step 4: Taking Out The Pump.

When finished, remove the pump by pulling straight upward. Be careful not to twist the handle while doing so. Also, make sure to replace the caps after inflating your tires. Otherwise, they could leak again later on.

Step 5: Securing The Valve Cap

After inflating your tires, secure the caps back onto the valve stems. It doesn't matter which direction you put them in because they won't come loose during normal riding conditions.

3 Ways To Fill Bicycle Tires With Presta Valve

1) Using Hand Pump

If you're looking for a quick solution, consider buying a cheap hand pump like those sold at sporting goods stores. They usually cost under $10 and work great for small jobs such as inflating inner tubes.

2) Using Air Compressor

Another option would be to invest in a compressor. A good quality unit will run anywhere from $100-$200 depending on features and brand. 

3) Using Manual Inflator

Finally, you might decide to purchase a manual inflation tool instead. While more expensive than other options, some models offer additional benefits over traditional methods. For example, many devices allow users to adjust the air being pushed into the tire without stopping the mid-inflation process.

How To Inflate a Presta Valve With a Schrader Pump?

First of all, we need to remove our old tire by unscrewing its rim tape. Then we'll take off the valve core. After that, we'll insert the new valve core into the valve hole. Now it's time to install the new valve core into our wheel. We do this by pushing down the valve core until it clicks into position. Finally, we'll reassemble the rim tape and reinstall the tire.

Now we need to connect the Schrader valve to the Schrader adapter. To do this, we first push the Schrader valve towards the center of the nipple. Next, we turn the valve clockwise. Once the valve has been turned fully clockwise, pull the valve away from the nipple. If done correctly, the Schrader valve should now be attached securely to the nipple.

Now we inflate the tire. When the tire reaches full pressure, release the Schrader valve and slowly deflate the tire.

What Are The Differences Between A Presta Valve And A Schrader Valve?

Swiss engineer Hans Zwahlen originally developed Presta valves in the 1930s. He was inspired by his experience working on motorcycles, where he noticed that it took longer to change the oil compared to changing the gas tank. He created a new valve to solve this problem that allowed him to quickly drain off old fuel and refill the tank much faster.

Schrader valves were invented by American engineers John F. Schrader and William E. Hettrick Jr. in 1938. Their design used a different method of sealing the fluid within the system. Instead of relying on rubber seals, they relied on metal springs to keep the fluids filled. These designs eventually became popular throughout Europe and North America.

Where Can I Get A Presta Valve Adapter?

You should only need one adapter if you already own a compatible bike pump. However, if you don't have one yet, then you'll want to check online or visit your local bike shop. Most shops carry these adapters for about $5 each.

Can I Use My Pressure Gauge When Installing A Presta Valve?

Yes, but it's recommended that you use a pressure gauge since it allows you to monitor how well the valve works. If there is any leakage, you can exactly see what needs to be done before continuing.

How Do You Fill Presta Valve Without An Adapter?

There isn't a way around using an adapter unless you plan on purchasing a separate pump just for filling up your tires. The best thing to do here is buy a pair of pliers and squeeze the lever until the stem pops free. Then, pull the cap off and place it somewhere safe.

Can A Ball Pump Be Used To Fill A Bike Tire?

No, as mentioned above, most bike pumps require special adapters to work correctly. This includes both Schrader and Presta valves. So, if you're looking to save money, then buying a cheap pump may end up costing you more down the road.


So, which type of valve will fit my bike better? That depends entirely upon your preference. Both types of valves offer their advantages and disadvantages. For example, while Presta valves tend to last longer than Schrader valves, they also cost slightly more.

On the other hand, Schrader valves are easier to find at many stores and typically come with a lifetime warranty. In addition, they are less expensive than Presta valves. Ultimately, it comes down to personal preferences. What matters most is finding out whether or not you like the feel of either style of valve.

Once you've decided, make sure to get yourself some proper tools so that you can install them correctly. And remember, always follow all manufacturer instructions carefully!
