The main reasons for Presta valve superiority are:
- Presta valves hold air better – so they say.
- More tube varieties with Presta valves.
- The narrow design allows for a smaller rim hole.
- The pros use them, so they must be better.

What is the ideal Presta tube valve stem length?
Presta valve inner tubes are available from a range of makers with valve lengths up to 80mm. There’s no harm in using a valve longer than you need, although it might look a bit odd to use a...
Why are Presta valves so difficult?
because the tube valve 'self locks', i.e. only opens under pressure from the pump line, when you stop pumping, it locks. this means the pressure in the pump (which is what is being indicated on the dial) is not the pressure in the tube. sometimes though, it seems to stay open and i get a good (accurate) reading.
Are Presta valves better than Schrader valves?
Schrader valves are more robust and harder to damage Due to the increased diameter of a Schrader valve stem, they're more robust and less prone to bending or damage than a Presta valve. Schrader valves also house their valve core inside their stem, making it harder to damage the core when inflating a Schrader valve.
Why do mountain bikes use Presta valves?
So why are Presta Valves used on mountain bikes? The main reason presta valves are used on mountain bikes comes down to the fact they are compatible with tubeless tires. Being able to get your tires down to a low psi, while maintaining that air is important, and presta valves make that happen.
What is Presta valve used for?
The Presta valve is a bicycle tire inner tube valve of French design found on most road bikes and higher end mountain bikes. The Presta exterior valve pin opens and closes with a small screw top. The Presta valve is thinner and uses a special pump head for inflation.
Do you need a special pump for Presta valve?
To inflate a Presta valve you'll need a regular air pump and a special adapter. These can be purchased for about a dollar at your local bike shop.
Do you need a Presta valve?
Summary. Those nuts they include with Presta valve tubes are unnecessary. I've been riding without using them now for a number of years and have had no problems. Feel free to discard them and shed a couple of grams and have one less thing to worry about keeping track of when you're changing a tube.
Can I switch from Schrader to Presta?
You can switch from Schrader valves to Presta valves by switching to Presta valve tubes. Nothing else is required. Bikes supplied with Schrader valve tubes have larger holes drilled in their rims. Presta valves are thinner so they will fit in the hole drilled for Schrader valves.
How do you pump up a tire with a Presta valve?
How Do You Inflate a Presta Valve without an Adapter?Remove the valve cap. Find the place on the valve cap where it gets smaller. ... Unscrew the valve on the tire.Place the modified cap upside down on the tire and screw it down a few twists.Attach the pump and inflate.
Can you leave Presta valve adapter on?
Just try it without tightening and see how it goes. I rode for months and months on my first set of ust presta valve wheels and never, ever tightened the valve... I just left the adapter on. Once sealant got into the valve stem I had to start closing it fully or it would leak.

Can you inflate a Presta valve without an adapter?
A Presta valve would need a connector to inflate the tire. In this way, you can still use other pumps aside from Presta pumps. With the use of a connector or adaptor, you can use Schrader pumps. Since more manufacturers use Presta valves in their products, cyclists are more inclined to buy a Presta connector.
How much pressure can a Presta valve take?
The valve stem area is the only area sensitive to pressure, and in general the valve can withstand 200 PSI or better. (And if you exceed whatever limit there is the result is "catastrophic" failure, not simply the inability to pump in more air.)
Why do presta valves need to be retired?
Why Presta valves need to be retired. 1. Presta valves are fragile. This is my biggest annoyance. Once a Presta valve stem is unscrewed it’s a whispy, delicate aluminum rod. Bending it, or snapping it clean off happens, and that can ruin a ride. That sucks.
What is the difference between a Schrader valve and a Presta valve?
Typically, the hole in a Schrader valve is larger than that of a Presta valve , which means more air for seating tubeless tires. Regarding tubeless valves, Trek’s Bontrager marketing man Alex Applegate mentions that he likes how Presta “…locks the valve into place on the rim with a nut.”
Does Maxxis have a presta valve?
Maxxis’ marketing guy Bobby Brown acknowledged this, saying: “Presta valves are great since the valve cores can easily be replaced without a proprietary tool, but the valves are more frequently replaced due to damage.”. 2. Presta valves need an adaptor or a special pump.
Is a presta valve better for rear shock?
Presta valves are also supposed to be easier to pump to higher inflations, but that sort of doesn’t add up when you think about a rear shock that routinely sees upwards of 200psi or more. Also, it’s thankfully less of an issue since roadies are starting to come around to the benefits of lower tire pressures.
Do Presta valves have plastic tops?
Both valves have little plastic tops, which aren’t necessary , but do offer a bit of protection and keep dirt out.
What is Presta valve?
Presta valve is a most famous bicycle inner tube valve which is used on high-pressure road bicycles and some mountain bicycles. It is also known as the Sclaverand valve or French valve. This valve has an inner body, a valve cap, and an outer stem.
Parts and Function of Presta Valve
The Presta valve has an inner body, a valve cap, and an outer stem. It also has a lock nut which uses to secure the stem to the wheel rim. The air pumping process of this valve is a little bit difficult due to the small valve diameter. Therefore, it requires a small hole inside the rim.
Construction of Presta Valve
The length of the exterior valve stem varies according to the application’s nature. The diameter of the Presta valve stem is narrower (0.23 inch (6 mm)) than that of Schrader and Dunlop valves (0.32 inch (8 mm)).
How to Use a Presta Valve?
The Presta valves can be inflated with a regular air pump, such as a pump available at gas stations or a portable air compressor. But you will need an adaptor with regular airpump to inflate it.
Where Can I Get a Presta Valve Adapter?
The Presta valve adapter is very small. You can easily shift or carry it from one place to other. Due to its portable feature, it can also lose easily. However, the adapters have low prices. I generally purchase one at a time, one in the bike toolbox and the other in the portable tool bag. It’s not a bad idea to put it in the glove box!
How Do You Check the Pressure of Your Mountain Bike Tire?
Use your hand to check your tire pressure which is one of the short and cheap methods. As you push it, its center must be very stiff, and it should be a little bit out of the tire near the tread. However, manual tests are, of course, not 100% perfect. Such tests can give you some estimation only.
How Do You Inflate a Presta Valve without an Adapter?
If you are in a hurry and don’t have a valve adapter or universal pump, you can use the Presta valve CAP to make an operational adapter. Follow the below-given steps to inflate a Presta valve without an adapter:
Why do mountain bikers use presta valves?
This is a huge reason why mountain bicyclists use presta valves. A huge trend nowadays is to go tubeless, as it helps with lower tire pressures, as well as making a puncture less likely as well.
Can you remove a presta valve to add sealant?
Removing a tire to add sealant can be a pain, however a presta valve can easily be unbolted from a wheel, and you can add sealant to the wheel without removing the tire, and having to struggle with putting it back on.
Can you use presta valves on a mountain bike?
The main downside to presta valves on a mountain bike comes down to the fact that they aren’t as popular for pumps at gas station s, or even some bike pumps.
What is a presta valve?
Presta Valve. The Presta valve is the more slender of the two and is slightly more cumbersome to use, having a locknut instead of a spring to ensure closure. These two features have kept the Presta valve in use on many bicycles. Presta valves are used almost universally on road bikes.
Why are presta valves not easy to pump?
Presta valves are not as easy to pump due to the small diameter of the Presta valve, thus requiring a smaller hole in the rim. The size is important for narrow cross-sectional strength is significantly reduced by the size of the stem hole and in narrow rims such as clincher tires leave where there is insufficient space between tire beads for larger Schrader valves.
What is the difference between a Schrader and Presta valve?
Presta valves adapt to higher pressure than Schrader. Road bike tires often exceed 125 pounds, while Schrader tubes top out at about half that. If your tubes have Presta valves, you need a special pressure gauge made just for Presta valves.
How to check tire pressure with Schrader valve?
If your tubes have Schrader valves, you can check your tire pressure by using a standard car tire gauge. This is much easier than a Schrader valve that requires an object to be inserted into the valve to release air.
How to tighten a Presta valve?
Presta valves need the small head unscrewed (counter-clockwise) before the pump head is placed on to the valve. Then make sure the head is on far enough and pump up your tire. When you remove the valve head, you then need to tighten the small head all the way down , but not overly tight.
What is a Schrader valve?
Bicycles’ from department stores or from the cheaper manufacturers are often fitted with a car tire valve that is also known as a Schrader. Normally, road bikes have a long, skinny Presta valve with the knob on top that screws and unscrews. Presta valves are used only on bicycle inner tubes.
Can you use Presta tubes with valve stems?
However, if you mistakenly purchase Presta tubes with valve stems that are too short, all you can do is to give them to someone who can use them unless you want to go through the hassle of using valve extenders.
