So to sum up, the advantages of Presta valves are that they allow a higher air pressure, require a smaller hole in the rim and can be purchased in various lengths to suit the profile of your rims. It's very unusual to see Schrader valves used on road bike tubes and wheels.May 22, 2015
What is the advantage of Presta vs Schrader?
Compared to Schrader valves, Presta valves are ideally suited to bike wheels for many reasons: They require a smaller hole in the rim, which improves rim strength. They're lighter, so high-performance wheels don't need to be counterbalanced for the stem weight in order to spin smoothly.Mar 1, 2021
Why are Presta valves so difficult?
I have never had any issues pumping up my tyres using Presta valves, no matter what pump I use. The only time it has been difficult is when the valve stem was too short for the deep rims I have, so there was no enough stem for the pump head to clamp onto. Solution was to buy a valve extender.Jan 9, 2010
Are Presta tubes better?
Still, for most avid mountain bike riders, the Presta valve is superior. The main reasons for Presta valve superiority are: Presta valves hold air better – so they say. More tube varieties with Presta valves.
Does road bike have Presta or Schrader valves?
Presta valves are more commonly used on skinny road bike tires because they are narrower and require a narrower hole in the rim. ... Presta valves adapt to higher pressure than Schrader. Road bike tires often exceed 125 pounds, while Schrader tubes top out at about half that.
Can I use Schrader instead of Presta?
A Presta tube can be used with a Schrader rim but only with a special adaptor known as Schrader – Presta grommet which fills the space around the new Presta valve and secures it. Without a grommet, the tube may puncture near the valve stem from excessive movement or from pressing against the edges of the entry point.
How do I know if my Presta valve is removable?
On a presta valve there is a wide threaded part that the lock ring attaches to. And a narrower part with the valve lock nut above it that the cap threads onto. If the narrow part has two flat sides to get a tool onto, then it's removable.
What does a Schrader valve pump look like?

Which valve is better Presta or Schrader?
Presta valves are easier to pump than Schrader, because they have no valve spring to overcome. ... In narrow rims, clincher tires also leave insufficient space between tire beads for larger Schrader valves. In contrast, Schrader valves are more robust, universally used, and have an easily removable core.
Why are Presta valves so bad?
Presta valves are fairly fragile things. It's easy to bend the stem once it's unscrewed. They work by the tube pressure being higher than the atmospheric pressure. This causes the valve to be forced closed.
What does a Presta valve do?
The weakest point of a bicycle rim is usually the hole for the valve stem. The smaller hole for a Presta valve makes it possible to have extremely narrow wheels while maintaining sufficient strength in the wheel. The air pressure in an inflated tire holds the inner valve body shut.
Can you interchange Presta and Schrader valves?
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. ... Over time, the Presta valve will move and rub against the larger hole and can become damaged.
