Presta valves are tall and slim, and designed specifically for bicycles. They're usually fitted on more expensive bikes.

Why is my bike pump letting air out?

It is common to lose air while connecting or removing the bike pump. Most of the time, the air will be lost when you remove the pump from the Presta valves. The check valve will hold the air pressure even after removing the handle of the pump. Once you release a valve, the high-pressure air will escape.

Why can't I put air in my bike tire?

There's a little pin that has to be pressed down in order for air to get into the tire, and if it isn't pressed down enough, it won't allow any air in no matter how much you pump. Make sure you press hard enough to fully seat the pump fitting onto the valve.

Is Presta better than 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 do road bikes use Presta valves?

Presta valves are more commonly used because they are narrower, and therefore require a narrower hole in the rim, and the valve hole is the weakest part of the rim. Presta valves also take a higher pressure, which is commonly used in road bike tires.

How do you fill a Presta valve without an adapter?

  • Remove the valve cap. Find the place on the valve cap where it gets smaller.

  • Place the modified cap upside down on the tire and screw it down a few twists.
  • Attach the pump and inflate.
