Does my bike have Presta or Schrader valves?

For the most part, inner tubes and tubulars on road bikes will use Presta valves, and mountain bikes will use Schrader valves. The visual differences between the two are obvious, with the Presta (pictured above) being slimmer, lighter and having a lock nut to close that you can see on the top.

What’s the difference between a Presta and Schrader valve?

Unlike Presta valves, Schrader valves use a spring-loaded valve core, called a check valve. Presta valves aren’t spring-loaded and instead use a valve core nut that holds the central pin in place. Controlling airflow through the valve is done by tightening and loosening the core nut.

Can you 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 fill a tire with a Presta valve?

To inflate a Presta valve, remove the dust cap, unscrew the brass cap, slide a pump onto the valve as far as it will go and flip up the lever on the pump to secure it in place. Pump away until your tire is inflated. Then, remove the pump, screw the brass cap back into place and replace the black dust cap.

How do I know if my rims are Presta or Schrader?

A Presta-only pump has a rubber gasket in the head, or chuck, that will fit snugly around a Presta valve but not a Schrader. A Schrader-only pump has a pin in the center of the chuck to depress the Schrader stem’s check valve.
