Are Presta and Schrader valves interchangeable? Schrader valves typically won’t work on rims that are made for Presta valves, because they’re too wide. You can use a Presta valve on rim that’s made for a Schrader valve, but it’s not advisable. It will work in a pinch, but not good for an extended ride.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.Schrader valves require a larger diameter hole than Presta valves because the valves are wider. Schrader valves need an 8mm hole while Presta valves only need a 6mm hole. The extra 2mm in hole diameter weakens the rim.
Can you replace a Presta valve with a Schrader valve?
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.
Are Presta and Schrader valves the same diameter?
Schrader valves require a larger diameter hole than Presta valves because the valves are wider. Schrader valves need an 8mm hole while Presta valves only need a 6mm hole. The extra 2mm in hole diameter weakens the rim.

What is the difference between a Schrader valve and a Presta valve?
1. Schrader valves use a spring-loaded check 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.
Do I need a special pump for a Presta valve?
Presta valves are a lot narrower and are commonly found on higher end bikes with narrow rims. They are a little trickier to inflate as they use a manual locknut to open the valve for inflation. To inflate a Presta valve you’ll need a regular air pump and a special adapter.
How do you fill a Presta valve with a regular pump?
- Unscrew the screw on the tip of the presta valve.
- Place the valve adaptor on the tip of the valve.
- Engage the pump to inflate your mountain bike tire to your chosen pressure.
- Remove the adaptor and screw the presta valve closed.
What is the advantage of a Presta valve?
Presta valves can hold more pressure and do it more reliably because the air pressure itself seals them tightly. They are also lighter and improve the wheel’s rolling resistance. Plus, Presta valves are easily extendable with adapters, so the same valve or inner tube can be used on different types of rims.
