Shrader Valves

Presta Valves
The Schrader valve, of automobile type, is more robust and widespread, bicycles, motorcycles, cars, boats, planes. The spring-loaded closure makes it easy to use at the service station because you just need to turn on the inflator. It can also inflate using a conventional bicycle pump:

  • Easy inflation, use pumps at gas stations without an adapter
  • Solidity
  • Mandatory plug because risk of obstruction 
  • More air loss if the shell is not tight
  • Short valve can sink during inflation
 The Presta valve is thin, narrower than the other valves 6 mm instead of 8. Its small diameter allows a smaller hole in the rim. This is adapted to the narrow rims of racing bikes. It is also lighter than the Shrader valve or the Dunlop valve of about 4 to 5 grams:

  • Allow a higher air pressure
  • Require a smaller hole in the rim
  • Can be purchased in various lengths to suit the profile of your rims
  • Easy to pump
  • Ideal on race bike
  • No cap required
