Why are Presta valves better?
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.
Which is better Schrader or Presta?
Presta valves also perform better over time compared to Schrader valves, in that they hold air more effectively and don’t degrade as quickly. They can also hold higher pressures, which makes them a must for track cycling where tyre pressures typically exceed 120psi.

How tight should a cycle helmet be?
