Presta Valves vs Schrader Valves

Bicycle inner tubes are either equipped with Presta or Schrader valves. Basically, these two differ in shape and size, but they serve the same function. Take note that bicycle rims work with a specific type of valves, so you should check before you shop. 

The easiest way to identify the type of valve attached to the tubes is to check its shape. Presta valves have a slimmer shape, and they are equipped with a lock nut. Schrader valves look a bit thicker compared to Presta valves, and they come with spring locks. You can contact our team if you’re not sure whether to buy tubes with Schrader or Presta valves.
