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.

How do you know you need 27.5 inch tubes? 

Not sure whether your bike needs 27.5 bicycle tubes or other tube size? We recommend checking the label on the sidewall of your tyre. The label will tell you the diameter and width range of your bicycle tyre. 

You can also check out the product description of your bicycle from the manufacturer site. Most of the time, they provide detailed description of the bike’s parts, especially the tyres. This method only applies if you’ve never altered your bicycle tyres. 

If you’re still in doubt, you can get in touch with our team. We will guide you in choosing the right type of tube replacement. Typically, the 27.5 inches bicycle inner tubes fit various models and makes of touring bicycle, city bicycle and mountain bicycle.
