BikeTube 18 innertube

Every cyclist needs it at some point. A flat tire is unavoidable and replacement is often necessary. The BikeTube urban is heavy duty to make sure you can do whatever you did before. Make sure you got one around your wheels, and you always got a spare one with you for when you need it.

Size guide

Innertubes for bicycles can have three different types of valves; Dunlop, Presta or Schrader. Dunlop valves are common used city bikes and e-bikes in the Netherlands. Schrader valves on mountain bikes or bikes with wide tires, and Presta valves are preferred for high-pressure tubes common on road or touring bikes. Choose a valve type that matches your bike pump and select the length in our range from 30 - 80mm, based on your rim depth because deeper rims need longer valves for easy inflation.

Our superlite tubes are made from lightweight butyl rubber to save grams without sacrificing on durability. They're ideal for performance focused riders and also available with removable valves for easy replacement.

Innertube with a Presta valve

Innertube with a Presta valve

This innertube is available with a Presta valve, also known as a French valve. This is essential for road and touring bike enthusiasts. This valve type handles high pressures, but when inflating the innertube with this valve you need to open the valve by unscrewing the nipple on top. It's a go-to choice for cyclists seeking efficient and reliable inflation for their high-performance rides.
