Supplier Info

A carefree product is the Hermetic-Plus inner tube.
Due to an improved composition, it is now more compact and lighter and, due to the larger butyl part and the thicker wall, absolutely airtight.
The best guarantee against punctures.
The favorite of many bike rental companies because the tire keeps air for a very long time.
Our Freeride and Downhill tires are also particularly strong and voluminous.
With an extra thick wall, they are particularly resistant to snake bites.

- Maximum valve pressure 6 bar (Note the maximum tire pressure of the outer tyre)

Hollandbikeshop.com Tire Chart

Which tire fits which rim?

The so-called ETRTO size (European Tire and Rim Technical Organisation) consists of two numbers:
the first is the width of the tire in millimeters and the second is the diameter of the tire in millimeters.
City bikes usually have tire size 37-622:
a 37 mm width and a 622 mm diameter.
The tire width must match the rim width.
The following chart shows possible combinations of tire widths and rim widths according to ETRTO.
