Information about ETRTO size: The ETRTO size is a standard way of labeling tire sizes, developed by the European Tire and Rim Technical Organization. It allows easy verification if a new tire fits the bicycle. The ETRTO is recorded in a format similar to postal codes – e.g.: 100-559. These numbers mean:

• 100 mm – tire width
• 559 mm – internal diameter of the tire, that is the rim size the tire must fit.

Note: The diameter (second number) must match your existing tire – this cannot be changed. However, the width (first number) can vary – you can choose a narrower or wider tire as long as it fits within your bicycle frame.
