Choosing an inner tube:
To maintain your bike properly, it is important to know the exact dimensions of your tyres.This information can be found on the sidewall of the tyre (diameter and section).For example, 27.5x1.90 means a tyre with a diameter of 27.5 inches and a width of 1.90 inches.
On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.
For example, 50-584 means a tyre that is 50 mm wide with an inner diameter of 584 mm (i.e. 27.5x1.90).
