650x18-25 Bike Inner Tube - Presta

To take good care of your bike, it\'s important to know the exact dimensions of your tyres.This info appears on the tyre sidewall (diameter and section).For example, 27.5 x 1.90 means a tyre with a 27.5-inch diameter that is 1.90 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-584 means your tyre is 50 mm wide with an inner diameter of 584 mm (27.5 x 2.00).

Adhere to the pressure shown on the sidewall.Make sure the tyre settles into place evenly as you pump.

Start mounting the tyre at the valve. Finish mounting the tyre opposite the valve to avoid pinching the inner tube. Never mount your tyre with a tool or a tyre lever, as you risk pinching and puncturing the inner tube.

Keep your tyres in mind:check their pressure before each ride to prevent any problems.
