27.5 x 1.6/1.9 Gravel Inner Tube - Presta Thread

Check all the information indicated on the sidewall of the tyre (diameter and width). 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, 47-584 means your tyre is 47mm wide with an inner diameter of 584 mm (approx. 27,5x1.90).

Remove the old inner tube using a tyre lever.

Check the condition of your tyre and replace it if necessary.Make sure no objects are lodged in the tyre.Check the condition of your rim strip and that it is positioned correctly.A rim strip that is even slightly bent can cause punctures.Check that your rim does not have any other issues that could damage your inner tube

Watch our video before you start.Pre-inflate the inner tube slightly to avoid pinching.Insert the valve, making sure you are using the correct valve for your rim.Put the inner tube entirely inside the tyre so that it fits inside the rim.Take care not to pinch the inner tube when fitting.

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.

Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in PSI or bars, 1 bar = 14.51 PSI).Regularly check that your tyre is in the correct position as you inflate it.

To avoid punctures from pinching and for the best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.
