Description

The ideal inner tube for your 650, Presta valve, 48mm road tyres.

Choosing an inner tube:

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).

Here are the tools you'll need to change your inner tube:

Remove the old inner tube using B'Twin tyre levers

Checks to make before installing an inner tube:

Before installing an inner tube, always carry out a complete check of the tyre.

How to change an inner tube:

To avoid making mistakes, watch the step-by-step video.Slightly pre-inflate the inner tube, place the valve in its hole, install the inner tube, push it into the rim, without pinching.

Fitting a tyre:

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.

Inflating a tyre:

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

Pro advice:

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

Cheap and reliable

A great product that's cheap and reliable. Had no problems fitting it and getting it to inflate. Just need to show my daughter how to change a inner tube now so she can do it next time.
