              Description

              This inner tube is suitable for 650 diameter, 28 to 42 section tyres with a 48mm Presta valve.

              How to choose an inner tube:

              To take proper care of your bike, it's important to know the exact dimensions of your tyres.This information is given on the tyre sidewall (diameter and cross-section). For example, 26 x 2.20 means a tyre with a 26-inch diameter and 2.2 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means a tyre that is 50 mm wide and has an inner diameter of 559 mm (approx. 26 x 2.00).

              To remove your inner tube, you'll need the following tools:

              Effortlessly remove your inner tube using our B’TWIN tyre levers.

              Checks to carry out before installing an inner tube:

              Punctures can be avoided by carrying out a quick inspection of the tyre, rim strip and rim.

              How to change an inner tube:

              Before you start, check our step-by-step video.Pre-inflate, insert the valve correctly in the rim, fit the inner tube into the tyre and avoid pinching it during installation.

              Fitting a tyre:

              Always start by fitting your tyre into position at the valve end, and gently work your way to the opposite end without using tools.

              Inflating a tyre:

              Inflate according to the recommendations marked on the tyre.Keep an eye on the tyre's alignment as you inflate.

              Pro advice:

              Check the pressure to safeguard your tyres and improve your ride.
