              Description

              This inner tube is compatible with 29" diameter tyres, with a cross-section ranging from 1.90 to 2.50 with a 48 mm Presta valve.

              Choosing an inner tube:

              To take proper care of your bike, it's important to know the exact dimensions of your tyres.You'll find this information on the tyre sidewall (diameter and cross-section). For example, 29x1.90 means that the tyre is 29 inches in diameter and 1.90 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-622 means that the tyre is 50mm wide with a 622mm internal diameter (approx. 29x2.00).

              Removing an inner tube:

              Remove your inner tube using the right tools:B’TWIN tyre levers.

              Checks to make before installing an inner tube:

              Even the slightest damage in the rim strip may damage a new inner tube.Keep your eyes peeled and inspect the whole wheel-tyre setup.

              How to change an inner tube:

              Start by watching our installation video.Slightly inflate the inner tube to give it some rigidity, insert the valve, place it inside the tyre, firmly push it into the rim without getting it stuck.

              Fitting a tyre:

              Avoid tools!Always fit it in starting from the valve, then finishing off by hand on the opposite side.

              Inflating a tyre:

              Check the recommended pressure on the tyre sidewall and take your time when inflating, checking the stability of the tyre all the while.

              Pro advice:

              Properly inflated tyres are your safeguard against puncture by pinching.
