After installation, verify that the tube is positioned correctly between the steel rim and tire, ensuring it is not pinched or clamped.

Once properly installed, the DIRELL bike tubes provide a comfortable and safe ride. The butyl rubber construction absorbs impacts from uneven road surfaces, enhancing your overall cycling experience.
