Installation & Fitting Advice
Important safety tips before installing
Before installing your new inner tube, run your hand around the inside of the tyre casing to ensure no sharp stones, glass, or thorns remain that could puncture the tube.
Fitting Warning: Always use blunt, non-metal tools to fit inner tubes onto the rim. Using sharp objects or screwdrivers can pinch, puncture, or pierce the tube during installation.
