How to use

Remove the wheel from the bicycle, deflate and unseat the tyre bead, then extract the old inner tube. Inspect the tyre and rim for sharp objects or damage before installing the new tube. Partially inflate the Schwalbe tube to give it shape, insert the valve through the rim hole, and seat the tyre bead evenly around the rim. Inflate to the tyre manufacturer's recommended pressure and check bead seating and valve alignment. Refit the wheel to the bicycle and verify there are no leaks or pinch points.

Usage recommendations

Use a pump or pressure gauge compatible with Dunlop valves and adhere to the tyre sidewall recommended pressure range. Carry this tube as a spare on tours or commutes, and keep a basic puncture repair kit and tyre levers to assist with field replacements.
