How to use

Inspect the rim and tire for debris or sharp objects before installation. Partially inflate the FISCHER inner tube to give it shape, then insert it into the tire mounted on the rim. Align the Dunlop valve with the valve hole and seat the valve base securely in the rim. Carefully work the tire bead onto the rim, ensuring the tube is not pinched between bead and rim. Inflate to the tire manufacturer’s recommended pressure, checking that the tire seats evenly and the valve remains straight. Recheck for leaks or bulges before riding.

Recommendations

Store spare tubes in a cool, dry place away from direct sunlight and chemicals. When replacing a tube, also inspect tire tread and rim tape; consider replacing rim tape if damaged. Use a pump compatible with Dunlop valves or an adapter as needed, and follow the tire pressure guidelines printed on the tire sidewall for optimal performance and safety.
