How to use

Remove the wheel from the bicycle and partially deflate the damaged tube to ease removal. Carefully unseat one side of the tire bead from the rim and extract the old tube via the valve opening. Inspect the tire interior and rim strip for remaining debris or sharp objects before installing the new tube. Slightly inflate the replacement tube to give it shape, insert the valve through the rim hole, and tuck the tube inside the tire. Seat the tire bead back onto the rim evenly, then inflate to the manufacturer-recommended pressure printed on the tire sidewall. Reinstall the wheel and check for proper seating and secure braking function before riding.

Recommendations

Maintain recommended tire pressures appropriate for your load and riding conditions and regularly inspect tires for cuts or embedded objects. Keep a compatible pump or adapter for Schrader valves available when carrying this tube as a spare. Replace tubes showing repeated punctures or significant aging to ensure riding safety.
