How to use

Remove the wheel from the bicycle and deflate the old tube completely. Carefully unseat one side of the tire bead from the rim using tire levers, then extract the damaged tube through the rim. Inspect the tire interior and rim strip for sharp objects or damage before inserting the new tube. Lightly inflate the new inner tube to remove folds, position it inside the tire, reseat the tire bead on the rim, and inflate to the manufacturer-recommended pressure for your tire. Refit the wheel to the bicycle and verify proper seating and pressure before riding.

Recommendations

Use a correctly sized tire lever set and avoid excessive pinching during installation. Check tire and rim condition before fitting the inner tube and maintain recommended tire pressures to prolong tube life and improve ride safety.
