How to use

Remove the wheel from the bicycle according to the bike manufacturer's instructions and deflate the tyre completely. Carefully unseat the tyre bead from the rim, avoiding sharp tools that could damage the rim or tyre. Extract the damaged tube through the tyre valve opening and inspect the tyre interior and tread for the cause of the puncture; remove embedded debris. Slightly inflate the new inner tube to give it shape, insert the valve through the rim hole and tuck the tube evenly into the tyre cavity. Reseat the tyre bead around the rim, ensuring the tube is not pinched, then inflate to the tyre manufacturer's recommended pressure. Reinstall the wheel and check for proper seating and any slow leaks before riding.

Recommendations

Carry one spare 26" inner tube with an Auto/Schrader valve on rides for quick roadside repairs. Check the tyre and rim for sharp objects before installing the new tube, and inflate to the pressure range printed on the tyre sidewall. Use a pump compatible with Schrader valves or an adapter if necessary, and inspect the replaced tube after the first few kilometres to confirm correct installation.
