Key specifications

How to use

Remove the wheel from the bicycle, deflate and unseat the tire bead to access the old inner tube. Carefully extract the damaged tube, inspect the tire and rim strip for sharp objects, and install the Hama inner tube by slightly inflating it to remove folds before placing it into the tire. Seat the tire bead evenly on the rim, fully inflate to the recommended pressure indicated on the tire sidewall, and check that the tube is seated without pinches or bulges. Refit the wheel and verify proper braking and clearance before riding.

Recommendations

Use a compatible pump with a Schrader valve head and follow the tire manufacturer's recommended pressure range. Inspect the tire and rim for debris before installation and perform routine pressure checks to maintain ride comfort and reduce the risk of pinch flats.
