Ideal for replacing a worn inner tube during maintenance or roadside repairs, this RFX inner tube offers increased thickness for better mechanical resistance compared to standard models. Check the compatibility with your rim and the required valve length before installation. For a clean installation, use appropriate tire levers and inspect the condition of the bead and rim (edges, burrs, seals) before inserting the new tube.
