High quality tubes from Schwalbe. Valve cores are removable to put in sealant.
A Schwalbe tube is not just a tube.
Airtightness. Apart from the quality of the materials the purity of the rubber mixture is crucial to the quality of the tube. The base material is therefore sieved at enormous pressure through seven filters before being extruded. All tubes are inserted into a mold and inflated for vulcanization to ensure consistent wall thickness and high air pressure retention.
Reliability. All tubes are inflated and stored for 24 hours in order to test for air pressure retention. Afterwards each, individual tube undergoes a careful visual inspection. This special quality control helps prevent unpleasant surprises and is why, over many years, Schwalbe tubes have become highly respected for outstanding reliability by bicycle dealers.
Valve. All valves are nickel plated and threaded and valve inserts are replaceable. Schwalbe tubes with the classic bicycle valve are capable of pressure testing thanks to a high pressure valve seal. Each tube is crowned with a transparent polycarbonate dust cap.
