Wheelchair Presta Valve Schwalbe Inner Tube
Schwalbe tubes are designed & manufactured to retain air pressure considerably longer than their competitors.
Availability: In stock
Our tubes are high quality Schwalbe tubes. Be careful of buying unbranded tubes as you may suffer loss of pressure and more regular valve failures or punctures.
The valves are all metal, not part rubber like some others. Part rubber valves can split easily and are more vulnerable to impacts.
A tube is not just a tube
Airtightness. Apart from the quality of the ingredients, 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 mould and inflated for vulcanization to ensure constant 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.
Group tube system. Only high elasticity and good quality allows a tube to cover very many tire sizes.
Valve. All valves are nickel plated and threaded and valve inserts are replaceable. Also Schwalbe tubes with the classic bicycle valve are capable of pressure testing thanks to a high pressure valve seal. And it is plain to see as each tube is crowned with a transparent polycarbonate dust cap.
