Schwalbe AIR Plus AV19AP 29" Tube
Due to the high percentage of pure butyl rubber, the Schwalbe Air Plus hose keeps the air significantly longer. Therefore less re-pumping is required. Thanks to its approximately 70% higher wall thickness, the Schwalbe Air Plus is particularly robust - and thus offers above-average protection against punctures and punctures.

Should the Schwalbe Air Plus ever need to be replaced - it is, like all other Schwalbe tubes, 100% recyclable.

What is a bicycle tube made of?
A bicycle tube is predominantly made of Butyl rubber. Butyl is a very elastic and airtight synthetic rubber. But as with the tire, other fillers are necessary to make up the rubber compound. The quality of a tube can vary significantly depending on the rubber compound. For instance Schwalbe tubes have extremely high air retention and elasticity. This high elasticity allows a wide range of different tire sizes to be covered. There is a difference between heat molded and autoclave tubes. Vulcanizing in a mold improves the uniformity of wall thickness, thus reducing weight and improving air retention. For this reason the autoclave tubes which can be produced easier have become less common over the past years. Schwalbe tubes have always been made using the heat molding process. Every tube also needs a valve, which is bonded to the tube during the vulcanizing process.

Which special features does a Schwalbe tube offer?
Besides the quality of the ingredients, the purity of the rubber compound is decisive for the quality of the tube. Before extrusion, the basic material is forced through a total of seven filters under enormous pressure. All tubes are inserted and inflated into a mold for the vulcanization process. Only this ensures an even wall thickness and high air retention. All tubes are inflated and stored for 24 hours to test for air retention. Afterwards, every tube is carefully checked individually by visual inspection. The Schwalbe tube has been valued by German bicycle dealers for its high reliability for many years. A tube covers many tire sizes through its high elasticity and quality. Tube no. 17 works with tires from a width of 28 mm up to 47 mm - a great advantage for stockholding in the trade. At the same time, it is proof of the quality of the tube. All valves are nickel-plated and threaded. The valve core is always replaceable. Also, Schwalbe tubes with a classic bicycle valve can be inspected for pressure as they have a high-pressure valve core. Every Schwalbe tube is 100% recyclable. Without any loss of quality we can use recycled material in the production of new tubes. We have developed in our own factory a special devulcanization process and for several years, it has proved very successful. Right now every Schwalbe standard tube is made up of 20% recycled old tubes. Taking into account all transport routes, the energy balance is positive. Just a fifth of the energy is used in comparison with the production of new butyl.

Which is the best valve?
There are three types that have become market standards and it is difficult to make any particular recommendation. The most important aspect is that the valve fits the rim valve hole and that an appropriate pump is available. Contrary to popular belief, major air retention differences are now a thing of the past. In any case, all Schwalbe valves provide excellent performance and are adapted to high-pressure use. The classical bicycle valve or Dunlop valve is still the most common worldwide. Most cyclists are familiar with it. The valve core can easily be replaced and air can be released very quickly. Fitting a tube with a Dunlop valve is more awkward, as the valve core and locknut need to be removed in order to fit the valve through the valve hole. Inflation is only possible once the core and the nut are back in place. With traditional Dunlop valves, it is impossible to check the inflation pressure. However, the special Schwalbe Dunlop valve allows a return airflow, so that it is now possible to check the inflation pressure with an Airmax pressure gauge. Formerly it was difficult to inflate a tube with a Dunlop valve, but with today´s modern valve cores, this is no longer the case. The Sclaverand valve is narrower than other valves (6 instead of 8 mm). It needs a smaller rim hole and is therefore particularly well suited for narrow racing bike rims. It is also approx. 4-5 g lighter than a car valve or Dunlop valve. It can be locked manually with the knurled nut. Before inflating, the knurled nut must be loosened. First time users frequently have some problems. Also the thin top pin can be easily bent when attaching and removing the pump connector. Caution: Be aware that using Sclaverand valve tubes on rims with larger valve holes often leads to a valve tear off when the sharp metal edges around the valve hole cut the valve stem off the tube. The Auto/Car valve can be inflated very easily at a filling station and is pleasantly unproblematic. Older, as well as simple bicycle pumps are not compatible with car valves.
