Schwalbe inner tube 28 SCV17 Aerothan 33/47-622 valve 80mm

1 The new Schwalbe Aerothan 2.0 inner tube

The main change is the switch from an all-plastic valve to an aluminium stem with an external thread. This solves the biggest weakness of previous models:

• Higher stability: The aluminium valve does not bend when the pump is attached and seals better in the rim.
• Compatibility: Thanks to the external thread and aluminium, the tube is fully compatible with digital sensors (e.g. Schwalbe Airmax or Bosch Speed Sensor) and above all with the Clik Valve system
• 2. The revolutionary Schwalbe Clik Valve (SCV)

This valve replaces the classic "release" pin of the Presta valve with an intuitive "snap-on" system.

• No screwing: You simply press the pump head onto the valve (you will hear a "click") and after inflating you just pull it off. No levers, no screwing on the valve head.
• High air flow: It has up to 50 % higher flow than classic valves, which you will appreciate when inflating quickly.
• Backward compatibility: If you do not have a pump with a Clik adapter with you, the SCV valve can in an emergency also be inflated with an ordinary pump for Presta valves.
• No pressure loss: When removing the pump there is no hissing or loss of air from the tube.

Main advantages of Aerothan

• Extreme lightness: It weighs roughly 40 % to 65 % less than standard butyl tubes. This means a significant reduction in rotating weight, which you will feel with every acceleration.
• Puncture resistance: Even though the tube wall is thin, TPU is an incredibly tough material. It is very hard to puncture or "pinch" (so-called snakebite).
• Low rolling resistance: In its properties it comes close to tubeless systems. The ride is smoother and faster.
• Shape memory: Unlike other TPU tubes (such as Tubolito), Aerothan is somewhat more stable and holds its shape better, which makes installation easier.
• Heat resistance: It is approved for use with rim brakes too, which is often a problem with other lightweight tubes because of overheating.
