Schwalbe inner tube 29" SCV19 40 mm

29" tube with new Schwalbe Clik Valve (40mm) for 27.5", 28", 29" (ETRTO 40/62 - 584/635). Main features and benefits of the SCV (Clik Valve): Intuitive "Clik" system: the pump head is simply and quickly snapped onto the valve (with minimal force, just two fingers) and is just as easily removed after inflation. This eliminates complicated screwing or soldering. No loss of pressure: No loss of air when putting on and taking off the pump head. Greater air flow: For tubeless applications, it offers up to 50% more airflow compared to conventional galus valves (SV/Presta), making it easier to get the tire on the rim. Easy to use for everyone: Simple handling makes tire inflation easy even for less experienced cyclists. Compatibility and conversion kits. For AV valves, an adapter is required that screws onto them. Backward compatibility (with pumps): the SCV valve can also be emergency inflated with a conventional pump for galus valves (SV) with a deployment mechanism. However, full comfort and "click" function is only achieved with a matching pump head or SCV adapter. Parameters For casing size 40/62-584/622 Dimensions 29",28",27,5" Weight 220 g SCV 40 mm valve
