Schwalbe SV9 Inner Tubes are designed and manufactured to retain air pressure considerably longer than their competitors. Not only is each individual tube inflated and inserted into a mould to ensure that there is even wall thickness and excellent air retention, they are also stored under pressure for 24hrs to test air retention.

  • Valve Type: Presta 40mm
  • Model: SV9
  • Approx weight: 130g per tube
  • Price is for 2 tubes

Fits the following tyre sizes:

  • 24 x 1.75 (47-507 )
  • 24 x 1 1/8 (28-540)
  • 24 x 1 3/8 (37-540)
  • 600 x 28A (28-541)
  • 600 x 37A (37-541)

Airtightness: Schwalbe tubes retain air pressure considerably longer. The quality and the material purity of the rubber mixture directly effects the quality of the tube. Each Schwalbe tube is individually inflated and inserted into a mold. This ensures the even wall thickness and excellent air retention.

Reliability: Consistent quality control brings with it the security of use: Each tube is inflated at the factory and stored under pressure for 24 hours in order to test the air retention.

Group Tube System: The high elasticity and quality material used in our tubes allows a great many tyre sizes to be covered. Only an extremely high-quality and reliable tube is up to this requirement.

Retains pressure longer! In comparative tests against other tubes (including named brands, own-label brands and no name products). The result was clear. Over a period of 30 days the other tubes lost nearly twice as much pressure than Schwalbe tubes. Possible reasons: Less butyl content, or lower quality of butyl. Schwalbe is uncompromising in its standards, despite ever increasing world market prices of butyl.

Presta Valves

Presta valves are a popular choice among cyclists for several reasons. Firstly, their slender design makes them lightweight and ideal for high-performance bicycles, minimizing rotational weight for enhanced speed and agility. Additionally, their construction allows for higher tyre pressures, crucial for road cyclists and other performance cyclists seeking optimal rolling efficiency.
