Schwalbe AV19 Inner Tubes are engineered for superior air pressure retention compared to competitors. Each tube undergoes a meticulous manufacturing process, including precision inflation and molding for consistent wall thickness and exceptional air retention. Furthermore, they undergo a 24-hour pressure test to confirm their durability.

These tubes offer flexibility and are well-suited for a range of bikes, including mountain bikes, CX bikes, gravel bikes, and more.

• Valve: Schrader (car type), 40mm length

These tubes work with all tyre brands.

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 mould. 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.

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.
