Proven Schwalbe SV15L Tubes and Tyre Levers for most road bikes. Extreme air pressure stability. The rubber compound makes this possible: less air leakage and therefore less to pump. Extremely reliable, and fast to ride. Quality control for safe riding pleasure: each Schwalbe tube is checked twice for air retention in the factory prior to sale.

Air tightness: 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.
