Schwalbe Av17 700c Schrader Tube 28-45

What can you say about an inner tube? Here's what Schwalbe say:

Extremely air-tight! Less air loss means having to inflate less. A unique rubber mixture makes it possible.

Extremely reliable! Each SCHWALBE tube is individually examined twice at the factory to ensue air-tightness. Special quality control that prevents unpleasant surprises.
