SCHWALBE AV17 Inner Tubes 700 X 28-45c / 28" 27" Schwalbe Valves (2-Pack)

Schwalbe AV17 inner tubes are designed and manufactured to retain air pressure significantly longer than competitors. Each tube is individually inflated and inserted into a mold to ensure uniform wall thickness and excellent air retention, and then stored under pressure for 24 hours to test air retention. Fits all tire sizes:

27 x 1-1/2 (40-609). 700 x 28c (28-622) (28 x 1.10). 700 x 30c (30-622) (28 x 1.20). 700 x 32c (32-622) (28 x 1.25). 700 x 35c (37-622) (28 x 1.40). 700 x 38c (40-622) (28 x 1.50). 700 x 40c (62-622) (28 x 1.60). 700 x 45c (47-622) (28 x 1.75). 27 x 1-1/4 (32-630). 700 x 38B (40-635) (28 x 1-1/2).

Airtight: Schwalbe tubes retain air pressure for a significant period of time. The quality of the rubber mixture and the purity of the material directly affect the quality of the tube. Each Schwalbe tube is individually inflated and inserted into a mold. This ensures uniform wall thickness and excellent air retention. [Reliable] Consistent quality control ensures safe use: Each tube is inflated at the factory and stored under pressure for 24 hours for air retention testing. Group Tube System: The high elasticity and high-quality materials used in our tubes allow us to cover a vast range of tire sizes. Only the highest quality and most reliable tubes meet this requirement. They retain pressure longer. We tested them against other tubes (including name brands, private label brands, and no-name products). The results were clear: Over 30 days, the other tubes lost approximately twice as much pressure as Schwalbe tubes. Possible reasons: low butyl content or low-quality butyl. Schwalbe refuses to compromise on its standards, even as butyl prices rise on the global market.
