Schwalbe Air Plus Inner Tube – 27.5 × 2.1–3.0 | 40 mm Presta Valve
The Schwalbe Air Plus inner tube is a heavy-duty option for 27.5-inch wheels, designed for riders who want increased flat protection and better air retention than a standard tube.
Built with increased wall thickness, the Air Plus tube is well suited for mountain bikes, e-bikes, cargo bikes, and everyday riding where durability and reliability matter more than minimal weight. The 40 mm Presta valve works with standard-depth rims and Presta-compatible pumps.
Key Features
• Heavy-duty construction for improved puncture and pinch-flat resistance
• Designed to maintain air pressure longer than standard inner tubes
