Bicycle Inner Tube Schwalbe 10400073 Presta Valve 27.5" 53 - 76.2 mm

The Schwalbe 10400073 bicycle inner tube is made primarily of butyl rubber and is designed for 27.5" (650B) wheels with tire widths from 53 to 76.2 mm. It features a Presta valve and is packaged as a single unit weighing approximately 200 g. The tube is heat-molded to ensure uniform wall thickness, improved air retention and consistent elasticity across the usable size range.

Advantages

Made of elastic, airtight butyl rubber with a Schwalbe compound that provides high air retention and good elasticity. Heat-molded construction ensures more uniform wall thickness, reduced weight and better sealing compared with autoclave-produced tubes. The bonded Presta valve is vulcanized into the tube for a reliable connection.

Suitable for

• 27.5" (650B) mountain and trekking bikes
• Tire widths 53 mm to 76.2 mm (suitable range for off-road and wider road tires)

How to use

Fit the tube into the tire and seat the tire bead on the rim before partially inflating the tube to remove folds. Ensure the Presta valve is properly aligned with the rim hole and tighten the valve locknut if present. Inflate to the pressure recommended on the tire sidewall and check for leaks; if necessary, reseat the tire and repeat the check.

Usage recommendations

Check tire width compatibility before purchase and carry a spare Schwalbe inner tube when riding. Use a correct pump with a Presta-compatible head and avoid overinflation beyond the tire manufacturer's recommended pressure.
