Fietsbinnenband FISCHER 85134 — 24 inch (61,00 cm) met auto (Schrader) ventiel, ETRTO-conform

FISCHER Inner Tube 24 inch (61.00 cm) with Auto (Schrader) Valve is an inner tube manufactured to ETRTO standards for reliable replacement and repair of compatible 24" bicycle wheels. The tube is designed for bicycles that use a Schrader (auto) valve and is suitable for everyday cycling, commuting and leisure rides. Its construction follows standard dimensions to fit tires and rims specified for 24-inch wheels with the corresponding ETRTO measurements.

Advantages

The inner tube is made to ETRTO-compliant dimensions to ensure consistency with standard 24" tire sizes and rim profiles, facilitating correct fit and safe inflation. The Auto (Schrader) valve provides a wide stem diameter for easy inflation with common air pumps at service stations or floor pumps fitted with Schrader heads. The simple, uniform design enables quick installation and replacement, reducing downtime during roadside repairs or routine maintenance.

Suitable for

• Replacement of damaged inner tubes on 24" bicycle wheels that accept Schrader valves
• Commuting and city bikes with 24" wheels
• Leisure and recreational bicycles where a standard inner tube is required

Key specifications

• Wheel size compatibility: 24 inch (61.00 cm)
• Valve type: Auto (Schrader) valve
• Standards: ETRTO-compliant dimensions
• Intended use: standard bicycle inner tube for road, city and leisure riding

How to use

Remove the wheel from the bicycle and release any remaining air from the damaged tube. Carefully unseat the tire bead using tire levers, taking care not to pinch the rim or tube. Inspect the tire and rim for sharp objects or damage before installing the new inner tube. Slightly inflate the new tube to give it shape, insert the valve through the rim hole, and position the tube inside the tire. Reseat the tire bead evenly around the rim, then inflate to the pressure recommended on the tire sidewall using a pump compatible with Schrader valves. Check that the tire sits evenly on the rim and that the valve is straight before finishing with a final pressure check.

Recommendations

Use a pump head or adapter compatible with Schrader valves, and set tire pressure according to the tire manufacturer’s recommendation. Inspect the tire and rim for embedded debris or sharp edges before fitting a new tube. When performing roadside repairs, avoid over-tightening valve cores and ensure the valve remains perpendicular to the rim to prevent leaks.
