## Summary description

Inner tube for 28/29" bicycles from FISCHER with an auto (Schrader) valve, compatible with ETRTO sizes 50-622, 54-622 and 57-622. Designed to replace or repair damaged tubes on compatible rims and tyres. Suitable for various city, trekking and mountain bike wheels where the listed ETRTO sizes apply. Provides a straightforward replacement option for maintaining rideability.

## Long description

The FISCHER Bicycle Tube 28/29" with auto (Schrader) valve is an inner tube designed to fit tyre/ rim combinations with ETRTO sizes 50-622, 54-622 and 57-622. It serves as a direct replacement for damaged or punctured tubes on compatible city, trekking and mountain bicycle wheels, giving a simple and reliable option for restoring tyre function. The tube's auto valve enables inflation at common service stations and with standard pumps equipped for Schrader valves.
Advantages
This inner tube offers compatibility across several ETRTO widths for 28/29" wheels, reducing the need to match an exact tyre width when selecting a replacement. The Schrader (auto) valve simplifies air topping at public pumps and many home compressors, while the tube construction focuses on providing a practical balance of durability and ease of installation. Its design supports routine on-bike repairs and workshop replacements without specialised tools.
Suitable for
 City bicycles with 28"/29" wheels and tyres in the listed ETRTO ranges
 Trekking and commuter bikes where a robust Schrader valve is preferred
 Mountain bikes with wider tyres that match ETRTO 50-622, 54-622 or 57-622
 Spare tube kits for roadside repairs and routine maintenance
Key specifications
 Wheel diameter compatibility: 28/29 inches
 ETRTO tyre widths: 50 mm, 54 mm, 57 mm (for 622 mm bead seat diameter)
 Valve type: auto (Schrader) valve
 Intended use: inner tube for bicycle tyres (city, trekking, mountain)
How to use
Deflate and remove the wheel from the bicycle, then carefully unseat one side of the tyre and extract the damaged tube. Insert the new FISCHER tube into the tyre, seat the tyre bead evenly on the rim and partially inflate to ensure the tube is not pinched. Fully inflate to the tyre manufacturer's recommended pressure, checking that the valve is perpendicular to the rim and properly secured. Refit the wheel and perform a short test ride to confirm correct installation and inflation.
Usage recommendations
Check the tyre sidewall for the correct ETRTO sizing before installation and use a pump compatible with Schrader valves. Avoid over-inflation beyond the tyre rating and inspect the tyre and rim strip for sharp objects or damage that could cause repeat punctures. Carry a spare tube and basic repair tools for trips where immediate replacement may be required.
