## Long description

FISCHER inner tube for 27.5" (650B) wheels, size ETRTO 52-584, with an auto (Schrader) valve. Designed to fit tires approximately 52 mm wide on rims with a 584 mm diameter, this inner tube is intended for standard mountain bike and trekking use. The Schrader valve allows inflation with common floor pumps, car pumps and gas station compressors, making it a practical spare or replacement for routine repairs and maintenance.
Advantages
The tube is made from resilient rubber compound that ensures consistent air retention and resistance to small punctures under normal riding conditions. Its auto valve simplifies inflation and is compatible with widely available pump heads and adapters. The 52-584 sizing provides a snug fit for wider 27.5" tires used on MTB and trekking bicycles, helping to maintain stable pressure and reliable ride characteristics.
Suitable for
 27.5" (650B) mountain bikes with tire width near 52 mm
 Trekking and hybrid bicycles that use 27.5" rims and wider tires
 On-road or off-road repairs as a spare inner tube
 Routine maintenance and tube replacement during longer rides
Key specifications
 Wheel diameter: 27.5" (650B), rim diameter 584 mm
 Tire width compatibility: approximately 52 mm
 Valve type: auto (Schrader) valve suitable for common pumps
 Material: standard butyl rubber for air retention
 Intended use: MTB and trekking
How to use
Inspect the tire and rim for sharp objects or damage before installation. Slightly inflate the inner tube to give it shape, then insert it into the tire and mount the tire onto the rim according to the wheel manufacturer's instructions. Ensure the valve is seated straight in the valve hole, then fully inflate to the pressure range recommended by the tire manufacturer. After inflation, check that the bead is properly seated all around the rim and that there are no pinches or bulges.
Usage recommendations
Use an appropriate pressure for the tire width and riding conditions; regularly inspect the tube and tire for wear or embedded debris; carry a compatible pump or inflator and an adapter if needed for Schrader valves when using certain portable pumps.
