Camera d'aria per bicicletta FISCHER 85099 per ruote da 28 pollici con valvola Schrader (auto)

FISCHER 85099 inner tube for 28" (700C) wheels with a Schrader (car) valve is a replacement bicycle tube engineered for compatibility with standard rims and tires that accept a wide-diameter valve stem. The tube is intended for city, commuter and touring bicycles where a reliable, easy-to-install inner tube with a car-type valve is required. The product fits 28" tire diameters and provides an airtight seal when installed correctly.

Advantages

The tube offers straightforward installation on rims designed for 28" (700C) tires and a Schrader valve, making inflation with standard bicycle pumps or service station air equipment convenient. Constructed from elastic rubber material, it provides dependable air retention and flexibility to conform to the tire profile. The universal design reduces compatibility issues with rims that use a wider valve hole, and the robust valve stem simplifies inflation and pressure checks.

Suitable for

• City bikes with 28" (700C) wheels that require a Schrader valve
• Commuter bicycles used for daily transport
• Touring and leisure bikes where easy valve access and pumping are needed
• Workshops and mobile repair kits for quick replacement

Key specifications

• Wheel diameter compatibility: 28" / 700C
• Valve type: Schrader (car) valve
• Material: elastic rubber for flexibility and airtightness
• Typical use: road, city and touring tires matched to 28" tubes

How to use

Inspect the tire and rim for sharp objects, debris or damage before installation. Partially inflate the FISCHER inner tube to give it shape, then insert the valve through the rim valve hole and seat the tube evenly inside the tire. Mount the tire bead onto the rim, working around the wheel to avoid pinching the tube. Fully inflate to the pressure recommended on the tire sidewall, checking that the tube seats evenly and the valve is straight. Reinspect the tire and rim after a short test ride to confirm proper installation and pressure retention.

Recommendations

Use a pump compatible with Schrader valves or an adapter for hand or floor pumps. Maintain tire pressure within the range printed on your tire sidewall for optimal performance and puncture resistance. Carry a spare inner tube and basic repair tools when commuting or touring to minimize downtime in the event of a puncture.
