## Long description

The Continental 28-inch bicycle inner tube is a high-quality replacement component engineered for consistent performance and reliability. Constructed from a premium rubber compound, this inner tube features an even wall thickness that provides excellent resistance to air leakage and punctures. It is designed to maintain optimal pressure over extended periods, making it a dependable choice for daily commuting, touring, or recreational cycling.
Advantages
This inner tube stands out due to its robust construction and high-quality materials, which ensure long-lasting durability across various road conditions. The uniform wall thickness minimizes the risk of weak spots, providing a stable and safe ride. Furthermore, the inclusion of a standard 40mm Dunlop valve ensures compatibility with most traditional bicycle pumps, allowing for quick and easy inflation whenever necessary.
Suitable for
City and trekking bicycles with 28-inch wheels
Commuting and daily urban cycling
Replacement for tyre sizes ranging from 27x1 1/4 to 28x1.75
Cyclists requiring a reliable Dunlop valve system
When it may not be suitable
This inner tube is not compatible with bicycle wheels that require Presta or Schrader valves unless an appropriate adapter is used. It is also not suitable for mountain bikes or road bikes with wheel diameters other than 28 inches or specific ETRTO sizes outside the supported range.
Key specifications
Wheel size: 28 inches
Valve type: 40mm Dunlop (Blitz/Dutch) valve
Material: High-quality rubber compound
Supported ETRTO sizes: 47-622 to 62-622
Wall thickness: Even construction for durability
How to use
To install the inner tube, first remove the tyre from the rim using tyre levers. Inspect the inside of the tyre casing for any sharp objects or debris that may have caused a previous puncture. Slightly inflate the new inner tube to give it shape, then insert it into the tyre, starting at the valve hole. Carefully seat the tyre beads back onto the rim, ensuring the tube is not pinched between the tyre and the rim wall. Once seated, inflate the tube to the recommended pressure indicated on your tyre sidewall.
What to consider before purchase
Verify your current tyre size matches the supported ETRTO range
Ensure your rim is compatible with a Dunlop valve
Check the valve length to ensure it protrudes sufficiently from your rim
Usage recommendations: Always check your tyre pressure before every ride to ensure optimal performance and to prevent pinch flats. Regularly inspect your tyres for wear and embedded debris to extend the life of your inner tube.
