Introduction
The Schwalbe AV 7AP (Air Plus) Bicycle Inner Tube is engineered for exceptional air pressure stability and reliability. Constructed with a high proportion of pure butyl rubber, this inner tube significantly reduces air loss, meaning less frequent pumping. Its approximately 70% higher wall thickness provides enhanced robustness, offering superior protection against punctures and flats for a safer and more enjoyable riding experience.
Product Overview
This image displays the packaging for the Schwalbe AV 7AP Air Plus Bicycle Inner Tube. The box is predominantly dark grey with blue accents, featuring the 'SCHWALBE' logo and 'AIR PLUS 20"' prominently. The side of the box lists various compatible tire dimensions, indicating the tube's versatility for 20-inch wheels with widths ranging from 1.50 to 2.40 inches.
The Schwalbe Air Plus tube is designed for 20-inch bicycle wheels and is compatible with a range of tire widths. Its robust construction ensures durability and consistent performance.
Setup and Installation
Proper installation is crucial for the performance and longevity of your inner tube. Follow these steps carefully:
- Preparation:
- Remove the wheel from the bicycle.
- Deflate and remove the old inner tube and tire from the rim.
- Inspect the inside of the tire for any sharp objects (thorns, glass, etc.) that may have caused the previous puncture. Run your fingers carefully along the inside of the tire.
- Check the rim strip (rim tape) to ensure it is properly seated and covers the spoke holes, preventing punctures from spokes.
- Partial Inflation:
Slightly inflate the new Schwalbe Air Plus inner tube until it just takes shape. This prevents it from twisting or pinching during installation.
- Insert Valve:
Insert the valve of the inner tube through the valve hole in the rim. Ensure the valve is straight and fully seated.
- Position Tube:
Carefully tuck the inner tube inside the tire casing, working your way around the rim. Ensure the tube is not twisted or pinched between the tire bead and the rim.
- Mount Tire:
Begin seating one bead of the tire onto the rim. Then, starting opposite the valve, work the second tire bead onto the rim. Use tire levers if necessary, but be careful not to pinch the inner tube.
- Seat Tire and Inflate:
Before fully inflating, push the valve stem up into the tire to ensure the tube base is not trapped under the tire bead. Then, slowly inflate the inner tube to the recommended pressure range indicated on your tire's sidewall. As you inflate, check that the tire beads are evenly seated on the rim.
Compatible Tire Sizes: This inner tube is designed for 20-inch wheels and is compatible with tire widths ranging from 1.50 to 2.40 inches (40-406 to 62-406 ETRTO). Always match the inner tube size to your tire's specifications.
Operating Instructions
Maintaining the correct tire pressure is vital for optimal performance, safety, and the lifespan of your Schwalbe Air Plus inner tube.
- Recommended Pressure: Always refer to the pressure range (PSI or Bar) printed on the sidewall of your bicycle tire. Do not exceed the maximum pressure or go below the minimum pressure.
- Regular Checks: Even with the Air Plus's superior air retention, it is recommended to check your tire pressure regularly, ideally before each ride or at least once a week.
- Benefits of Correct Pressure:
- Improved rolling efficiency.
- Enhanced grip and handling.
- Reduced risk of pinch flats.
- Extended tire and tube life.
Maintenance
Proper maintenance will ensure the longevity and performance of your inner tube.
- Pressure Monitoring: As mentioned, regularly check and adjust tire pressure. The Schwalbe Air Plus tube retains air longer, but consistent monitoring is still beneficial.
- Visual Inspection: Periodically inspect your tires and inner tubes (when removed) for signs of wear, cuts, cracks, or embedded debris. Address any issues promptly.
- Valve Care: Ensure the valve cap is always in place to protect the valve core from dirt and moisture. If using a Schrader valve, ensure the valve core is tight.
- Storage: If storing spare inner tubes, keep them in a cool, dry place away from direct sunlight, extreme temperatures, and ozone-producing devices (like electric motors), which can degrade rubber.
Troubleshooting
Here are common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Frequent Punctures | Sharp objects in tire, worn tire, low tire pressure (pinch flat), faulty rim strip. | Inspect tire thoroughly for embedded debris. Replace worn tires. Maintain correct tire pressure. Replace or adjust rim strip. |
| Slow Air Leak | Small puncture, loose valve core, faulty valve. | Locate puncture (submerge in water), patch or replace tube. Tighten valve core. Replace tube if valve is faulty. |
| Tube Pinched During Installation | Tube caught between tire bead and rim. | Deflate, reposition tube, ensure tire beads are properly seated before full inflation. |
