1. Product Overview
The CYCLAMI TPU Inner Tube is designed for road bikes, offering enhanced durability and a lightweight solution compared to traditional butyl rubber tubes. It is compatible with a range of tire sizes and features an aluminum alloy Presta valve for improved air tightness.
Key Features:
- Multi-Size Compatibility: Suitable for road bike tires 700x18/23/25/28/30/32c with a 45mm Presta valve.
- Advanced Material: Made from high-quality TPU, providing superior abrasion and puncture resistance.
- Ultra-Lightweight: Weighing only 38 grams, significantly lighter than traditional butyl rubber tubes, reducing bike burden and improving acceleration.
- Compact Design: Small size for easy storage and convenient carrying in a saddle bag.
- Reduced Rolling Resistance: Minimizes friction for maximum speed and performance.
- Durable Valve Stem: Features a threaded aluminum alloy metal stem for good sealing and reduced air leakage.
2. Installation Guide
Proper installation is crucial for the performance and longevity of your CYCLAMI TPU Inner Tube. Follow these steps carefully:
Pre-Installation Check:
- Before installation, remove the inner tube from its packaging.
- Inflate the inner tube slightly (no more than 5 PSI) to give it shape.
- Submerge the slightly inflated tube in a basin of water to check for any air leaks. If bubbles appear, indicating a leak, do not proceed with installation and contact customer support. Over-inflating an empty tube (more than 5 PSI) can cause irreversible damage.
- Ensure the inside of your bicycle tire is free from any sharp objects or debris that could puncture the new tube.
Installation Steps:
- Locate the air nozzle hole on the wheel hub and carefully insert the Presta valve of the inner tube.
- Gently guide the inner tube into the wheel hub, ensuring it sits evenly around the rim.
- Begin installing the outer tire onto the wheel hub. This step requires patience.
- If the outer tire is difficult to mount, you may use tire levers. Exercise extreme caution to avoid pinching or damaging the inner tube with the tire lever.
- Once the outer tire is fully seated on the rim, you can begin to inflate the inner tube to the recommended pressure for your tire.

3. Maintenance
To ensure optimal performance and extend the lifespan of your CYCLAMI TPU Inner Tube, regular maintenance is recommended:
- Regular Pressure Checks: Check tire pressure before each ride. Maintain the pressure within the range recommended by your tire manufacturer.
- Inspect for Wear: Periodically remove the tire and inspect the inner tube for any signs of wear, cuts, or abrasions.
- Clean Valve: Keep the Presta valve clean and free of dirt or debris to ensure proper sealing.
- Proper Storage: If storing the tube as a spare, keep it in its original packaging or a protective bag to prevent damage from sharp objects or UV exposure.
4. Troubleshooting
Here are some common issues and their solutions:
- Frequent Punctures:
- Check the outer tire for embedded sharp objects (glass, thorns, etc.).
- Inspect the rim strip for damage or misalignment that could cause pinch flats.
- Ensure tire pressure is within the recommended range; under-inflation can lead to pinch flats.
- Air Leakage from Valve:
- Tighten the Presta valve nut.
- Check the valve core for looseness or damage. If damaged, it may need replacement.
- Ensure the valve is straight and not bent, which can compromise the seal.
- Tube Swelling/Bulging (outside tire):
- This indicates over-inflation of the tube when not inside the tire. This is irreversible damage. Replace the tube.
