Introduction
This manual provides essential instructions for the proper installation and use of your ZEFAL 13mm Cotton Rim Tapes. These self-adhesive, reinforced braided cotton rim tapes are designed to protect inner tubes from spoke ends and rim irregularities, ensuring reliable performance and preventing punctures. They are engineered to withstand pressure and high temperatures generated during braking.

Product Features
- Width: 13mm, suitable for various bicycle rim types.
- Material: Reinforced braided cotton for durability and heat resistance.
- Self-Adhesive: Designed for quick and easy installation.
- Pre-cut Valve Hole: Simplifies valve stem placement.
- High Temperature Resistance: Withstands heat generated during braking, protecting the inner tube.
Setup and Installation
Proper installation of rim tape is crucial for preventing punctures and ensuring the longevity of your inner tubes. Follow these steps carefully:
- Prepare the Rim: Ensure the bicycle rim is clean, dry, and free from any sharp edges or debris. Inspect the spoke holes for any burrs that could damage the inner tube.
- Select Correct Width: Verify that the 13mm rim tape width is appropriate for your specific rim. Refer to the diagram below for general guidance on rim tape widths for different bike types.
- Locate Valve Hole: Identify the pre-cut valve hole on the rim tape. Align this hole with the valve stem hole on your bicycle rim.
- Begin Application: Starting from the valve hole, firmly press the self-adhesive rim tape onto the rim bed. Work your way around the entire circumference of the rim, ensuring the tape is centered and lies flat without wrinkles or air bubbles.
- Overlap and Secure: Overlap the tape by approximately 2-3 cm (1 inch) at the starting point. Trim any excess tape if necessary. Ensure the ends are securely adhered.
- Final Check: Once installed, run your finger along the entire length of the rim tape to confirm it is smooth, fully adhered, and completely covers all spoke holes.

Operating Principles
The ZEFAL Cotton Rim Tapes function as a protective barrier between the inner tube and the bicycle rim. Once correctly installed, they:
- Prevent Punctures: Shield the inner tube from sharp spoke ends, spoke holes, and any rough edges within the rim bed.
- Distribute Pressure: Help to evenly distribute the pressure from the inflated inner tube across the rim bed, reducing stress points.
- Resist Heat: The reinforced braided cotton material is designed to withstand high temperatures generated by braking, which can otherwise degrade standard rim tapes and lead to tube failure.
No specific "operating" actions are required beyond proper installation. The rim tape performs its function passively once in place.
Maintenance
ZEFAL Cotton Rim Tapes require minimal maintenance. However, periodic inspection is recommended to ensure continued protection:
- Regular Inspection: Whenever you remove an inner tube or tire, inspect the rim tape for signs of wear, tears, or displacement.
- Check Adhesion: Ensure the tape remains firmly adhered to the rim bed. If sections are lifting, re-press them down. If adhesion is compromised, consider replacement.
- Look for Damage: Check for any cuts, abrasions, or thinning of the tape, especially over spoke holes. Damaged tape should be replaced immediately to prevent punctures.
- Cleanliness: Keep the rim bed and tape free from dirt, grit, and moisture, which can affect adhesion and tape integrity.
Troubleshooting
If you experience issues related to your rim tape, consider the following:
- Frequent Punctures:
- Cause: Rim tape is misaligned, damaged, or incorrect width.
- Solution: Remove tire and inner tube. Inspect rim tape for proper alignment, tears, or wear over spoke holes. Ensure the tape fully covers all spoke holes. Replace if damaged or if the width is incorrect for your rim.
- Rim Tape Not Sticking:
- Cause: Rim was not clean or dry during installation, or tape is old/defective.
- Solution: Ensure the rim bed is thoroughly cleaned and dried before applying new tape. If the tape is new and still not adhering, it may be defective and should be replaced.
- Valve Stem Issues:
- Cause: Valve hole in tape is not aligned with rim hole.
- Solution: Realign the rim tape so the pre-cut valve hole perfectly matches the rim's valve stem hole.
