2. Setup and Installation
The Serfas UNI-BRKT is designed for tool-free installation, allowing for quick and easy attachment to your bicycle's handlebars.
- Prepare the Mount: Ensure the mount is in its open position, ready to wrap around the handlebar. The flexible strap should be disengaged from its locking mechanism.
- Position on Handlebar: Place the mount on your handlebar at the desired location. The mount is designed to fit handlebars up to 31.8mm in diameter.
- Secure the Strap: Wrap the flexible strap around the handlebar and engage it into the locking mechanism on the other side of the mount. Adjust the strap tension to ensure a snug fit. The mount should be firm and not rotate freely.
- Attach Headlight: Slide your compatible Serfas headlight onto the mounting plate of the UNI-BRKT until it clicks securely into place. Ensure the headlight is facing forward and is properly seated.

3. Operating Instructions
Once installed, the Serfas UNI-BRKT allows for easy use and adjustment of your headlight.
- Adjusting Headlight Angle: The mount allows for horizontal and vertical adjustment of the attached headlight. Gently pivot the headlight to achieve the optimal beam direction for your riding conditions.
- Removing Headlight: To remove your Serfas headlight, locate the release tab or button on the headlight or mount (depending on the headlight model) and press it while sliding the headlight off the mounting plate.
- Removing Mount: To remove the UNI-BRKT from the handlebar, disengage the flexible strap from its locking mechanism and unwrap it from the handlebar. The mount can be removed in seconds without tools.
4. Maintenance
To ensure the longevity and proper function of your Serfas UNI-BRKT, follow these simple maintenance guidelines:
- Cleaning: Wipe the mount with a damp cloth to remove dirt and grime. Avoid using harsh chemicals or abrasive cleaners, as these can damage the plastic and silicone materials.
- Inspection: Periodically inspect the mount for any signs of wear, cracks, or damage, especially the flexible strap and locking mechanism. Ensure the metal pin is secure.
- Storage: Store the mount in a cool, dry place when not in use, away from direct sunlight and extreme temperatures.
5. Troubleshooting
If you encounter any issues with your Serfas UNI-BRKT, consider the following:
- Mount is Loose on Handlebar: Ensure the flexible strap is pulled taut and securely engaged in the locking mechanism. The mount is designed for handlebars up to 31.8mm; if your handlebar is smaller, additional shims (not included) might be required for a tighter fit, though the strap should provide sufficient tension for most standard sizes.
- Headlight Not Attaching Securely: Verify that your headlight is a compatible Serfas model. Ensure the headlight is aligned correctly with the mounting plate and pushed firmly until it clicks into place. Check for any obstructions in the mounting grooves.
- Difficulty Adjusting Headlight Angle: Ensure no debris is lodged in the swivel mechanism. If the adjustment is too loose, inspect the mount for wear.
