4. Operating Instructions
4.1 Multi-angle Adjustment
The fender allows for multiple adjustment points to ensure optimal coverage and fit for your specific bike and tire size. You can adjust the overall angle and the mudguard angle, as well as the length of the support rod.
- Overall Angle Adjustment: Use the overall angle adjustment knob to change the main angle of the fender relative to the wheel.
- Mudguard Angle Adjustment: A separate knob allows for fine-tuning the angle of the mudguard itself.
- Adjustable Support Rod Length: The support rod can be adjusted in length from 28-32 cm to accommodate different wheel clearances.

6. Troubleshooting
If you encounter issues with your ROCKBROS Road Bike Fenders, refer to the following common solutions:
| Problem | Possible Cause | Solution |
