4. Setup and Installation
4.1 Attaching the Mounting System to Your Fork
The Topeak Quick Release Fork Drybag utilizes a mounting system designed to attach to your bicycle's front fork bottle bosses. Ensure your fork has appropriate mounting points.
- Align the quick release mounting plate (if separate) with the bottle bosses on your bicycle fork.
- Secure the mounting plate using appropriate screws and washers (not included with the bag, typically provided with the bike or purchased separately). Tighten securely, but do not overtighten.
- Verify the mounting plate is stable and does not wobble.

7. Troubleshooting
