セットアップとインストール
The Quick-Lock2.1 (QL2.1) mounting system allows for easy and secure attachment to most standard bicycle racks. Follow these steps for proper installation and adjustment:
- Adjusting the Upper Hooks: The upper hooks can be adjusted horizontally along the mounting rail to fit your rack's width. Lift the handle on the top of the bag to open the hooks, position them over your rack tubing, and release the handle to secure.
- Selecting Inserts: The QL2.1 system includes various inserts (8mm, 10mm, 12mm) to ensure a snug fit for different rack tube diameters. Select the appropriate size and insert them into the upper hooks.
- Adjusting the Lower Hook: The lower hook prevents the pannier from swinging during rides. It can be rotated and slid along its rail to align with a vertical stay on your rack. Loosen the screw, adjust the hook's position and angle, then tighten the screw to secure.
- Attaching to the Rack: With the upper hooks open (handle lifted), place the pannier onto the top rail of your bike rack. Ensure the lower hook engages with a vertical stay. Release the handle to lock the upper hooks.

Opening and Closing the Roll Closure System:
- 開くには: Unclip the side buckles and unroll the top opening.

- An internal pocket with a zipper is provided for small, essential items like keys, wallet, or phone, keeping them secure and easily accessible.
- Distribute weight evenly between both panniers (if using a pair) to maintain bicycle balance.
