Using the Arkel Orca Panniers is a breeze. First, attach them to your bike rack using the Cam - Lock system. Just a few seconds, and they're securely in place. When you need to remove them, it's just as quick. For travel at the airport or when you're done with your ride, you can use the optional shoulder strap by attaching it to the D - rings. To keep your panniers in good shape, avoid overloading them as it might put extra stress on the Cam - Lock and the bag itself. After a dirty ride, simply wipe the panniers with a damp cloth. The plastic protector at the bottom is there to protect the bag from the rack, but check it regularly for any signs of wear. If you notice any issues with the Cam - Lock or other parts, contact our support team for help.
