The Xberg converts from a bicycle pannier into a backpack thanks to the clever fold-up lower half of the back panel. Press studs fix the panel in an up or down position, revealing either the BagFix quick-release system (for attaching to a bike rack) or the deuter Contact back system with ergonomic shoulder straps. A roll-top opening with buckle closure, universal attachment options on the lid, plus further internal compartments make it practical and quick to organize and access contents. Disclaimer: Sand, dust and incorrectly packed bags can make the paint in contact areas become dull or scratched over time. To avoid any chafing, you can protect the frame or rack with foam inserts or protective film before attaching bags or panniers.
