The ACID Trunk Bag CITY 8+16 RILink is compatible with all RILink carriers from ACID and CUBE. Roll-out side pockets and a resizable main compartment mean there's bags of room for your luggage but no excess volume when you don't need it. A handy shoulder strap, plenty of reflective details and a fold-out mesh bottle holder add practicality in spades. We even included a practical rain cover to keep the contents dry and your motivation high when the weather turns.
