Roll-out side pockets and a resizeable main compartment mean there's bags of room for your luggage but no excess volume when you don't need it. The ACID Panniers TRUNK 8+7 RILink are compatible with all ACID and CUBE luggage racks and come with an adjustable shoulder strap, reflective details and a mesh pocket. We even added a practical rain cover to keep the contents dry and your pedals moving when the weather turns. It's how we roll.
