A bicycle trunk bag gives rear-rack cargo a structured place to travel without putting every item into one open pocket. This ROCKBROS design holds approximately 17L in its regular form and expands to approximately 35L when the side compartments are opened. The expandable sections provide pannier-style space when a ride calls for more gear.
Five compartments, padded storage areas and a removable divider help you separate the contents instead of stacking everything together. A rigid body frame supports the bag shape, while adjustable mounting straps attach it to a suitable rear rack. For stops away from the bicycle, two detachable shoulder straps provide a carrying option. The black bag uses nylon, microfiber and EVA, with a zipper closure and reflective exterior elements. Its water-resistant design is useful for changing weather, but keep sensitive items separately protected when prolonged rain is expected. Check your rack arrangement and strap attachment before loading the bag.
