This spacious roll-top rucksack has a padded back, ergonomic shoulder straps and a chest strap and converts effortlessly into a pannier. The shoulder straps can be conveniently stowed in a mesh pocket on the back and secured with a cover that includes a slip-in pocket with a waterproof zip, which is fully removable for easy cleaning. Thanks to the reliable QMR 2.0 fastening system, the 2-in-1 backpack and pannier can be easily and securely attached to your luggage carrier (for round tubes from 8 to 16 mm). Removal is child's play - simply pull the connecting strap that joins the two hooks together. You can also secure the QMR hooks with a small lock (e.g. a TSA lock, not included). This versatile backpack-bike bag combination offers plenty of storage space with a well-organised interior, including a padded laptop compartment for devices up to 13.3 inches, as well as additional outside pockets for your phone, pens and other essentials. The 2-in-1 backpack bike bag can be compressed into three positions on the sides, depending on the load.
