Ortlieb Twin City Urban QL2.1

The Twin-City Urban is the ultimate 2-in-1 solution for city dwellers and commuters who rely on their bicycles for transportation. You select the bag’s mission by closing the flap on one side or the other. The QL2.1 mounting system allows you to conveniently click the bag onto your bike rack after you detach the shoulder strap. And once you arrive at your destination, simply remove the bag from your rack, fold the flap over to cover the attachment elements, attach the shoulder strap be on your way. Smart dual-purpose design! And when you appear at the office, no one will suspect that your bag is anything but stylish shoulder bag.
