The Back Roller Classic 40L are a pair of rear wheel panniers from Ortlieb.
Equipped with the Quick Lock 2.1 system, these waterproof and robust panniers can be attached and detached from the bike very quickly. With their 2x 20L capacity, they will allow you to store your belongings in a dust and moisture free way.
The practical roll-up closure allows easy access to the contents and a strap makes it possible to carry the bag as a shoulder bag. The Back Roller Classic 40L also has an internal pocket and reflective elements to improve your visibility to others.
