Flexibility on the road! The pannier carrying system converts your pannier into a backpack. It may be combined with any ORTLIEB bike pannier with a QL1 or QL2 mounting system. As always, ORTLIEB offers comfort in every aspect: the breathable carrying system allows air ventilation at the back. The thermo-moulded back surface, padded and adjustable shoulder straps and the chest strap guarantee comfortable fit. To fix the pannier onto the carrying system, its D-rings are simply hooked into the panniers QL hooks at the top, and the buckles are threaded into the edge protector at the bottom. With its low weight, the carrying system can be easily fixed onto the pannier when not in use. Its suitable for Front-Roller and Back-Roller (from 1995 on), Bike-Packer (from 1996 on), Sport-Packer, Bike-Tourer and Bike-Shopper.
