The Ortlieb Front Roller City Pair gives city bikers greater flexibility. They can be used on both sides on front or rear racks or as single pannier. Highly incandescent 3M Scotchlite material reflectors on the panniers' sides give increased safety in traffic. The major advantage: the urban transport containers do not require any mounting. The innovative QL1fixation system is easy to handle and the bags attach to the rack with one click. Before the first ride, the QL hook distance is adjusted with a no. 3 Allen key and off you go. And if you want more, you will get it: the affordable basics can be upgraded with numerous accessories. Both models are provided with edge protectors having slots for fixing the Ortlieb pannier carrying system. Shoulder straps are available as accessories.
