The Quick-Lock2.2 system sets new standards in flexibility and user-friendliness for bicycle pannier mounting systems. Thanks to its self-closing attachment mechanism, the QL2.2 hooks can be securely used on luggage racks with tube diameters ranging from 8 to 16 mm. The innovative, tool-free tube diameter adjustment with a practical scale on the upper hooks enables precise and quick adjustment from 10 to 16 mm. Additional inserts are no longer required, making handling even easier and faster. The Quick-Lock2.2 system is not only practical but also highly durable: it allows a maximum load capacity of 12.5 kg per side. Anti-scratch coatings at the hook contact points and along the lower rail protect your luggage rack. Another highlight: all system components are replaceable and expandable. Even older bicycle panniers equipped with the QL2 or QL2.1 system can be upgraded without tools. As usual, this innovative product also stands for the highest quality -- Made in Germany
