The ultimate bike rack! The Ortlieb Rack3 offers you the right solution, whether youre on your way to work, the grocery store or around the world. One unique advantage of this all-purpose bike rack is its compatibility with all Ortlieb attachment systems. Outfitted with convenient mounting elements for the QL3 and QL3.1 systems, the Rack3 allows you to attach all Ortlieb bags directly to your bike without any other modifications. If you want to use the Rack3 exclusively for your QL2.1/2/1 bags, you can easily remove the attachment elements for the QL3.1/QL3 and thereby create even more space for your panniers. The Rack3s double-rail design allows you to attach all bike bags with a QL2.1, QL2 or QL1 system to a top level or a lower level. Selecting the lower level gives you the option of simultaneously attaching a bike basket or a Trunk-Bag to the top of your bike rack and expanding your overall stowage space. Rack3 is suitable for bicycles with wheel sizes of 26and 28.The maximum
