"Round The World Panniers are designed to bolt directly onto Giant Loop Pannier Mounts (recommended) or other compatible luggage racks using internal frame sheets. These frame sheets feature pre-drilled holes for mounting to GL Pannier Mounts; for other rack systems, additional drilling may be required. Installation requires basic tools and assembly. Please refer to the product instructions for full details. For riders who wish to retain their existing hard luggage rack system, Round The World Panniers can also be mounted to many racks with flat, vertical, hoop-style sides and 16–18 mm diameter tubing, using the rack manufacturer’s hardware. Compatible systems include brands such as Touratech, Happy Trails, SW-Motech, and Hepco & Becker. In addition, some manufacturers—such as Jesse Luggage—offer adapter plates to enable mounting on racks that are not flat and vertical. Confirmed compatible side luggage rack systems include most 16–18 mm round tubing hoops, Yamaha Ténéré 700 OE, KTM PowerParts (1090, 1190, 1290, 790, 890, 390), Royal Enfield Himalayan OE rack, Indian OE single-side luggage carrier, Bumot, ADVM X-Frames, Touratech, Brooks AutoSports, Givi Outback (2019 and earlier, with Givi-specific parts removed), Outback Motortek, Hepco & Becker (Standard and Cutout with GSA Adapter Kit), BMW R1200 GS Adventure, BMW R1250 GS Adventure, BMW F850 GS Adventure (all with GSA Adapter Kit), and Jesse Luggage (with GSA Adapter Kit).
