Secure, easy to access mounting points for an OS-Base (sold separately). 25 mm Velcro® brand hook-and-loop One-Wrap® reusable ties. Lightweight 6061-T6 alloy rings. Use in conjunction with Kriega OS-Base. Universal-fit for other soft luggage systems. Fitting guide: Select an accessible position on the main bike frame, as near to the foot pegs as possible, avoiding any interference with the exhaust, brake lines or wiring. Pass the strap around the frame and back around through the ring. Pull tight to take up the slack. Ensure the soft "loop" side of the Velcro® brand hook-and-loop webbing is facing outwards. Pass the strap around the frame and keep repeating until the Velcro® brand hook-and-loop webbing is completely attached. Repeat on the other side.
