Once the OS-RACK LOOPS are mounted on the rear fender and the OS PACKS of your choice are mounted to the BASE, fitting is quick and easy.
1. Hook-on the two top straps to the OS Rack Loops but leave loose.
2. Loop the two lower straps around the bike frame at the lowest possible position and hook them back to the loops on the strap making them as tight as possible.
3. Stand at the rear of the bike and pull the top straps as tight as possible, taking up the slack until the packs fit tightly to the bike.
4. Hook-on an additional top pack to the Loop Mounts on the OS-BASE and the OS-Rack Loops.
