The Blackburn Outpost Cargo Cage blends a bottle cage and a cargo rack into one super versatile frame-mounted accessory. The 6 mm tubular alloy construction has a 9 lb load capacity for strapping down oversize water bottles dry bags or other oddly shaped items. It mounts to standard water bottle braze-ons hardware not included and silicone-backed webbing makes for grippy tie-downs to keep cargo in place.
