The Swagman Patrol pick up truck bike rack transforms your truck box into a 2 bike carrier. The aluminum telescoping bar is adjustable to any size of truck and the soft padded brackets fit onto pegs that secure the rack to the truck bed rails. The Patrol has a locking cam lever for macro-adjustments and a rotating and locking knob for the final micro-adjustment for easy and secure fit. The rack comes with two Impact fork mount blocks however; the bar could fit added Impacts to transport more than 2 bikes contingent on the handlebar width and heights as well as the size of the truck it is mounted upon. The fork mounts fit 9mm quick release skewers or 15 mm thru axles with the 15mm adaptor core installed. Additional core adapters are available to fit 20 mm and 150mm x 15mm axles. The rack comes with 3 keys that fit all four locks; the locking Impact cylinders that lock the rack to the bike and the locking cam lever and rotating knob which lock the rack to the truck. The Patrol is compatible with trucks with over-the-rail bed liners. It is a favorite product of truck-owning cyclists everywhere and is covered under a Swagman limited lifetime warranty.
