The RockyMounts LoBall Locking Truck Mount is a solid mounting platform for carrying a single bike equipped with a 9mm quick release skewer. This customizable mounting platform is primarily intended for truck beds, but it also works great attached to trailers and SUVs. Its cast aluminum base features two holes for mounting to a wide variety of platforms. Mounting screws aren't included, but the base holes fit both 0. 25in and 6mm bolts. Please note, the LoBall Locking Mount requires the user to drill holes through the truck bed or installation surface before mounting. The mount features a stainless steel skewer for strength and corrosion resistant use, with a UV resistant locking nylon handle and cast aluminum base. It securely locks your front fork to the mounting surface with its locking skewer and handle. Two included keys give you a spare option, just in case you lose one on the road. And for added peace of mind, the mount's large opening allows you to thread through a cable style lock for deterring theft of your frame.
