Yakima

Yakima's Locking BedHead keeps your bike locked and secure in your truck bed. This durable and corrosion-resistant mount quickly clamps (no drilling required) onto the interior lip of your truck bed's rail. The included SKS (Same Key System) cores and keys lock the bike and mount to the truck. A beefy, long-throw (so you don't need to unscrew it to clear fork safety tabs) 9-mm-diameter skewer holds your steed securely. And, padding protects your truck’s finish, too.
