Cyclists, this Saris Locking Hitch Tite is that simple but crucial accessory that gives you serious peace of mind about your expensive bike rack! It's a threaded locking hitch bolt that replaces the standard pin on your Saris hitch rack, turning it into a theft-proof system that keeps your rack securely attached to your vehicle. The package includes the locking bolt and two keys, so you've got a spare just in case. It's compatible with all current Saris hitch racks that use threaded hitch pins (just make sure yours isn't one of the older models with smooth pins). What's really cool is that this is made right in the USA in Saris' Madison, Wisconsin facility, so you know you're getting quality American manufacturing. Installation is straightforward - just remove your existing hitch pin and replace it with this locking version. No more worrying about someone walking off with your bike rack when you're parked at the trailhead or running quick errands. It's one of those simple upgrades that makes a huge difference in security without complicating your rack setup. Whether you're a daily commuter, weekend warrior, or vacationing cyclist, this locking hitch tite ensures your rack stays right where you left it. Your bike rack investment deserves this basic protection that should honestly come standard with every hitch rack purchase!
