The Tern Pinhead Seatpost Clamp Lockset is designed specifically for the HSD and GSD bike models. These locks provide added security by preventing the removal of your seatposts. Once installed, the seatpost locks remain permanently attached to your bicycle, ensuring continuous protection. When you need to adjust your saddle height, the included Pinhead tool allows for quick and easy adjustments using a 15mm wrench. These locks are designed to resist removal by common tools used by thieves, such as hammers, pliers, picks, universal socket tools, grinders, or bolt cutters. The convex disc technology employed in these locks further enhances their security, preventing unauthorized removal of your seatposts. Each lockset includes a unique key engraved with a nine-digit code, allowing for replacement in case of loss. With the key code, matching locks can be ordered to protect other components or bikes.
