Ever locked up your bike with a U-lock and returned to find your wheels, seat, and handlebars stolen?

You can make sure it never happens again. The Pinhead patented locking fastener system secures your individual bike components from theft. Unlike a conventional U-lock, which only secures your bike frame, the Pinhead component locking systems lock your front wheel, rear wheel, seat, and handlebars to your bicycle frame.*

Each Pinhead locking component replaces the standard fastener (pin assembly or hex nut) that your bike is assembled with. Install the locking components, then forget they’re there. Once installed, the lightweight, durable, unobtrusive Pinhead locking fasteners remain on your bicycle when you ride, protecting your components from theft. If you do need to remove a component for bike maintenance, a unique locking key lets you easily and quickly remove any component.
