## Description

Protect your Brooks style saddle from theft, fits horizontally bolted saddles. Unlike traditional locks, with Pinhead locks you can protect specific components on your bike from theft. The unique Pinhead key system means that, unlike competitor locks this type, they cannot be removed with a simple screwdrive.

Once installed, the saddle locks remain permanently on your bike, even when you ride. When you need to remove your saddle for adjustment, your Pinhead key lets you do this quickly and easily. Pinhead locks use a special code key that comes with each lockset. The key is ergonomically engineered to install and tighten your locks. Each is key is different, and comes engraved with a nine-digit code so it can be replaced if lost. With your key code, matching locks can be ordered to protect your other components or other bikes.
