Pinhead Quick Release Bike Lock 4 Pack Wheels/Seatpost/Headset Information

Season : C

Brand : Pinhead

Code : PH112

Protect your whole bike with the Pinhead 4 pack lock system.

Different to a traditional lock, Pinhead allow you to protect specific bike compenents from theft. The unique key system means the locks cannot be removed by a simple screwdriver, infact, the complex Pinhead technology means they can't be removed by hammer, pliers, picks, universal socket tools, grinders or bolt cutters either. After the first installation, the locks remain permanently on your bike. However they can be removed or adjusted using your specific Pinhead key.
Each Pinhead lock uses a special coded key that comes with each lockset. The keys are ergonomically engineered to install and tighten your locks, and can also serve as a bottle opener! Each and every key are different, and comes engraved with a numerical code so it can be replaced if lost. With your key code, you can order matching locks to protect other components or other bikes.
Make sure to register your key code at pinheadlocks.com so that if your key is lost, a replacement key can be made for you.
