4 pc Wheel Stem & Seatpost Lock kit

Pinhead quick release wheel and seatpost locks protect the front wheel, rear wheel, and seatpost. Once installed, the locks remain permanently on your bicycle, even when you ride. When you need to remove your wheels for servicing, your Pinhead key lets you do this quickly and easily. Pinhead locks cannot be removed with tools such as hammers, pliers, picks, universal socket tools, grinders or bolt cutters. Our convex disc technology prevents your wheels and seatpost from being removed by bike thieves.

Our locks use a special coded key that comes with each lockset. The key is ergonomically engineered to install and tighten your locks, and also serves as a bottle opener. Each key is different, and comes engraved with a nine-digit code so it can be replaced if lost.
