Product descriptionPinhead quick release wheel locks protect both front and rear wheels. Once installed, the wheel 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 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. With your key code matching locks can be ordered to protect your other components or other bikes. All components are precision forged from corrosion-resistant CrMo steel and aircraft aluminium alloys. Pinhead locks are unmatched in quality, and backed by lifetime warranty.
