Delivery & Returns

The Pinhead Security Set 4-Pack includes a front and rear wheel skewer, seatpost clamp bolt assembly and headset cap and bolt, all of which use the same security key for installation and removal. The Pinhead component security system stays on your bike permanently, replacing existing quick release or standard hex-bolt secured parts with parts which can only be undone with its unique security key.

This system makes sense for several reasons: if you have quick release wheels, you’ll no longer need to lock through your wheels as well as your frame, saving you time each time you lock your bike up somewhere. The secure seatpost clamp bolt prevents opportunist thieves from whipping out your seatpost and the headset cap and bolt replacement will mean that the fork and stem assembly cannot be removed from your frame with just a hex wrench. If you do need to remove your wheels or make any adjustments to your seatpost or stem assembly, it is quick to use the security key to loosen or remove the Pinhead parts, taking barely any longer than a quick release system.

Keys which are registered with Pinhead can be replaced if one gets lost, and Pinhead offer an extensive after-sales service, including free lifetime replacement of any defective item, online key code registration, and live telephone and online technical support.
