Ordered a 3 pack but received a 4 pack, as the other was not in stock - no additional charge or hassle!
Special key is reasonably small and easy to carry, kit easy to to fit and looks good on a new Scott bike - happy days

"I bought these to give me peace of mind when locking up my commuter bicycle downtown. Now I don't have to worry as much that my steed will suffer the same fate as those poor skeletons of bikes I see around the city. Carrying the key is not really burdensome and would really come in handy if I have to change a tube, etc. The seatpost lock also works great with my early 80s frame as well." - Justin (verified customer)



This Pinhead security pack offers you the ideal solution to bicycle wheel and seat theft which can be an expensive problem among cyclists, at a fraction of their replacement cost.

Not only do you have the wheel locks, which will save you time as you no longer need to lock through quick release wheels when locking up your bike, as they will already be protected from theft by the Pinhead security skewers, but you have the added security of the Pinhead seatpost clamp bolt preventing opportunist thieves from removing your seatpost from your bike frame, giving you confidence and piece of mind while your away from your bike!
