The Pinhead Security Set 2-Pack is an ideal option for riders looking to make their wheels more secure when locking up in a mid to high risk area. The set consists of a front and rear wheel skewer and a unique key which secures the skewers in the frame - meaning that you can quickly and easily remove your wheels from your frame when necessary, but nobody else can. This system has many benefits over using a separate lock or cable to secure your wheels: you can minimise the amount of locking equipment you have to carry around with you, save time each time you lock up and there is no risk of someone making off with your quick release skewers (this is something which we have heard happen before - there are some sick people out there!).
