Our favorite bike security product! Pitlocks are german-made, stainless steel security fasteners to protect the easlily stealable parts of your bike. In addition to locking skewers for quick release wheels, there is also a seat-clamp bolt and (wait for it...) a locking bolt for the the headset's top cap so that not just any joe with an allen key can steal your $800 suspension fork. Keys come in thousands and thousands of unique combinations and engage snugly for proper torqueing, unlike many of the rounded sets on the market.

Lots of different combo sets available.
