PitlockSet 04 Front Wheel:

I've had one of these in the front wheel of my bike for almost two years. I obviously don't know if anyone's tried to get the wheel off in that time, but I can tell you no-one has even got close if they have tried. They're pretty straight forward to fit, even if you don't know much about bikes or wheels, the little unique key slots onto my keyring easily and is very portable. Only thing to note is that if you want to unscrew the skewers you need as well as your unique key, something straight and rigid (I normally use an allen key) to use as a lever. To unscrew the skewer once it has been properly tightened, you cannot just insert the key and turn, you need to exert more force, but as I said, an allen key is enough once you slot it through the hole on the key. Overall, these have been a great purchase - saved me having to carry a second d-lock around and make locking and unlocking my bike securely much quicker and simpler. Strongly recommended.

A nice german product. Added protection to my bike.

Easy to use great kit

Very Good device. Compared with the standard QR skewer this certainly makes it a lot more difficult to steal the wheel. Therefore, can continue to use just one padlock which makes life much easier!
