Zefal Lock N'Roll QR Antitheft Skewer Set

Zefal Lock N'Roll QR Antitheft Skewer Set: Award winning innovative new protection for your bike! The Lock N'Roll security skewer system from Z?fal is as astoundingly simple as a strong deterrent and security proposition. They work in exactly the same way as a normal skewer, slide through the hub, make sure it's tight and then close the lever – the trick with Lock N'Roll is, when your bike is the right way up, wheels on the ground and saddle upwards, these skewers cannot be opened once locked over.To unlock them, you must invert the bike so it's resting on the saddle and bars with the wheel upwards. If your bike is securely locked upright to a post or rack, Lock N'Roll cannot be opened and your wheels and saddle cannot be stolen, yet you retain the practicality and ease of use of quick release skewers in the event of a puncture, mechanical problem or need to store or transport your bike with wheels and saddle off.
