Top Features of the Zefal Lock'N'Roll QR Antitheft Wheel Skewer - Pair
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.
About Quick Release Skewers
Quick release skewers are rods which are threaded at one end, with a cam assembly on the other. This combines to make a lever operated cam system. The quick release mechanism was invented in 1927 by Tullio Campagnolo, who was an Italian bicycle racer. He was frustrated when he needed to repair a flat tyre during a race, the weather had turned cold, and his hands were numb, so he could not operate the wingnuts which retained the wheel. He had been well-placed prior to the puncture, but lost valuable time, so decided to develop a quick release skewer system which enables simple wheel removal in seconds.
