Zefal LockNRoll Keyless Antitheft Seat Post

Features:

• Award winning innovative new protection for your bike! The Lock N’ Roll security skewer system from Zéfal 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 saddle and bards with the wheels upwards. If your bike is securely locked upright to a post or rack, Lock N’ Roll cannot be opened and your wheels and seat 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 the wheels and seat off.
