ABUS 726811 Nutfix Solid Axle Single Bike Lock Silver

Nutfix is the new and stylish solution for securing bicycle components. The nutfix system protects both wheels and the seat post against would-be thieves. The nut is Fitted with a mechanism that only releases the screw below when the bike is on its side. This means it is not possible to access the screw UNLESS the bike is on its side. If the bicycle is locked upright, the nutfix caps cannot be removed and prevent access to the nut, meaning that all your bike components remain securely in place. Nutfix comes in three varieties: complete quick release axles kits, individual axle nuts for Bolt-On wheels, and seat post collars. They each come in a variety of sizes to fit many different bikes, and are available now at first in three colors, red, Black and silver.
