XENA XN18 SERIES DISC LOCK
Maximum security for your 2 wheeled investment.

The Xena XN18 Maximum-Security disc lock is manufactured out of carbide-reinforced stainless steel, the XN18 is designed to thwart any attempts at disabling or breaking the lock. Weighing in a pretty hefty 2.9 pounds (considering its 431/48 x 131/44 x 211/44-inch dimensions), the Nightmare lock is constructed in the now-popular slip-fit lock design, with the entire lock body slipping over the disc and enabling every component to be solidly encased in a virtually impregnable unit. Because of this design and the lock's carbide-fortified construction, the lock is basically immune to compressed refrigerant attacks. The lock itself uses a high-security four-pin system that is practically pick-proof, and the key barrel (which removes as a single unit to function as the locking pin, which is 18mm in diameter where it passes through the disc) is also carbide-reinforced stainless steel. The gap for the disc is 7mm, making it large enough to slip over the thickest brake disc enabling the lock to fit the vast majority of bikes on the market.

This Maximum-Security lock also features an 110dB siren alarm controlled by dual shock and movement sensors, which have differing sensitivity according to the mounting position on the disc. Powered by a CR2 3V lithium battery (claimed to last about 8 months under normal use), the alarm module automatically arms itself using two infrared sensors that detect the brake disc when the lock is positioned for use. A flashing blue light on the lock signals that it is armed.
