The ABUS Granit X-Plus 540 U-Lock is the security equivalent of fifty trained guard dogs surrounding your bicycle, keeping it safe from sneaky thieves and brute force bandits alike. Made of high-tensile, tempered steel in the heart of Germany, this heavy hitter will always keep your bike exactly where you left it.

With its indestructible double-pin locking mechanism, you'll be leaving your bike in the sketchiest parts of town without batting an eye. Put all that inside a rubberized, no-scratch shell, and you're looking at one of the best U-locks on the market.
