The key operated version of the Hammerhead 230 U-lock features Squire’s highest security rating and thus offers maximum protection from theft. The powerful name already indicates the high security standard the Squire Hammerhead 230 U-lock offers. More than one and a half kilograms of massive steel in U-shape are locked with a robust locking mechanism, using a key. This lock is certainly not suitable for road cycling, yet perfect to secure high-quality bikes for long term parking. A wide shackle clearance and large inner dimensions leave enough space to secure your bike to solid objects and protect it from theft. The robust design shows every thief at first glance: You have no chance. Whether you use a hammer, pliers or a saw.

Yet, it is not only the impact- and saw-resistant material of the robust U-lock that helps resist attacks. The plastic-coated body with double locking mechanism firmly holds the shackle on both ends, while the anti-picking cylinder keeps it in position. Even though the U-lock weighs around 1600 grams, it can be fitted securely and rattle-free to the frame mount. Those who prefer increased protection instead of a low weight should go for the Squire Hammerhead 230 bike lock.
