This the 16mm Steel Shackle fits on poles and fences and is even usable as a lock for 2 bikes. The inner dimensions of this model THOR are 200 x 105 mm, which gives room to lock your frame to poles, two sets of tires and lock different parts of your frame. Unleash the power of 16mm Steel!



Sometimes things don’t go as planned? That is why SIGTUNA provides not two, but three keys for your lock. If you lose one, no panic: you still have a second reserve. Everyone loses a key once in a while and with three keys you are ensured that you won’t get in trouble losing a key.



There is an old saying in bicycle locking: make sure your lock is better than your neighbours. In other words, the security a lock provides depends also on how it compares to other locks that are close when it comes to anti-theft. Having both a superior SIGTUNA U-lock and a Flex Cable scares thieves to even start on it and they will move on to a bike with only one layer of security.
