To be on the safe side, you should secure your bicycle to a fixed object. This way, a thief cannot simply lift your bike and carry it away to break the lock later without being disturbed. The ideal security solution is the ULC 130 insert chain. With this chain, you can lock the frame lock and the chain with just one key. The chain is compatible with AXA frame locks Imenso and Block XXL. It is also suitable for all Abus and Trelock frame locks. The thickness of the chain links is 5.5 mm, and the locking pin made of hardened steel is 10 mm thick. It has a length of 130 cm and a black polyester cover that protects the bicycle from scratches.
