For extra security it is important to secure your bike to a fixed object. This way a thief cannot pick up your bike and take it to a quiet place to open the lock. The ideal solution for that is the ULC 100 Plug-in chain. With this chain you operate the frame lock and the chain with just 1 key. The ULC is a universal chain and fits in addition to the AXA Solid Plus, Defender, Victory, Block XXL, Imenso Large and X Large frame locks, also in other brand frame locks. The diameter of the shackles is 5,5 mm and the hardened steel plug in pin is 10 mm thick. It has a length of 100 cm and has a black polyester sleeve to protect the bike from scratches.
