The AXA Defender is a high quality frame lock with an innovative design and offers the possibility to insert a plug-in cable or chain into the side of the lock and connect your bike to a fixed object. The Defender ring lock provides optimal protection thanks to the anti-drill cylinder and hardened steel shackle. Thanks to the ergonomic control button, the lock can be operated comfortably. The AXA Defender can be installed in a variety of ways. By default, the lock is mounted with the flexible mounting kit that can be used on any frame tube, but it can also be fixed with a screw from above. Comes with a simultaneous locking Shimano Steps battery lock to replace the existing lock. (Suitable for pannier rack batteries BM-E6000 and BM-E6001)
