With the frame lock, in addition to the keyed alike function of ABUS' XPlus key system, you also benefit from other advantages for protecting your bike from theft. The 8.5mm shackle, made from hardened steel, gives a good level of protection against a medium risk of theft. The bike lock also has another locking mechanism. Additional accessories such as the ABUS frame lock chain 6KS/85 or 6KS/100 can easily plug into it. With the code card you have the option of other locks keyed alike to the PRO SHIELD XPLUS™ 5955 frame lock. Then you only need one key for all locks.
Decide for yourself whether you want the lock in the NR or R version. With frame locks that have an R in the product name, the key cannot be removed when the lock is open. It stays put and you don't have to stow it away when you ride your bike. Those who prefer to remove the key can choose the NR version.
