Kryptonite Ring Lock Plug-In Chain

Yes, this chain is designed specifically to plug into compatible ring locks. It works with both retractable and non-retractable models, but your lock must feature the necessary plug-in port to accept the chain's connector.

While a ring lock alone immobilizes your rear wheel, it doesn't stop someone from lifting or carrying your bike away. This plug-in chain allows you to secure your frame to a stationary object like a bike rack or pole, effectively preventing roll-away and lift-away theft.

The 120cm length provides a good balance between security and portability. It is generally long enough to reach standard bike racks, lamp posts, or railings, though you may need to park closer to the object than you would with a longer, standalone cable lock.

Because it is constructed from 9mm steel links, it has a noticeable weight. However, since it is designed to be used in conjunction with a ring lock, it is often easier to transport than a heavy-duty U-lock and chain combination, as it can be coiled neatly or carried in a bag.

No, this is an accessory chain. It relies entirely on the locking mechanism built into your existing ring lock to secure the chain in place.
