Ultimate Keyed Chain Lock

Our Bontrager Ultimate Keyed Chain Lock, in partnership with ABUS, offers top - notch bike security. It features a durable 9mm hardened steel chain, boasting a security rating of 9. This lock is our most secure option. The chain is covered with a fabric sheath that not only protects your bike frame but also gives it a sleek finish.

Using this chain lock is easy. Just wrap the chain around a sturdy object and your bike, then use the key to lock it. When unlocking, insert the key and turn it to open. Keep the key in a safe place to avoid losing it. To maintain the lock, regularly clean it with a dry cloth. Avoid exposing it to extreme weather conditions for long periods. If the lock seems difficult to turn, you can apply a small amount of lubricant.
