Kryptonite Evolution 1090 Chain Lock

Balanced chain security with extra reach for locking up.

The Evolution 1090 offers a practical combination of flexibility and protection. Its 10 mm hardened steel chain links provide strong resistance to cutting attempts, while the longer chain makes it easier to lock your bike to racks and fixed objects.

The high-security cylinder resists picking and drilling. Housed in the patented, hardened oval lock head and paired with a reinforced end link for added security and stability, this system closes security gaps before they arise.

Designed for daily commutes and city riding, it delivers reliable security in a versatile format.

Kryptonite protection is made for those who demand more than a deterrent, and our lifetime warranty extends beyond the lock itself.
