The Evolution of security

Often considered a flexible U-lock, the Evolution Series 4 1090 Integrated Chain is great for tough lock-ups around immovable objects while offering the convenience of a cable lock and providing the strength of a U-lock.

The 1090 Integrated Chain Lock is also an excellent option for locking an e-bike as the chain design provides flexibility to ensure you capture the frame and a wheel.
