Quick Summary
The Kryptonite Evolution 1090 is a bike chain lock with a 3 ft chain and 10 mm steel chain links. It is built for securing bicycles and other ride-on gear, and the lock format gives more reach than a short U-lock style setup.
The lock also includes a nylon sleeve, a sliding dust cover, and 3 keys. If length, key quantity, and the exact lock style matter to your setup, this is the main product to compare.
