Kryptonite Evolution Chain Lock

At 100cm (roughly 3.3 feet), this chain offers enough length to secure your frame and one wheel to most standard bike racks, though it may be a tight fit depending on the rack design and your bike's geometry.

The lock weighs approximately 6.2 lbs (2.8 kg). It is a substantial piece of security gear, so you will definitely notice the weight if you are carrying it in a backpack during your commute.

Yes, the durable nylon sleeve acts as a buffer between the hardened steel links and your bike frame. It prevents the metal chain from scratching or chipping your paint during daily use.

Kryptonite's 8/10 rating indicates this lock is suitable for moderate to high-crime areas and longer lock-up durations. While it is highly resistant to cutting and picking, it is not their maximum security offering, so it is best used as a primary lock for daily commuters.

If your bike is stolen due to the opening of the lock by force, Kryptonite may reimburse you for your insurance deductible or the cost of the bike up to $3,000. You must register your lock on their website immediately after purchase to be eligible.

Yes, the lock comes with three keys, and you can order replacements directly from Kryptonite if you register your key number with them. It is highly recommended to note your key code somewhere safe immediately after unboxing.
