Kryptonite Evolution Series Disc Lock

This is a compact disc lock, which is primarily designed to secure a brake rotor or wheel rather than locking a frame to a bike rack. Because of its small dimensions, it is best used as a secondary security measure alongside a larger U-lock or chain.

The 14mm hardened steel shackle is designed to fit most standard bicycle brake rotors. However, we recommend checking the size of your rotor's ventilation holes to ensure the shackle can pass through comfortably before purchasing.

The reminder cable is a simple, effective tool to prevent you from accidentally riding off while the lock is still engaged. You attach one end to the lock and the other to your handlebar, serving as a visual cue that the bike is still secured.

The lock features a double deadbolt mechanism and reinforced anti-drill and anti-pull protection. This construction is specifically engineered to resist leverage attacks and cutting attempts, providing a high level of security for its size.

The integrated light in the key is designed for convenience during nighttime use, but it is not intended to be user-serviceable. If the light stops functioning, the key will still operate the lock mechanism perfectly fine.
