Security & Durability
When it comes to security, the Kryptonite Keeper 785 Lock is a true KEYSTP High Security Bike Lock. The 7mm four-sided chain links are crafted from hardened 3T manganese steel, offering exceptional resistance against cutting and leverage attacks.
Unlike many locks, this one features a patented end link design that secures the chain directly to a hardened deadbolt. This means there’s no weak point where thieves can exploit.
The disc-style cylinder adds extra defense by resisting picking and drilling, common tactics used by bike thieves.
Now, durability matters just as much as security. The chain is wrapped in a weather-resistant nylon sleeve that protects your bike’s paint from scratches.
This sleeve, combined with a durable rubber coating, means you don’t have to worry if you’re riding in wet conditions wearing your rain coat or if your bike rubs against your gear like your sunglass case or other accessories.
The lock’s body is solid, and the entire setup weighs 1.59 kg, striking a good balance between toughness and portability.
