Chain Lock
Kryptonite Keeper 785 Integrated Chain
$50
The Keeper 785 threads a 7mm hardened steel chain through your rear wheel or around a fixed object and clicks shut with a built-in disc lock that matches the chain body. At 85cm, it is long enough to loop through a rear wheel and around a ground anchor or bike rack but short enough to carry without a dedicated bag. Entry-level chain security that is meaningfully stronger than a cable lock — 7mm hardened steel resists the bolt cutters that defeat most budget chains. The Kryptonite disc lock body is pick-resistant. A genuine step up from nothing for urban parking.
