Strengths
- 9mm four-sided manganese links are harder to attack than round-link chain.
- 21.5 in length wraps thick frame + post combos a Mini-7 can't reach.
- Integrated lock head means no separate padlock weak point.
- Sold Secure Gold + $1,750 Anti-Theft Protection Offer is rare at this price.
- Works on ebikes, scooters, and mopeds.
Weaknesses
- 3.90 lbs is heavy to carry on the bike (no frame mount included).
- 9mm is the floor for chain security — fast targets for cordless angle grinders.
- Nylon sleeve eventually frays at link wear points.
- Shorter 21.5 in length is tight for double-locking two bikes.

The KryptoLok 955 Mini is Kryptonite’s mid-tier chain — the right answer when a U-lock can’t reach the anchor. Lamp posts, parking meters, fat-tire ebike frames with thick downtubes, scooter stems — places a 7-inch U-lock won’t wrap around.
9mm manganese steel chain links with Sold Secure Gold rating, integrated lock head (no padlock weak point), 21.5-inch length. Pairs well with a U-lock for double-locking: U through the frame, chain through both wheels.
Kryptonite now has three locks in this catalog: Fahgettaboudit Mini U-lock (10/10), Evolution Mini-7 U-lock (7/10), and KryptoLok 955 chain (6/10). U-lock for fixed posts, chain for irregular anchors.
