Solid lock hopefully near indestructible
Good value, best price around, very secure.
Good value, best price around, very secure.
Great lock for around shopping malls for anchoring ip
Recommended by The LPL, no room on my bike for my D lock which is very heavy to carry so I have this very heavy chain lock which I can wrap around my bike.
Bought this after watching the lock picking lawyer on is some bit of kit. Excellent.
Immensely solid lock, chain and the choice of professional lock pickers (YouTube: TheLockPickingLawyer). The 55cm is portable but doesn’t give much reach to fixed posts etc unless you can get your bike right up to it. This 90cm model however gives more flexibility and can wrap round more of your bike with ease (or two bikes), albeit heavier if carrying. Can also register keys for free and Kryptonite will send a replacement if lost (although comes with three to start with). Best price by far for the latest model (Series 4) and next day delivery from Tweeks Cycles.

Far too small. Needs to be at least 40 cm longer
