Good level of security from a mid-price lock, really good value
The coolest way to carry a D lock. Mind numbingly simple. Doesn't work if you are wearing lycra
A good security solution for everyday riding
By no means foolproof but a useful additional deterrent.
Good quality, solid chain that's a good choice for the shed
Good protection from attack but you might need a new one when the thieves give up
A very tough locking chain indeed
