Comparison

D-lock vs chain lock

A D-lock and a chain do different jobs. The Mini-7 is the lock you take on the bike. The New York 1410 is a 4.9 kg Gold chain for when a compact lock cannot reach the only solid object. Using both is common. Commuting with the chain is not.

The Mini-7 is for carrying on a commute.

The 1410 is for extra length at home.

A U-lock is for a tight stand. A chain is for extra length. That is the main difference.

The Evolution Mini-7 is what you take on the bike: 1.61 kg, a clip, Gold. You will carry it. You will not carry 4.9 kg twice a day.

The New York 1410 is 100 cm of 14 mm Gold chain for a home, a garden, a ground anchor, or a post a compact lock cannot close around. Leave it where the bike is stored.

These are not rivals. Careful riders use both and only carry the U-lock. If the compact lock will not close, neither of these is the answer — see the ABUS 540.

Common questions

Can I commute with the 1410?

Not twice a day. 4.9 kg stays by the door.

Does looping the chain twice make it Diamond?

No. It can reduce slack. It does not change the Sold Secure grade, and it does not turn a lamp-post into an approved anchor.
