How To Lock Your Bike

Just had my chain (NOT a chain used as a lock I hasten to add, the actual chain) stolen from Specialized in Camberwell. Did not expect that. Wheels kicked in before, even would expect a wheel pinched... not the chain. And the frame got irrepairrably bent in the process of its removal... apparently.

Thats really shit.

From my experience they were probably trying to steal your bike, gave up and thought "fuck it, lets trash it instead". Saw a teenager do that to a bike in New Cross Gate a few years ago. They probably took the chain to use as a weapon.

Fahg through the rear and wheel and another abus d lock for the frame to the front?
That be suitable in central london?

I have a bit fuck off Abus Granite for rear wheel and frame and a smaller Abus D lock for front wheel to frame. Has worked for me so far.
