Any bolt cutters that can handle the underlying chain can probably slice through your maille tube with about as much trouble as they would have with a balsa twig.

I actually believe that it would invrease the risk, as per last post.

From a functionality standpoint, any gains (difficulty/time/cost of cutting/breaking/etc) that you make by adding maille could be more efficiently added by use of a more robust base chain.

Comparing a single chain to a combination of chain and sleeve:
For a given weight, the single chain is stronger and less bulky.
For a given strength, the single chain is lighter and less bulky.
For a given bulk, the single chain is much stronger (but probably heavier).

yeah if you used say a 16mm chain then coated it in a tube of maille they cant apply the jaws of the bolt cutters to the chain or a saw or a grinder without first removing the maille

Why Would they need to remove it? They'd just cut Through it.

It would probably be more difficult to cut through a chain made up of many smaller rings, than a single link of a large chain.

I've tried cutting seals off tractor trailers that were made up of steel rope rather than a bolt, and the cutters had a tough time getting through it.

So, instead of making a sheath for the bike chain, make a whole new one.


I admire its purity. A survivor … unclouded by conscience, remorse, or delusions of morality.

polygonal bike chain is basically what you're thinkin of without realizing it. it's shaped so bolt cutters slip off when attempting to cut it. as far as chain locks go, kyptonite's Fahgettaboudit line is the best you're gonna get (good enough to be insured against theft in manhattan, the only place in the world the rest of their locks don't cover). a real thick, short u-lock through the back wheel and frame is still the best way to go though, with another lock on the front wheel and anti-theft measures against any other part that might get stolen, short of taking them with you when you lock your bike outside a shop, such as with lights.
