chain redesign?

just a thought but wouldnt lots of high stength 'strands' of cabling be alot better than a standard chain? it's flexible enough to go through the frame. A normal chain you can cut with bolt cutters pretty easily, with high tensile strands they compress into each other as the bolt cutters tighten down (you've gotta try and mentally picture it in your head) so the surface area the bolt cutters are pressing on spreads the load out as well as gets smaller.

the middle one isn't going to be flexible enough to physically carry with you on the bike (should wrap around the bike easily enough at home or in the garage). So why not make them in the shape of a chain (like the 1st pic)

I think these things use a similar weave design (obviously much much thicker and you don't want the strands quite as rigid and compact as what they use):

I know it's not something you can make at home yourself

theoretically I don't think your design has much against it..

small points to consider..

it would tend to having circular links, or else, it might put the outer strands at the ends of the eliptical loops under more tension than elsewhere. Would perhaps need to get specially made lops that allow the elliptical shape to be maintained while alowing an even tension throughout the strands.

there's also the method of joining the ends of each individual strand within your loops.. else, there will be a single point of failure in every single link.

address those points, and manufacturing costs and you could have something.

can't imagine it would be cheap to manufacture either those normal bike chains are like 80 quid cheapest in the bike shops around here. Would need special machines to do it if their was a way to address those weaknesses.

Good idea in theory. But same old story if someones going to pinch your wheels they will hack through whatever!

Well in Engineering magazine or journal or whatever there was a new design for a bike chain , it was made of this super plastic and had an efficiency of 98.5% and had a much longer life and required no oiling

...oh wait you are on about the security chains
