heavyweight chain

danlightbulb

Hello all.

I know not directly mountain bike related but it is for my bike so....

Anyone know of anywhere which sells cheap bulk lengths of heavyweight chain? I'm looking for something similar to the heavyweight chains used to secure motorbikes to ground anchors, but don't want to pay the kinds of prices they charge.

Not too worried about the fabric sheaths as I can thread it through an old inner tube or something.

Thanks

How much are you talking about for 'bulk lengths'?

Could try lifting equipment suppliers (ie cranes) or maybe ship suppliers for anchor chain.

PJB security are the cheapest I've seen for standard lengths of motorbike security chain.

By bulk lengths I just meant cut off a roll, as in buying cable. I.e not pre packaged retail products.

Looking for 16mm chain 2 lots of 2 metres.

B&Q sell bike chains fairly cheap, I use an MC chain as it comes wrapped in a nylon 'cloth' so protecting my frame from it!

Any cheap chains (and an awful lot of expensive ones) will be easily cut with bolt croppers. Strong chains aren't cheap (and expensive chains aren't necessarily strong).

If any retailer can cut it off a roll then it's going to be sod all use as a security chain. Do you really need 16mm links? Those are huge, won't fit through most wheels (assuming you want to secure those as well as the frame), very heavy (like 4.5kg per metre) and will easily damage an ally or carbon bicycle frame if you have a mishap and drop the chain.

Unless you're securing some seriously expensive bicycles (and don't forget that your anchor and padlock need to be at least as strong as the chain) then the 13mm from pragmasis will deter all but the most determined:

Theives are lazy, thats why they steal stuff instead of working. You just need to make your bike more hard work to steal than someone elses

I'd read that 16mm would be the minimum not able to be cut with standard bolt croppers.

So ok the 13mm looks ok but I don't want to pay £80.

Basically it needs to be strong enough that if my garage gets broken into then the insurance is satisfied.

in that case you need a Sold Secure certified chain. All your insurer will be interested in is that it has the correct approval certificate, they wont care what size the links are.
Unfortunately approved locks are expensive.

Forget about getting anything worth having then. The 13mm Pragmasis is Sold secure approved at gold level (bicycle) and silver (motorcycle).

Resistance to bolt cropping is as much about hardening technique and link shape than it is about size - other than Pragmasis and Almax chains, most expensive motorcycle chains are ridiculously easy to cut with bolt croppers (watch some of the vids on the Almax site to see just how little protection you're often buying for well over £100).

If you want to cover your insurance rather than actually protect your bike from theft then find out the minimum they will allow as cover and get that - if you want to do both spend some money if you just want to stop your prized possession being nicked then spend some more.
