    Are Beadlocks legal in Australia?

    After reading the Bridgstone article, which mentions the use of internal beadlocks, I am a little confused. I thought beadlocks were illegal in Australia, but am happy to be proved wrong.
    My advice is: not to follow my advice.

    Pretty sure the answer is no, most motor x bikes have them std
    Not sure about internal bead locks as well

    Internal bead locks were also common on many early British road bikes, before tubeless tyres.

    Bit of an old thread but I was interested to read about the inflatable bead locks. I looked at the Staun inflatable bead locks a number of years ago for use on a vehicle being supplied to the Australian Army and even went as far as getting one of our rims drilled for a second valve hole and having a Staun bead lock fitted as a concept demonstrator but we didn't end up going ahead with them. I can remember at the time thinking that surely it wouldn't be that hard to come up with a bead lock that had a single valve that was able to somehow "telescope" in and out to allow you to fill either the bead lock or the main tyre from the same valve. A while ago I saw that this concept has been developed for mountain bikes to allow them to run tubeless setups and they have implemented a single valve that can inflate either chamber (albeit a presta valve and not a schraeder valve). https://www.schwalbe.com/en/procore.html

    Pretty nifty piece of German engineering and it had me thinking that surely this concept could be pretty easily applied to a Schraeder valve on a 4x4 tyre??

    Nah internals aren't because you have to drill a hole for the second valve so it's a rim modification and I don't know of any rims that come with 2 valve holes.
    As far as I know rims that are manufactured with externals are legal.

    Thats what I am led to believe too. I don't even think an engineer will sign off on drilled rims too. But yeah. Rims made with locks from the factory, are o.k.

    Ah, so even though running the internal beadlock can improve the footprint of the vehicle in soft situations it is illegal if a hole has been drilled. I have had a quick look for rims with the two done at manufacture. Surely it wouldn't be too hard for them to be factory engineered, would it?
    My advice is: not to follow my advice.

    If you find some steelies with the second hole drilled from factory let me know. As I like the idea of internal bead locks.
