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.

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

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??

Last I heard external ones were illegal and internals were legal but this is a few years ago...so not sure now

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?
