As above has anyone tried these - looks like a neat idea

Yes, been using it for years and it's very popular in the LDT world. Wouldn't use anything else on my enduro or LDT bike. Not relevant for modern trials bikes but could be used nicely on older bikes with tubed rears. 

I use it on my Bultaco (1.85 rim) since 2 years. Make it possible to use tubeless tyres on tubed rims. Running Dunlop D803GP. No rim locks. No wandering inner tube. Must follow the instructions when installing . Good product I think?.

I have used them on my trail bikes, for general riding and for LDTs, for several years. I first started importing them from the USA (before they were available in UK) on recommendation from my son who helped with development test riding out there. I think they're great.

As mentioned by Carl, it is important to follow the instructions when installing. The 'I've been changing tyres for ever and don't need instructions' approach doesn't work.

Additionally, always make sure before fitting that the rim doesn't have any sharp dings or nicks on the outer lip, these could damage the Tubliss bladder as you fit it (that tip doesn't appear anywhere in the instructions).

There are those who will say that they 'don't last' or that they 'failed after x amount of time' That is almost exclusively down to damage caused by bad practice when fitting or, more usually, when removing a tyre that has Tubliss already fitted. If you insert the lever too far it can hook under the Tubliss and then break the bead of the outer reinforced liner.

If you fit them properly, then they are a super piece of kit.

 

Thanks guys, much appreciated and thanks for the heads up on the smarts, I’m going to try one on the rear of one of my Bantams when I next change a tyre, so it will be a Tubliss Dual Chamber tubeless Xlite and Tubed rim. Be interesting to see how it goes. 
Thanks again, cheers Paulmac 

This is the best installation video, from the manufacturer:http://tubliss.com/tubliss/installation 

Personally, I use tyre sealant (Slime or similar) not soapy water. The procedure for that is slightly different but explained on the instruction card that comes with the TUbliss.
