I have a Beringer wheel on a JS1 and it is a nice piece of kit and has worked and braked fine however, having had my eyes opened by helping a colleague to change the tyre on a colleague's Antares, I wouldn't get one again. If the tyre gets damaged and needs replaced you need to source the expensive 10 ply tubeless aviation tyre and need to have the tyre changing kit (plywood frames + metal spacer to compress the tyre) + lube + new O ring kit. I recently bought all that to take on an expedition to South Africa at total cost in UK over £350 and it took a few weeks to source separately. Without it if I burst a tyre I reckoned I would be stuck on the ground for a long time.

It's fine if you are aware of those aspects and have spares available or can wait to get them if a problem arises.

I would opt for a Tost Penta while which is lighter than standard Tost wheel system (but heavier than a Beringer) and has a hydraulic disc brake but takes normal tubed tyres.
