We will be in touch
I cant see why you couldnt just ghetto this. Espcially for high volume tyres. Just drill another rimhole:) and run a bmx tube inside your existing system at a decent pressure. The smaller tube would sit really tight againt the rim and tyre bead and you then just pump up your tubeless to whatever silly low pressure. Surely the effect would be the same as tubliss system for motorbikes?
I may try this and post back up.
The BMX tube will still inflate to fill the tyre, or at least it will compress the outer tube until they are at roughly the same pressure. The membrane separating the two chambers will need to be non-stretch, similar to a tyre, in order to have different pressures right next to each other.
You would have to somehow get a smaller tyre inside your main tyre to do that - this would then cause problems getting two separate beads to seat in the same wheel and the weight penalty doesn't even bear thinking about. I'd probably not bother...
hmm fair point. could inflate the tube a bit then wrap in gaffer tape.;)
Sounds a bunch of nonsense for no gain
