The price is unknown right now as apart from material costs, I have to add a bit of time to the price. I will be doing all the work for the first batch. I hope to find a firm to create a larger production run to get the price down.
The more people hear about these new bladders, the more interest it attracts!
I will offer them to the forum to start with a bit of a discount
As for the valve I intend to remake this. I have made a drawing of an original by reverse engineering.
In the end, the bladders should be virtually indistinguishable from an original. Of course, with that opens the possibility for a bladder to be re-sold as original. To avoid that, I will try to stamp an indelible mark to indicate reproduction.
I will keep you posted!
