this is nothing new at all, it should be called a bladder and motocross and I have to say Avalanche shocks have been doing this for years years and decades. This is a complicated way of doing it as well, Sorry to be a dick but its true. Plus the surface area of the so called membrane is so small it wouldn't be that sensitive compared to a true bladder technology. sorry again
