They have a website out. It looks to me as if that adjustment lever from there website has fliud runing through those tubs? Wounldn't that be a realiablity issue with the damper? I sure would hate to take a bath in hydralic fluid. They would be hard to get at, but maybe vurable in a crash?. I think it runs abou the same as a full scotts kit, but they sure do look trick.
My dad has a Bultaco road bike that has a damper somewhat like this, but it uses friction instead. It simply has a long bolt that goes down the steering stem to a thing that looks like a disk brake, you twist the knob on top to adjust it.
