very nice bike. for a small, relatively unknown company you guys sure do make some quality looking bikes. only thing that "sticks out" for me is how the top-tube bends upward from the head-tube.
what kind of linkage system though? i'm torn between saying Marin's true 4-bar and Mondraker's Zero system. but it looks like a combination between a bunch of them.
Eventually I'll get off my butt and put the technical information on the web site! You are very close in your observation. We use a patent pending new system called Moto*GP Floating Suspension System which floats the shock between 2 parallel rotating links. It is pretty close to an isolated true 4-bar style keeping all braking and pedaling forces separate of the suspension forces.
