yeah there are too shocks. and yes it kind of is a cool design, i don't think you see that everyday ironhorseridr1. i think the first shock (attached to the swingarm) is attached right at the right spot, so when it bottoms out, the swingarm is about to change the direction in which the force is going (from forwards to downwards) so then the second shock would absorb the downward forces.
On the weekend i tried 3 differentes set ups, only at the end of day i felt happy . It seems thast you are rinding over the "carpet" smooth, quiet. Next race on 17/18 may São Paulo Champ.
Some of my friends were speaking to the owner of the company at the World Champs last year and had a go on it and said that over smooth-ish ground it accelarates like a hardtail, with no bob at all.
