My hunch is that they are just claiming that due to the fea they have done on upper linkage in a vacuum. They eliminated the through bolt fastener from the clevis to the rocker link. It also seems like they may have changed the rocker link from a 2 side isis drive attachment of the arms to more of a modern gxp/dub crank spindle arrangement where it's bonded to one side and the other fastens to the spindle. For sure, this was one of the weakest and most maintenance needy parts of the original M/H series bikes.As a mechanical engineer I can not see any constructive reasons, why the new linkage should make a reasonable change in stiffness. In my opinion, for this it would have been necessary to have a bridge between the both upper chain stays. It will be interesting to see the blue paper which bearing size they have used. Cheers
