In the press launch for MASI's 2011 line, MASI Brand Manager Tim Jackson introduced the new Evoluzione, a full carbon fiber bike with a tapered headset, BB30 and oversized chainstays. From BRaIN's coverage of the launch:
“It’s going to have that integrated stiffness from front to back,” Jackson said of Evoluzione. “There’s really great shape in the tubes to add greater torsional strength, with a bit of flex that’s built into the seatstays that also still resists twisting. It’s the magic carpet ride that we all keep talking about with carbon.”
Pretty sure that's just another way of saying that the bike is "laterally stiff and vertically compliant."
