Sharing the same technology as the mac daddy SpeedMachine 130, the SpeedMachine 110 is better for skiers looking for a more forgiving forward flex also great pairing for softer skis. While the flex is slightly softer it maintains great lateral rigidity for a solid feel when rolling the skis high up on edge. The SpeedMachine 110 is comparable to the Mach 100 as far as flex and fit goes, just a little bit easier to put on in the cold.
