The new standard for Cross Country Racing. Re-designed hubs for stiffness, butted spokes for lightness, new lighter racing rim.

- 150 g lighter (narrower rim for tyres up to 2,1 inches, butted spokes, titanium parts, milling) for efficiency in steep climbs,

- 10 % stiffer (wider dish, redesign hubs, wider bearings spacing) to reduce energy loss and provide more speed from power input,

- 9 % less inertia (ISM milling, rim lightness) fast accelerations and off turn speed and shorter braking distances,

- shorter spokes and Isopulse rear lacing to reduce tension cycles, balance spokes tensions from side to side, reduce material fatigue and finally improve endurance of the wheel.
