Superior aerodynamics for maximum speed.
Stable and balanced so you can concentrate on going fast, instead of worrying about what the bike might do next.

Reversible aero seat mast gives riders a choice between a traditional 73° road bike seat tube angle or a steeper, more aggressive 79° seat tube angle.

Alpha Black aluminum frame modeled after the Ironman-winning TTX.
Highly-shaped top tube provides a 20% increase in lateral stiffness at the head tube (compared to the previous design) and creates structural stiffness so wall thickness, and thus frame weight, can be reduced.
A lowered down tube reduces the gap between the front wheel while the trailing edge of the fork crown integrates smoothly with the down tube. The result is frame and fork interface that presents a virtual continuous surface to the wind for superior aerodynamics.
Internal cable routing enters the frame behind stem to keep frame surface “clean” and maximize aero efficiency
