Description
Long Live Aero
It’s hard to beat the sensation of power that comes from a great aero bike. What rider is ambivalent about a machine that is designed to give back free watts? Is there a competitor who doesn’t grasp every last advantage in the battle for speed?
Orca Aero is built for pure speed and efficiency, with aerodynamic shaping, exceptional power transfer, and razor-sharp handling. Its race-focused geometry puts you in the perfect position to push harder, ride faster, and hold nothing back.
Advanced Aerodynamics
Aligning the frame with the airflow, optimizing cross-sections, smoothing transitions and myriad other improvements mean a big reduction in drag.
Power and Precision
There’s no doubt about it—a frame that’s stiff in the right places transfers more of your watts to the rear wheel. Your power, converted to speed. That same stiffness also delivers razor-sharp handling, giving you precise control when it matters most—whether you're cornering at speed or holding your line in a sprint.
Dynamic Race Handling
Race-focussed geometry and ergonomics put you in the perfect place to perform at any speed.
