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 delivers these prizes – along with the willingness to to go all-out, all day, without hesitation. Long live the bike that balances the emotional and rational desires inside each of us – Long live Aero.
PERFECT BALANCE
Historically, considering only the three design factors of aerodynamics, stiffness and weight rarely yeilds dramatic improvement. Big gains in one area always compromise one or both of the others. The key to building the best aero road bike is finding the balance of these targets, and identifying additional performance factors that allow the rider to increase efficiency.
AERODYNAMICS
Aligning the frame with the airflow, optimizing cross-sections, smoothing transitions and myriad other improvements mean a big reduction in drag. Slipping effortlessly through the air, that instant feedback of a world-class aero bike. There is no better feeling.
SUPERIOR ERGONOMICS
Our all new OC Cockpit has been designed for a perfect balance of aerodynamics, stiffness to weight and ergonomics.
FREE SPEED
Building on all of our aerodynamic knowledge. That means thousands of hours of modelling, wind tunnel sessions, and field testing fanatically considering every single component, searching for the sweet spot for Orca Aero.

HIGH SPEED EFFICIENCY TEST
In this test, we ask riders to maintain a series of fixed speeds and measure their power output. We use an indoor velodrome for this so that we have repeatable conditions and keep everything constant between runs so that the only change is the aerodynamics. This makes it possible to calculate the real-world impact of aerodynamic drag, in Watts, for any given speed.
THE KEY TO POWER TRANSMISSION
The large majority of torsional and lateral loads are handled by the lower spine of the frame. The headtube, downtube and chainstays resist twisting. There is no doubt about it, a frame that is stiff in the right places transfers more of your watts to the rear wheel. Your power converted to speed.
LOW SPEED EFFICIENCY TEST
In this test, we ask riders to maintain a fixed speed on a steep climb while measuring their power output. The higher the power output for any given speed, the worse the climbing efficiency. By only changing the frame and keeping all the other variables constant, we can determine how efficient the power transfer is for each frame.
BALANCED HANDLING
One of the most important points to consider when determining geometry is that the bike must be easy to ride. Going fast isn’t just a by product of good aerodynamics, it requires precise control over the bike.
Key features:
TOP TUBE AND CHAINSTAYS
Horizontal top tube and chainstays improve airflow.
DOWN TUBE AND SEAT TUBE
Down tube and seat tube profile has been aerodynamically optimised for 25-28mm tires.
REDUCE TURBULENCE
Single profile transitions between head tube and downtube and the seat tube and seat stays reduce turbulence in these areas.
REAR WHEEL AIRFLOW
Drag around the rear wheel has been reduced by aligning the upper seat tube junction with the airflow.
NEW FORK
New aerodynamically designed fork is optimised for high profile wheels.
OC COCKPIT
Our new aero handlebar, stem and seatpost reduce drag.
