It’s hard to beat the sensation of powerthat comes from a great aero bike. What rider is ambivalent about a machinethat is designed to give back free watts? Is there a competitor who doesn’tgrasp every last advantage in the battle for speed? Orca Aero delivers theseprizes – along with the willingness to to go all-out, all day, withouthesitation. Long live the bike that balances the emotional and rational desiresinside each of us – Long live Aero.
PERFECT BALANCE
Historically, considering only the threedesign factors of aerodynamics, stiffness and weight rarely yeilds dramaticimprovement. 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 thesetargets, and identifying additional performance factors that allow the rider toincrease efficiency.
AERODYNAMICS
Aligning the frame with the airflow,optimizing cross-sections, smoothing transitions and myriad other improvementsmean a big reduction in drag. Slipping effortlessly through the air, thatinstant feedback of a world-class aero bike. There is no better feeling.
SUPERIOR ERGONOMICS
Our all new OC Cockpit has been designedfor a perfect balance of aerodynamics, stiffness to weight and ergonomics.
FREE SPEED
Building on all of our aerodynamicknowledge. That means thousands of hours of modelling, wind tunnel sessions,and field testing fanatically considering every single component, searching forthe sweet spot for Orca Aero.

HIGH SPEED EFFICIENCY TEST
In this test, we ask riders to maintain aseries of fixed speeds and measure their power output. We use an indoorvelodrome for this so that we have repeatable conditions and keep everythingconstant between runs so that the only change is the aerodynamics. This makesit 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 lateralloads are handled by the lower spine of the frame. The headtube, downtube andchainstays resist twisting. There is no doubt about it, a frame that is stiffin the right places transfers more of your watts to the rear wheel. Your powerconverted to speed.
LOW SPEED EFFICIENCY TEST
In this test, we ask riders to maintain afixed speed on a steep climb while measuring their power output. The higher thepower output for any given speed, the worse the climbing efficiency. By onlychanging the frame and keeping all the other variables constant, we candetermine how efficient the power transfer is for each frame.
BALANCED HANDLING
One of the most important points toconsider when determining geometry is that the bike must be easy to ride. Goingfast isn’t just a by product of good aerodynamics, it requires precise controlover the bike.
Key features:
TOP TUBE AND CHAINSTAYS
Horizontal top tube and chainstays improveairflow.
DOWN TUBE AND SEAT TUBE
Down tube and seat tube profile has beenaerodynamically optimised for 25-28mm tires.
REDUCE TURBULENCE
Single profile transitions between headtube and downtube and the seat tube and seat stays reduce turbulence in theseareas.
REAR WHEEL AIRFLOW
Drag around the rear wheel has been reducedby aligning the upper seat tube junction with the airflow.
NEW FORK
New aerodynamically designed fork isoptimised for high profile wheels.
OC COCKPIT
Our new aero handlebar, stem and seatpostreduce drag.
