Aero 360º
Speed is built layer by layer: questioning every detail, exploring every angle and relentlessly searching for every advantage.
Free watts, built into the system
Taking Orca Aero to the next step meant rethinking aerodynamics beyond the wind tunnel, examining how rider and machine work together to deliver a claimed 21W saving over the previous bike.
A Different Approach to Aero
With aero performance already highly optimised, meaningful gains require a new approach. Instead of chasing results at a single wind angle, development is focused on real-world conditions, where crosswinds and varying yaw angles dominate.
Head Tube
The sharpest, narrowest head tube possible for a standard fork design reduces frontal area without resorting to complex or offset solutions. This system supports a broader size range, meets UCI regulations, and saves on weight compared to more complicated alternatives. The height is reduced as a result of the lowered bottom bracket.
Fork
The fork is carefully profiled to align with the downtube, ensuring a smooth airflow transition even at varying yaw angles. This approach avoids optimisation for a single head-on condition, preserving aerodynamic efficiency in crosswinds. We maintain enough clearance for a wide range of tire widths, without resorting to oversized fork profiles that compromise aerodynamic performance.
Downtube
A slightly wider downtube is shaped to manage airflow efficiently, ensuring aerodynamic performance is preserved across the frame’s largest surface. Particular focus was placed on performance at 5–20° yaw angles, which account for the majority of real-world crosswind conditions.
Bottom Bracket Keel
Building on the previous Orca Aero frame, we extended the bottom bracket keel to enhance its aerodynamic contribution. This refined lower structure manages airflow around the frame’s underside, reducing drag in a key transition area.
Seat Tube and Seat Post
Strategically moving the Di2 battery to the lower part of the frame allowed us to create a slimmer profile for both the seat tube and seat post. This change reduces drag compared to the previous generation while maintaining structural efficiency through the centre of the frame.
Seat Stays
Slimmer seat stays with lower junction points optimise stiffness and weight while introducing a touch of vertical compliance.
Minimal Rear Dropout Design
A compact rear dropout optimised around the UDH standard reduces weight while improving integration. Discreet Di2 cable routing keeps the rear triangle clean and uncluttered.
Aero in Every Corner
Every piece of the frame has been refined millimetre by millimetre, reducing drag in the highest-impact areas first.
Wind Tunnel Proven
Aerodynamic gains initially developed through CFD analysis on the previous bike are validated in the wind tunnel using fairings. Repeatable, real-world conditions ensure those gains translate into performance riders can experience on the road.
