AERODYNAMIC ADVANTAGE, WATTS HAPPENING
Drag Power (Watts) vs Yaw Angle (Degs)
All tests were run at Drag2Zero facilities at the Mercedes-
Benz Grand Prix Wind Tunnel. Here are the facts:
- 20% drag decrease over round
tube bike
- An average of 4-5% decrease in
drag with rider at 45km/h
- Average of 15-watt power savings
at 45km/h
- Designed aero advantages for YAW angles between
0˚ and 15˚ as the wind is never realized straight on in
the real world
WORLDS LIGHTEST AERO ROAD BIKE
The SCOTT FOIL is built with IMP Technology and HMX
carbon fiber, resulting in the lightest bike in the Aero
Road category at only 840g (1227g for frameset including
frame, fork, seatpost and clamp). That is only 5%
heavier than a SCOTT Addict frame.
fuselage interaction
Every tube in the frame is oriented in relation to the leading edges
of the down tube and head tube, as these are the first points of
contact for any wind influence. The rear stays are oriented 4 degrees
from the seat tube plane to route air from the front triangle
around the rear triangle cleanly, and are constructed with a carbon
layup that additionally results in vertical compliance.
Bottom Bracket area
The down tube flares at the oversize bottom bracket junction
achieving several design goals. This construction adds lateral
stiffness without increasing wall thickness, and the new bottom
bracket mold disperses loads to effectively half the stress on this
crucial junction. The shape of the down tube and bottom bracket
carries seamlessly into the chain stays, further reducing turbulence
and creating an additional aero benefit.

RIDER BENEFITS
- The FOIL provides benefits on mountain and flat
race stages and yields benefits for any rider by
providing the perfect balance of aerodynamics,
stiffness and weight.
- The FOIL frame saves an average of 15 watts of
energy at 45km/h resulting in a 4-5% overall gain on
a flat course.
- FOIL’s IMP carbon construction allows for a lightweight
and stiff structure, perfect for acceleration.
The top tube borrows from prior SCOTT Aero Science work on the
Plasma3 in that the head tube functions as the leading edge and
the tube then gradually transitions in diameter along a horizontal
plane all the way to the seat tube. The recessed, integrated seat
clamp matches the top tube and seat tube shape, avoids creating
turbulence, and conforms to our tail shape principle.
3:1 F01 Fork /
Tapered Head Tube
The fork and head tube junction represents an excellent balance
between the constraints of creating an aero frame and the need for
lateral stiffness in a road racing frame. The fork most closely resembles
a typical 3:1 ratio shape to seamlessly integrate with the head
tube. The fork interfaces with the head tube using a 1 ¼” crown bearing,
promoting lateral stiffness while maintaining the designated
shape of the head tube’s aerodynamic leading edge. Stiffness is
further enhanced by the fork’s carbon layup.
