Scott unveiled its new Foil Disc road bike today, touting it as the lightest aero disc brake equipped bike currently available on the market.
CONTROL AND SPEED UPDATE
The new Foil Disc retains the same lightweight and aerodynamic properties as its rim-brake sibling, with the addition of a completely redesigned fork, which features a new one-piece design that allows for both a reduction in weight, as well as an increase in stiffness, while minimizing drag and the effects of crosswinds.
According to Scott, the fork has been completely redesigned to manage the asymmetrical forces of disc brakes and to guarantee a perfect airflow around the brakes. In addition, internal brake cable routing and enough tire clearance to accommodate tires up to 30mm tires – complete the new fork.
The Foil Disc features 12 mm thru axles for both the front and rear, which has become the standard set-up for road bikes, while the head of the front axle has a diameter of 25 mm.
Scott says, this gives more contact surface between the frame and the axle in order to carry the extra load coming from the front brake, while the head of the rear axle remains at 20mm because the loads are smaller. Moreover, the lever on both axles can be removed to enhance both the aerodynamics and the aesthetics of the bike.
The head tube on the Foil Disc features a head-to-toe aero profile, which Scott claims has resulted in improved aerodynamics, especially at low yaw angles. Furthermore, the shape of the leading edge has been optimized with additional carbon layers in order to be as aerodynamic as possible, yielding less air drag around the brakes.
A PF86 bottom bracket, combined with Scott’s patented carbon manufacturing process, a wider profile downtube and a tapered seat tube, further compliments the Foil Disc’s stiffness to weight ratio.
COMFORT ZONE CONSTRUCTION
Scott claims, the Foil Disc’s new low attachment seatstays, which are noticeably thinner than previous models, led to a smoother ride quality, giving the rider greater comfort over rough roads, while simultaneously providing increased vertical compliance.
The frame comes with two different styles of derailleur hangers. One for traditional derailleurs, the other for direct mount derailleurs, which are designed to work specifically with Shimano’s Dura Ace and Ultegra direct mount disc brake set-ups.
According to Scott, its new direct mount hanger also gives more space to remove the wheel, which makes the wheel change both easier and faster.
In addition to the direct mount hanger, Scott has designed the dropouts of the Foil Disc to allow for easier rear wheel changes, wherein the axle is guided into the recesses of the dropouts, which in turn lifts up the wheel and moves it into its proper position.
The head tube on the Foil Disc features a head-to-toe aero profile, which again is said to improve the bike’s aerodynamic properties especially at low yaw angles.
Scott accomplished this by adding addition carbon layers to the leading edge of the head tube, which they say ensures a perfect transition between the Foil Disc’s frame and fork for maximum aerodynamic efficiency.
The Foil Disc features a newly designed integrated seat post clamp as well, which results in a cleaner transition between the seat-tube and the seat post to further ensure maximum aerodynamic efficiency, wherein the bike’s proprietary seat post follows the aerodynamic tube shapes of the frame, while also providing a choice of setback between 5mm or 20mm – for ideal positioning.
SYNCROS AERO RR1.0 COCKPIT
The fully integrated RR1.0 cockpit from Syncros was developed in conjunction with the Foil Disc, which Scott says adds to the aerodynamic excellence of the Foil Disc.
To wit, “its superior aerodynamic properties stem from its aero-optimized shape which includes an F01 profile on the horizontal part of the bar along with state-of-the-art integration possibilities. Full integration of brake cables, mechanical and electronic shifting cables and Shimano’s Di2 junction box ensure a smooth transition between the cockpit and the frame, a clean look and aerodynamic cable routing. Despite the aerodynamic bar design which even features a recess to ensure a smooth transition between the bar tape and the grippy top area of the bar where no bar tape is needed, the Syncros Aero RR1.0 Cockpit has been designed following ergonomic principles. Another major advantage of this integrated carbon cockpit is the ability to specifically tailor the performance of the carbon structure on one piece. Towards the connection with the bar, the stem flares out into a triangulated section which offers a larger contact point for the bar to maximize rigidity and resist twisting.”
Furthermore, by removing the junction between stem and bar, Scott claims it was able to increase the stiffness of the Foil Disc’s cockpit to a level previously unachieved by conventional bar and stem setups, while at the same time reducing weight to an impressive 395g based on 42cm bar and 110mm stem. In addition, while the bar angle is predetermined due to the nature of its one-piece design, Scott says its engineering team was able to select the optimal angle for its integrated set-up based on in-depth analysis and testing.
Additionally, two different mount options ensure that all Garmin head units will be perfectly positioned at front of the cockpit, allowing the rider to easily view ride data at all times.
Specific Aero Spacers were also designed for the Foil Disc in order to achieve a smooth transition between the stem and the frame, which are available is sizes of a 2mm, 5mm, 10mm and 20mm in order to fine tune the stack height of the cockpit.
Scott says, it will also offer its Syncros Aero RR1.0 Cockpit as an aftermarket piece as well. Thanks to a reducer shim it’s compatible with both 1 1/4” and 1 1/8” steerers.
