HDS: Horizontal Dual System
Following the HDS principle, the E-116 frame features lighter, smaller tubes in the upper parts of the frame to absorb road buzz and increase comfort, while the lower areas are built stout and strong, to ensure complete power transfer to the rear wheel.
Whether in training or during a race, HDS construction lessens fatigue thanks to the enhanced comfort while simultaneously maintaining maximum efficiency, losing none of the athlete’s power in propelling bike and rider fast forward.
AFS Triathlon/Time Trial Geometry
The result of long experience and painstaking analysis, AFS geometry ensures the bike remains stable and the steering accurate, even in the most intense effort. The rider can stay on the aerobars in situations where it isn’t advisable to do so with other bikes. Every aspect of the geometry contributes to increased control and an optimal position. Two of these play a particularly decisive role:
- Long chainstays- 400mm long in all frame sizes, they are longer than most of our competitors’ stays. The result is increased stability at high speed as well as crisp, faultless shifting, every time…because time is scarce.
- BB-Drop 75- While our competitors set their bottom bracket at a 70 or even 60 mm drop below the wheel hub centerline, we chose to drop ours a little lower, at 75mm. Why? The lower center of gravity makes for a more stable, solid-feeling ride.
You’re in control.
The best aerodynamic profile can only be achieved when the rider is well positioned on the bike; this is what AFS guarantees.
In the world of time trial events, much emphasis is placed on the aerodynamic properties of bikes. While this is an important factor, in reality the cyclist generates up to 70% of the aerodynamic drag. This fact is at the core of Argon 18’s design philosophy. Our approach is that the rider and bike must form an integrated unit in order to optimize efficiency and achieve the best results. CFD analysis clearly demonstrates that once the rider is not in proper position, drag increases dramatically. Optimal positioning through AFS gives the rider the ability to remain on the armrests in the proper aero tuck position longer.
AFS geometry built into the E-116 guarantees tremendously accurate steering and extremely stable handling. This allows the rider to remain on the armrests in circumstances where it has not always been possible. For example, riders can remain in the perfect aero tuck position on the armrests during descents, on uneven roads, while hydrating and even when reaching into jersey pockets for nutrition
The AFS approach ensures the rider can maintain a proper aero position longer through an easy, accurate fit therefore ensuring aerodynamic efficiency and the ultimate in performance.
Aerodynamics: CFD Virtual and Actual Wind Tunnel Testing
Because the E-116 is made using the E-118 mold, it reaps all the benefits of Computer Fluid Dynamics testing- the virtual wind tunnel. These tests have given our R&D team an accurate, detailed picture of airflow behavior around the bike and rider at all wind angles, letting the designers maximize aero efficiency in every part of the bike. A number of design variants were tested and the most aerodynamically effective shapes were incorporated into the final version.
CFD: cutting-edge technology for cutting edge performance
While every aspect of the E-116 itself was tested and optimized through exhaustive computer simulation tests, Argon 18 took this process farther still. Making the most of CFD software’s almost unlimited computing power, Argon 18 completely digitized a pedaling cyclist- in this case, triathlon champion Tim O’Donnell-in order to include the rider in the design process from the outset, because the rider is by far the main source of drag. This inclusion of a virtual rider let our R&D specialists test every permutation and hypothesis, resulting in a bike that’s seriously aerodynamic in the real world.
Wind tunnel data validation: the numbers speak for themselves
In the final validation phase, the E-116 turned out to be 4% to 9% more aerodynamically efficient than the E-114, depending on yaw angle, in identical conditions….which means a faster bike split.
BB86 Bottom Bracket
The E-116 features a BB86 bottom bracket shell. This threadless system relies on press-fitted sealed cartridge bearings. With BB86, traditional threaded and external threaded are no longer necessary, reducing weight while boosting rigidity where it matters most.
Out of the box, the E-116 is equally compatible with Di2 or mechanical components. Regardless of the group you choose, all cables and wiring are internally routed for enhanced aerodynamics.
Total Integration, taken a step further
The E-116 takes integration another step forward, with intelligently-designed components specific to the E-116.
Apart from the monocoque frame, these include:
•TRP’s Advanced Braking Systems, a very powerful V-Brake system that is tucked away behind the front fork and bottom bracket, generating virtually no drag.
•The new ASP-7500 reversible seat post has been updated with a lighter, simpler & low-profile seat clamp design-exclusive to Argon 18.
