This newly redesigned model is focused on delivering race-day optimization, allowing athletes to shatter personal bests while maintaining comfort and control.

Key Features:

Race-Ready Optimization

The E117 offers everything a competitive triathlete needs, from aerodynamics to advanced components. Its design is drawn directly from Argon 18's pro-level bikes, making it a value-packed performance machine ready to hit the podium. The bike is engineered for maximum efficiency, ensuring that every rider can focus on achieving their best performance.

Triathlon and TT Geometry

The E117 is designed with triathlon and time trial geometry, optimizing aerodynamics and putting the rider in a more forward, aggressive position. This helps riders maintain an aero stance over long distances, conserving energy and cutting through the wind.

Argon 18 Integrated Brake System

The bike is equipped with the Argon 18 Integrated Brake System, seamlessly merging aerodynamic efficiency with braking power. Integrated directly into the frame, these brakes help reduce drag while providing excellent control and stopping power.

Scope R5 Wheelset

The Scope R5 wheelset is built for speed and stability. With a 57mm rim depth and lightweight carbon construction, these wheels are designed to balance aerodynamic performance with responsiveness, providing a stiff, fast ride that handles crosswinds effortlessly.

51 Speedshop Custom Extensions

For additional aero gains, the bike features 51 Speedshop custom extensions, with an airfoil shape that hugs the arms. These extensions include a 30-degree grip angle, offering a neutral wrist orientation for maximum comfort and upper body stability during long rides.
