The Argon 18 E-118 Tri+ S is a high-performance triathlon and time trial frame designed specifically for smaller athletes seeking an aerodynamic, stiff, and comfortable bike to maximize race-day performance. Crafted with ultra-high-modulus carbon fiber monocoque construction, the frame delivers exceptional weight savings and rigidity for efficient power transfer.

Material & Construction:
The E-118 Tri+ S features a precision carbon fiber layup focusing reinforcement at the bottom bracket and head tube for maximum torsional stiffness and steering precision. Areas like the seat stays and top tube are engineered for controlled compliance, absorbing road vibrations to reduce fatigue during long rides.

Aerodynamic Efficiency:
With aggressively shaped airfoil tubes and fully internal cable routing, the frame minimizes drag and optimizes airflow over and around the bike. Integrated rim brakes further reduce aerodynamic penalties without compromising braking performance. The frame is compatible with triathlon-specific aero bars and extensions, enabling riders to achieve an optimal, aerodynamic riding position.

Geometry and Fit:
Sized for smaller riders, the E-118 Tri+ S uses triathlon-focused geometry that promotes a forward, aggressive position designed to maximize speed while balancing comfort for endurance efforts. The frame supports smooth transitions to running by encouraging efficient muscle engagement and reducing strain.

Bottom Bracket & Drivetrain:
Equipped with a PressFit BB86 bottom bracket, the frame ensures solid crankset compatibility and efficient power transfer. This setup complements the frame’s stiffness, allowing riders to maintain high cadence and power output with minimal energy loss.

Ride Quality and Performance:
The frame offers a crisp, responsive feel with a refined balance of stiffness and vibration damping. This combination allows triathletes to ride aggressively without compromising comfort or endurance. The aerodynamic design and integrated components ensure the E-118 Tri+ S remains competitive on all triathlon courses.

Target Rider:
Ideal for smaller triathletes and time trialists seeking a race-optimized frame that delivers exceptional aerodynamic performance, power transfer, and comfort tailored to their size.
