Every second. Every watt. Every advantage. That is Argon 18’s stated design brief for the Argon 18 E-119 Tri+ Red AXS Bike, and the execution backs it up. Built by the Montreal-based brand around their Pro Level Layup carbon, the E-119 Tri+ is engineered as a complete race system: frame and rider, cockpit and storage, brakes and aerodynamics, all treated as one integrated structure rather than a sum of components. The result is a bike that earns its place among the fastest triathlon platforms available.

The aerodynamic breakthrough on the E-119 Tri+ is the integrated brake system. Argon 18 built the disc calipers directly into the frame — an industry first — eliminating the protruding caliper bodies that generate drag on conventional disc brake tri bikes. This system-wide integration extends to an aero-optimized cockpit, a deep bento box built into the front end, and a hidden toolkit accessible through the bottom bracket area. The combined result of these frame optimizations and system integrations is a claimed 10-watt advantage over the previous-generation E-119 — a meaningful figure when it compounds over a 112-mile bike leg.
The cockpit is the Argon 18 Oneness System — an integrated unit combining basebar and stem in a single structure with precise adjustability. The Oneness System delivers high stiffness, leading-edge aerodynamics, and travel-friendly assembly: the cockpit can be broken down and reassembled quickly without requiring a mechanic. Aerobar extensions are 51 Speedshop custom units. The Argon Fit System ensures that geometry stays consistent across all five sizes — the 78-degree seat tube angle, 72-degree head tube angle, and 413mm chainstays are constant from XS to XL. Stack range is adjustable from 573 to 663mm on an XS, with reach running 414 to 501mm, reflecting the Oneness System’s significant positional range within each frame size.
The SRAM Red AXS E1 drivetrain runs through every contact point — derailleur, crankset, calipers, and chain — with…
