Shared E119 platform advantages
- Integrated aero platform: the E119 is built around a clean front end, hidden routing, integrated cockpit, integrated brakes, and race-focused tube shaping.
- Race-day storage: the Storage Optimization System, integrated deep bento, and hidden toolkit help keep nutrition, tools, and repair essentials organized without compromising the superbike look.
- Triathlon fit adjustability: adjustable armpad stack and reach help riders dial in an aero position for sprint, Olympic, 70.3, full-distance triathlon, or time trial racing.
- Disc brake control: the Argon 18 Integrated Brake System pairs clean aero integration with the consistency riders expect from modern disc-brake triathlon bikes.
- Premium cockpit contact points: 51 Speedshop Custom Extensions are shaped to hug the arms for aero positioning and use a 30-degree grip angle to support neutral wrist orientation.
