The flagship Argon 18 E119 features new looks and new high-performance builds for 2025 including a Notio aerometer. Notio allows riders to measure, benchmark and analyze aero performance by calculating CdA and on-bike performance in real-time so you can ride further and faster.

EVERY SECOND. EVERY WATT. EVERY ADVANTAGE.

Obviously, as the name says, the Argon 18 E-119 Tri+ Disc sports disc brakes but that’s just the beginning. In an industry first, we’ve integrated the brake calipers into the frame, for an aero advantage. Integration throughout the design also means a hidden toolkit in the BB, an integrated bento box and a fully re-designed cockpit. That this bike is aero goes without saying but our focus was on full-system aero integration: bike and rider, plus all carry-ons. The Argon 18 E-119 Tri+ Disc offers up to a 10W advantage over the previous-generation Argon 18 E-119, considering frame optimization, system integration, and compatibility with advanced aero components, such as wheelsets. When optimal rider position is factored in, using new fit range capabilities, it can add an additional advantage.
