Argon 18 Road, Gravel, and Triathlon Bikes For Sale

Argon 18 has been building bikes in Montreal since 1989, founded by Gervais Rioux, a former Canadian road racer. The 3D headset system, which adjusts head tube height without stacking spacers, is the kind of detail that comes from someone who has actually raced.

The current road lineup centres on the Sum and Sum Pro — a platform that merged the old Gallium climbing bike and the Nitrogen aero bike into a single frame. In 2025 the Nitrogen Pro returned as a standalone aero race bike, claiming 24 watts over the Sum Pro at 45km/h. The Krypton and Krypton Pro cover all-road and gravel, and the E117 and E119 handle the triathlon side.
