About Argon 18

Argon 18 was founded in Montreal, Canada in 1989 by former professional cyclist Gervais Rioux.

They are the official bike supplier to several professional teams and have been a fixture in elite triathlon for decades.

The Argon 18 range includes the Gallium road racing platform, the Nitrogen aero road bike, the Sum gravel bike, and the legendary E-119 and E-117 triathlon bikes. Their innovative 3D System allows riders to fine-tune their position with adjustable head tube geometry - a feature unique to Argon 18.
