About Argon 18
Montreal winters force Canadian cyclists to think about bikes differently. Gervais Rioux founded Argon 18 there in 1989 and built a reputation for precision that reflects the city's engineering culture. While the rest of Canada gets overshadowed by American brands, Montreal quietly produces bikes that win at the highest level.
The 3D fitting system matters more than most buyers initially realise. Argon 18 builds geometry adjustment directly into the frame, letting you fine tune position without swapping stems or seatposts. For triathlon bikes where millimetres matter, this is genuinely useful rather than merely clever. The E-119 time trial machine carries that precision into aerodynamic obsession. The Gallium road bike applies similar thinking to more conventional racing.
British time triallists and triathletes have discovered Argon 18 because results speak louder than marketing. The bikes win at Ironman and on the World Tour without the brand spending millions on celebrity endorsements. For riders who care about engineering over image, who want bikes designed around proper fit rather than forcing fit onto standardised frames, Argon 18 offers Canadian precision at prices that undercut more famous competitors.
Argon 18 bikes currently start from £1,050 and run up to £1,050 across the marketplace.
What to look for when buying a used Argon 18
Argon 18 bikes are best for road racers and triathletes seeking precision engineering with adjustable fit.
When buying any used Argon 18, start with the basics. Check the frame for cracks, dents, or damage, especially around the head tube, bottom bracket, and dropout areas. Look at the drivetrain for wear and make sure the gears shift cleanly through the full range.
Ask the seller for service history and proof of ownership. Every Argon 18 listed on Cyclesite is automatically checked against UK stolen-bike databases, but it is always worth checking the frame number yourself too.
Typical Argon 18 pricing on the used market sits in the £2,500 to £12,000+ bracket. Anything notably outside that range is worth a closer look.

Gervais Rioux founded Argon 18 in Montreal in 1989, bringing engineering precision to a market dominated by European tradition and American marketing. The 3D adjustable fit system emerged from understanding that proper position matters more than most frame manufacturers acknowledge.
