In 2005, the Gallium Pro introduced a new way of thinking about pro-level carbon frames. Argon 18 were convinced that one frame could be light enough for World Tour mountain stages, stiff enough for bunch sprints, and comfortable enough for epic group rides. They’ve proven themselves right time and time again – five times, in fact, from the first Gallium right up to today’s 15th Anniversary Edition. But they’re not willing to stop there – Argon 18's racing pedigree doesn’t let them rest easy.

Celebrate the past by moving forward! 2020 marks the 15th anniversary of the Gallium line. To commemorate this anniversary, Argon 18 looks to the future and launch a limited edition of a new Gallium Pro disc. The new Gallium Pro Disc uses graphic elements from the very first Gallium, such as Gervais Rioux’s signature and the brand’s 2005 logo. But this artwork is also the result of their learnings from custom paint jobs done for their pro athletes’ bikes. It was important for Argon 18 to transfer these learnings on to bikes from their regular line-up
