The Gallium Pro embodies the essence of what the company has meant and has been striving for since its beginnings 25 years ago. As it’s always been the case with Argon 18 bikes, the new Gallium Pro incorporates a solid grasp of traditional time-tested cycling knowledge and cutting-edge technological research and advancements. Thanks to the exceptional stiffness to weight ratio made possible by the 790g carbon frameset, response is even more immediate and handling is razor-sharp on any terrain.
Starting in 2015, the new 3D system is now press-fitted, which means less parts, less weight and less potential vibrations.
The Gallium Pro also sets a precedent for its exceptional positioning versatility. With proven, intelligently conceived AFS geometry in its six frame sizes, the new bike furthers this versatility with the ASP-6500 reversible two-way seat post (seat clamp offset -15 to -25mm), offering an extremely wide range of adjustment.
When all of these positive attributes are taken this far, that spells “race winner" or, in other words, Gallium Pro.
