Description

Destined for Glory

In 2005, the Gallium Pro introduced a new way of thinking about pro-level carbon frames. We 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. We’ve proven ourselves right time and time again – five times, in fact, from the first Gallium right up to today’s Pro Disc edition. But we’re not willing to stop there – our racing pedigree doesn’t let us rest easy. Worthy heir of a multiple stage winner in the Tour de France, the Gallium Pro Disc is ready to take you to the podium.

Ideal for

A purebred racer, the Gallium Pro Disc offers a blend of stiffness and comfort that's quick off the mark, sharp on the turns and precise in the bunch.

Passion and perfection

By Steven Lecluyse from BE, West Flanders
Jun 24, 2020
As a passionate recreational triathlete I already owned a E-117 before I bought my first Argon 18 race bike at Lievens Bike Repair in Kortrijk, Belgium. I simply love cycling. In my best years I ride 20K kilometers from spring to winter. Expectations were high, but even after the first short ride, I immediately knew and felt they were fully met. This superb Gallium Pro 15th Anniversary Edition is a true showpiece of advanced cycling technology. In this super-light beautiful bike, speed, sharpness and performance merge to unparalleled perfection, and this unseen combination results in an experience that achieves unfeasible perfection. I love this bike!
