Gallium Pro Disc 15th Anniversary
Destined for glory: designed for the pro peloton, the Gallium Pro Disc offers premium-level performance with classic road race geometry and handling. The original thoroughbred, now with the confidence and power of disc brakes and limited-edition 15th Anniversary artwork.
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. A multiple Tour de France stage winner, the Gallium Pro Disc is ready to take you to the podium.
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.
