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.

This is the best road bike I've ridden

By Steve Faulkner from GB,
May 12, 2020
I got this bike early in 2020 and was amazed at how good the ride was. From the first short ride it was clear how stable the bike was compared to other road bikes I've ridden. I've now been riding the Gallium Pro Disk for a couple of months. The transition of power through the pedals is awesome. The bottom bracket is super stiff and you feel absolutely no flex in the frame when sprinting full-gas out of the saddle. The front end is also really stable both when cornering and at high speed in cross-winds. It gives you the confidence to really throw the bike into corners without having to worry about the front wheel flapping and losing grip. The Gallium also climbs really well, again thanks in part to the super stiff frame, but also the comfort that is afforded to the rider by the optimised geometry. I've recorded some of the highest average speeds on my regular routes on the Gallium over flat and undulating terrain. This really is a fast bike! This is also the first road bike I've ridden with disk brakes and I'll never go back to rim braks! The braking power and modulation of breaking is excellent and allows you the brake harder and later than is possible with rim brakes and in the wet and rain they become even more impressive. I've had no real issues with rotor rub and haven't had to re-centre the callipers since the first ride and have logged over 2,000km on the bike since then. I can't recommend this bike enough to anyone who is looking for a genuine thoroughbred race machine.
