The Gallium Pro Disc maintains what we loved about the original bike, while adding disc brakes and dropping a bit of weight. I tested this bike shortly after riding the Cervélo S3 Disc, and the bikes couldn’t have been more different.
The Cervélo was an aero road bike, and while it was an incredibly fast bike with razor-sharp handling, it was not always the most comfortable bike unless you found yourself on well-paved road surfaces.

Riding this bike right before made me more aware of just what a perfect all-rounder the Gallium Pro Disc is. The bike offers pro-level performance and responsiveness, no matter if you were tackling a demanding climb or merely training around Regents Park in London.
In many ways, it’s the perfect bike for those who race but want to be able to take the same bike out on their weekend club ride.
When Argon 18 was redesigning the frameset for disc brakes, it increased the tyre clearance to 30mm. There’s a 27.2mm seatpost to provide more comfort, as the narrower diameter seatpost can deflect more.
There’s a chainsuck protector on the chainstay, flat mount disc mounts and a BB86 press-fit bottom bracket.
For those who have ridden the original Gallium Pro, you will not notice much change in the geometry, and the same sturdiness in its build is evident, particularly when it comes to tackling hills.
The handling surprised me on this bike, I expected it to be quite twitchy, but Argon 18 has opted for a relatively slack headtube angle, which allows the whole bike to move with you, creating a very smooth ride.

The Gallium Pro Disc uses thru-axles, but rather than the more conventional systems seen on most other road bikes, Argon 18 has adopted the unique Naild thru-axle.
It features a safety device that prevents the lever accidentally opening. You have to depress the red tab to release the lever.
On a medium frame, the brand has put 415mm chainstays, the minimum recommended by Shimano to avoid the potential for chainline issues that can occur with the wider 142mm rear axle needed to accommodate the disc brake.
Finally, the same 3D System has been used in the headtube, as the original bike, for easy height adjustment, with three head tube heights available on each frame size.
'True innovation begins where others settle for status quo. Argon 18 keeps pushing forward. Always. Cycling is our passion, and Argon 18 makes bikes for people who share our love of riding,' said Gervais Rioux, Argon 18 CEO and Founder.
'That focus and commitment has taken our brand to a stronger place in the market.'
Overall the Argon 18 Gallium Pro Disc is a fantastic all-rounder that will help you shave a few seconds off your Strava PBs.
