Argon 18 Gallium Specs and Performance

Shifter Specs and Performance

The Shimano shifters that came with my Gallium provide smooth climbs and descents. It is efficient and enables me to shift gears with ease.

The bike tracks precisely and is always simple to handle, whether moving quickly or uphill when out of the saddle. A clever blend between stability and agility makes it quite enjoyable to maneuver around corners or challenging areas.

Rear Derailleur Specs and Performance

The Gallium is excellent for quickly covering ground since it has a delightfully smooth level of compliance. The Argon 18 3D System is incorporated to aid handling and riding posture optimization.

In my experience, the switch to a direct mount derailleur provides more effortless shifting. 

Cassette Chain Specs and Performance

Gallium Pro's cassette and chain

Gallium Pro’s cassette and chainring sizes, as well as the size of the cranks, stems, and bars, can all be freely chosen.

My Gallium has a rigid chassis through the head tube, bottom bracket, and chainstays, making it a beautifully smooth-handling bicycle. It has a pleasant level of compliance above this sturdy undertray, making it excellent for quickly traversing distances.


The Gallium Pro Disc isn’t the smoothest ride; minor bumps can be demanding for the rider. Vibration dampening is mid-range. Luckily, the Vittoria Corsa Control tires installed significantly increase comfort.

Installation and Setup

United Cycling has done a fine job setting up my Gallium Pro. Assembling the parts can be tricky if you are new to cycling, but seasoned riders can quickly build the bike.


The 15th Anniversary Edition of Argon 18 Gallium Pro Disc stands out with a sleek luster and optics influenced by the original models from 2005.

The Gallium still has a simple, understated look. Its minimalist design in a fantastic race bike is only a little expensive for the level of equipment.

Argon 18 Gallium Price & Value for Money

Gallium’s price varies on the customization you choose. It is still worth the purchase if you are looking for an efficient race bike.

You may choose from different Gallium configurations, ranging from an affordable Shimano 105 build (€ 5,380) to a standard DURA-ACE Di2 construction (€ 7,899, 7.21 kg in size L).

The size of the cassette and chainrings and the size of the cranks, stems, and bars are also customizable.
