Product Description

General Information

The Argon 18 Gallium CS 105 is more than just a taste of a professional-level road bike. This is the best price you can get for the world-class reputation of the Gallium. An economical carbon layout and Shimano 105 groupset keep the price down while maintaining great performance on the climb and sprint. If you are ready to step up your performance on the road, the Argon 18 Gallium CS Ultegra is a great start.

Like all Gallium models, the Gallium CS 105 is very light and excellent on the mountains. The frame is made of more economical carbon that gives you a discount without a sacrifice to performance. This carbon frame is UCI approved so you will be able to use it in any race you desire with no issues. The Argon 18 Gallium CS also includes a light and stiff fork to cut down on weight even further.

The Gallium is an entry-level road bike, but it still gives riders of all sizes an aggressive riding position for fast descents and aero improvement. Size-specific geometry was utilized for a well-balanced ergonomic fit for every frame. Argon 18’s Press-Fit 3D system offers three headtube heights for each size to customize fit without sacrificing rigidity. This system preserves five and 11 percent more incremental frontal rigidity vs. standard spacers when the handlebar is set at 15mm and 25mm respectively.

The Argon 18 Gallium CS 105 can do much more than climb. This versatile machine is aerodynamic and aggressive enough for a speedy descent after a tough climb. The stiffness to weight ratio is excellent, allowing you to close the gap on flat ground when it comes time to sprint. You will feel comfortable using the Argon 18 CS 105 in any stage on the road that you encounter. If you are the type of rider who likes to create a chase group, this is the bike for you.

If you are looking for a seriously fast and light entry-level road bike to get your foot in the door in the racing world, the Argon 18 Gallium CS 105 is an excellent option. With this bike, you will have an outstanding balance of weight and stiffness to fulfill all your needs from climbing to chasing and general sprinting. A carbon frame and Shimano 105 groupset top off one of the best built bikes in this price range. The Argon 18 Gallium CS 105 is here to upgrade your road performance and help you go fast.
