Argon18 the Canadian bicycle manufacturer launched their redesigned Gallium road bike. Argon18 Gallium Road Frame has a couple of unique features that set them away from each other, including an adjustable head tube height that extends the frame height without losing any rigidity like you can with standard spacers. The Gallium is their top of the line road bike.  It is available in six sizes, which is a lot for a Monocoque carbon frame, ranging from 43 to 60/62 (Sizes: XXS, XS, S, M, L, and XL).  The frame has been redesigned to be 20% stiffer laterally and 6% lighter.  Frame is 940g (55cm) and their exclusive Ga31 fork, custom built for this bike, weighs 356g.

3D Headtube is a structural extension of the Headtube. It keeps the headset bearings close to the stem, maximizing rigidity and steering accuracy even when the rider chooses an upright position. With its stiffness intact, the stem-bar combination favors hard accelerations. Three positions are available: 0mm, 10mm and 20mm.

HDS; the Horizontal Dual System is a design that varies the shape and size of the various frame sections according to the stresses experienced by each. Power transfer is remarkably efficient, response is immediate.

Internal S3; the S3 principle, applied internally. Reinforcements inside the frame vary according to frame size, putting extra material only where necessary, reducing needless weight while improving stiffness for a complete power transfer.

Easy positioning, accurate trajectories, and AFS road geometry: the Argon 18 Fit System is based on years of knowledge about the geometries required to make a bike most efficient and enjoyable to ride. This is why Argon 18 bikes are more comfortable, maximizing the rider potential.
