Argon18 the Canadian bicycle manufacturer launched their redesigned Gallium road bike. Argon18 Gallium Road Bike 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 from 2008 to be 20% stiffer laterally and 6% lighter.  Frame is 940g (55cm) and their exclusive Ga31 fork, custom built for this bike, weighs 356g.

• New 3D Head tube allows for variable effective head tube height for each frame size, for optimal fit and comfort.

• Exclusive Argon 18 Ga31 fork is an integral element of frame design.

• Vertical Compliance has been further refined for plush comfort at any speed.

• Weight 940 grams (Medium frame); Fork 356 grams.

• New silver spacers system at the top of the head tube have interlocking grooves that nestle into each other and form a stiff extension of the head tube, versus spacers that just rest on the fork steerer tube between the stem and the headset. Theoretically increases the stiffness in the front of the bike.
