3K Vertical Tube

Grade carbon fiber to make the frame. Despite these practical problems, but the carbon fiber frame, or have other advantages that are not material and can Manufacturing is about 8, 9 kg lightweight bike, this lightweight carbon fiber bike, Tang slope, best reflecting their advantages, smooth and refreshing Gordon slope.

As some light aluminum frame, Gordon has a backward slope to feel the power of pull.
Carbon fiber is the carbon fiber with resin solidification things. Very light, but it is a directional material (tensile strength but easily broken), so a
The overlapping layers of thin material way to solve shortcomings.
