Frame material from the earliest chrome molybdenum steel, aluminum alloy, and then evolved is the use of composite materials such as carbon fiber, and other scandium alloy, magnesium alloy, titanium alloy, etc., are constantly developing new materials formula, pipe fittings and structural design ability and innovative processing technology, in order to let the frame lighter, stronger and more comfortable and more streamline and beautiful. Density is one of the key factor of the frame weight, the lower density is, the frame can do the more light, the density of chrome molybdenum steel was 7.9, aluminium alloy 2.6 2.9, 4.5, titanium titanium alloy 4.3-5.1, carbon fiber composites, 1.6 1.7 mg alloy, thus the highest density of chrome molybdenum steel, carbon fiber composites. However frame in addition to the weight, but also the tensile strength and modulus of elasticity, etc., so although low density, but strength is not enough.
Can make material of bicycle frame at present basically has the following kinds: steel, aluminum alloy, titanium alloy, magnesium alloy, scandium alloy, carbon fiber, and so on, the general frame that appeared on the market are mainly steel, aluminum alloy, titanium alloy, carbon fiber. Scandium alloy and magnesium alloy is a new kind of material, recently are relatively rare.
The material frame of Giant New Energy Tec Co.,Ltd is carbon fiber.which advantages lie :
1.Front derailleur hanger:SHIMANO FD-970-E,SRAM X0 or X9
2.Monocoque construction, ergonomics design Internal cable routing of derailleur Designed to provide superior stiffness
3.Stringent production and detection
If you want to buy the frame , Giant New Energy Tec Co.,Ltd is a good choice for you.
