What’s the general materials of the bicycle frame ?

When  we  have a ride tour,We need to tie bicycles on the car body ,There are mainly three carrying types :roof mounted bike carrier,rear bike carrier and  hitch  mounted bike carrier,The better choice of the bicycle frame influence the maintain of the car directly.

1)The Aluminum frame 

The bike carrier made of the aluminum material is light and high strong rigidity,During the specilized processing of the bike carrier with only 1kg weight.

The aluminum pipes tend to be large diameter ,In order to improve the most intense  strong rigidity .The seat tube and fork is used to absorb the strong impact of the carbon fiber and the limelight.

2)The chrome molybdenum steel frame　 

The good twist and tensile properties,When welding high temperature does not affect the material and the lower price .However,The heavy weight ,Easily  oxidized.

3)The  carbon fiber frame:

The advantages are light and easy observe the impact of the floor , such as the quick  reverse force,Carbon fiber grade, tonnage of more high elasticity is higher, the price is expensive.There are several manufacturing methods, such as sticking to the mold, overlapping carbon fiber, heat treatment, solidification, molding, etc.

4)Titanium frame

The specific gravity of titanium is 55% lighter than steel, and it is not easy to oxidize. In order to improve the tensile strength, there are mixed aluminum, vanadium and other titanium alloy. Welding to be carried out in the vacuum, such as complex processing, expensive frame.
