Bike Racks Light Weight, Strength Enough, Good Rigidity

- Oct 25, 2017-

Bicycle relative to the car is concerned, is the product extension and supplement. When we were stationed in an outdoor trip, a bike accompanied by a caravan would give us more fun. Especially with the family wandering in the beautiful scenery, see the envy of others eyes, think about the United States.

Driving a car to travel, carrying the task of the bike, naturally to the bike frame. So, how to choose a suitable car bike frame it?Lee believes that the choice of car bike frame need to consider the following aspects:

1, according to the type of choice of Bike Racks type

RV bike frame, sub-front device and rear device, different from the car installed in the roof. Among them, the self-propelled car can only choose after the bracket; trailer car, divided into two kinds of equipment, one mounted in front of the A-beam on the bike frame, the other is installed to the rear of the bike frame.

2, determine the number of loading bicycles

RV bike frame can usually accommodate two bicycles, through the purchase of accessories alone, can be extended to 3-4 bicycles. But for security reasons,Bike Racks the general installation of two bike frame is enough to use.

3, according to the installation location to determine the specific model

Self-propelled car

Self-propelled car can only be installed to the back, it is noteworthy that the installation position behind the body will be interfered with other equipment. Usually for safety reasons, the bike frame are installed to the rear side of the middle position, if the rear side of the door or ladder, then you can only choose the right side of the installation of the bike frame, if the back without doors and no ladder, then consider Whether there is a window on the back, if there is no window, you can choose to install a long bike frame.

Once the frame will be compared to warrior knife, knife is the life of warriors, and the frame is the soul of the bike! Therefore, the understanding of the car into the bike entry and purchase of the first chapter. The ideal frame emphasizes the light weight, strength enough, good rigidity,Bike Racks good processing quality and suitable for the rider's geometric angle design, we can see a lot of knowledge of the frame!

Do you want to buy a car? Do you know how to pick your own frame? In addition to their own needs and uses according to their own choice for the car frame, the choice of different materials will affect the weight of the frame, rigidity, strength, riding experience, appearance and price. In recent years, very popular carbon fiber car, many people are ignorant of the popular and spend big money to buy carbon car, but stressed that the expensive fiber is really the best, the most suitable frame? In order to break the myth of the material,Bike Racks we must first understand the characteristics of various frame materials and their advantages and disadvantages of comparison.

The frame material from the earliest chrome molybdenum steel, evolved to aluminum alloy, and then the use of composite materials such as carbon fiber, there are other scandium alloy, magnesium alloy, titanium alloy, the industry continue to develop new material formula to enhance the pipe and structural design capabilities And innovative processing technology, just to make the frame lighter, stronger, more comfortable and more streamlined and beautiful. Density is one of the key factors determining the weight of the frame,Bike Racks the lower the density, the lighter the frame can be made, the density of the chrome molybdenum steel is 7.9, the aluminum alloy is 2.6-2.9, the titanium 4.5, the titanium alloy 4.3-5.1, Material 1.6, magnesium alloy 1.7, which can be seen chrome molybdenum steel the highest density, the lowest carbon fiber composite. However, in addition to the weight of the frame, but also consider the tensile strength, elasticity coefficient, so although the density is low, but the intensity is not enough not.

In general, the rigidity of the frame is determined by the elastic modulus of the material, the elastic modulus of the steel is 30, the aluminum is 10-11 and the titanium 15-16.5. Therefore, when the diameter and wall thickness are the same, the rigidity of the aluminum frame is only steel frame One-third of the rigidity of the titanium frame is only one-half the steel frame. Frame strength is determined by the strength of the material,Bike Racks the strength of the reduction and the quality of the frame pipe, heat treatment process and alloy composition has a great relationship. Aluminum precipitation point only 11-59, titanium 40-120, steel 46-162, compared to aluminum is more fragile and vulnerable. In the actual design, each frame of the pipe diameter will determine the size of the frame stiffness, strength and weight, pipe wall thickness will also affect the frame strength and weight. Some of the most suitable design of the frame in some places emphasize rigid, in some places to strength, in some places to shock, it must be in different functional demands of the site with the appropriate material, and the combination of different materials technology is also a major test.

Steel is the longest used in the bike frame material, the main advantages include long ride ride rigidity, pipe elasticity (shock), pipe joints and more processing and easy to weld and do not need heat treatment, so the cost and The price is relatively low. The disadvantage is the weight is too heavy, improper maintenance easy to rust, pipe shape is not easy and metal fatigue problems. However,Bike Racks many of today's alloy steel has been in the rigid, elastic coefficient, transmission, stability, get a good effect, the only fly in the oder is still heavier weight. Steel molybdenum steel in the most common, high strength and easy to pump processing. Molybdenum can improve the strength of steel to prevent brittle; chromium can make steel corrosion, rust and prevent high temperature oxidation. Many handmade steel tube carcassers most recommend is its excellent sense of road and suitable for long-distance riding the comfort of the advantages, as the steel gourd said: "steel forever, a perpetuating!" Suitable for use in BMX Car, long distance wagon and truck.
