What alloy is the bicycle frame and bicycle stand made of

The bike can be changed for anything, but there is no frame change.

It is generally believed that the frame is the soul of a car, so there are many small things to change, and there are fewer shelves.

You don't necessarily have to buy a Merida frame. Because the specifications of sports bikes are universal, you can definitely choose a rack that you like best.

In addition: for the consideration of angle, frame design, etc., you should be prepared to change the complete set of control lines and outer line pipes; Psychological preparation for changing stems and front transmissions; And consider the inner diameter of the frame riser. Generally yes, but there are also more than 30.

Of course it's good to change, about 300, right? I do not know.

I really want to change to a better giant ATX7 online**540

It can be dealt with, the saddle is moved forward (if the seat tube is turned 180 degrees, it will move forward more), and the saddle is further forward to ride the more effortless (according to the triathlon principle) to put down, if it is still large, replace the stem (the movement that connects the crossbar and the fork of the frame) with a short, cheap one. This saves money and trouble.

Warrior Pro this level of car is recommended to deal with, hehe.

Yes, but you'll have to think about whether it's worth it or not!

The bike stand is made of aluminum alloy.

Aluminium is a material with low elasticity and rigidity, and its specific gravity is light but not hard enough, so it is alloyed and heat-treated for strength. Many aluminum frames are made of 6061T6[I] material, and the T6 logo indicates that it has been heat-treated. Without heat treatment, the strength can only reach the level of 1 2, or 1 5.

Generally, small factories cannot afford to purchase heat treatment equipment. In addition, there are usually 7005 and 7075 aluminum alloy materials used in the production of bicycle racks, and the strength of 7005 alloy is not as strong as that of 7075 alloy.

Aluminum itself is a metal that is susceptible to corrosion, and the more you ride a bicycle of this material, the higher the number of times stress occurs[ii] occurs, and the strength changes significantly. In recent years, in order to reduce weight, many frames have been made of thin materials (which have reached the limit of thinness), and their service life will be greatly affected.

The structure of the bicycle: there are front wheels, spokes, hubs, forks, front brakes, steel cables, brakes and shift handles, handlebars, vertical rods, frames, front shifters, seat posts, saddles, rear brakes, shelves, flywheels, reflectors, rear wheels, rear shifts, foot braces, valves, rear wheels, chains, wheels, pedals, and cranks.

The principle of the bicycle is the same as that of the original gyro. Bicycle motion mechanics, bicycle movement is a semi-mechanized sport. People should master certain mechanical principles and mechanical knowledge, effectively use the transmission speed ratio, reasonably grasp the exercise intensity, and skillfully save physical energy consumption, so as to achieve efficient exercise with abundant physical strength.

What is a Bike Rack? Literally, a bike rack is a device that attaches a bicycle to a vehicle and carries it. Bike racks are a must-have for the "4+2" lifestyle.

The so-called "4+2" lifestyle is a combination of 4-wheeled and 2-wheeled outdoor leisure sports. On weekends or holidays, you can meet up with three or two friends, or drive with your family to a scenic and fresh place, and then ride a bike all the way to relax completely. This outdoor recreation is more mobile and flexible than simply driving a road trip, and you get in touch with every grass and tree in nature.

It's healthier and greener than pure outdoor self-driving. It can relax and exercise at the same time. For cyclists who love the outdoors, it is even possible to start a whole new cycling journey.

The 4+2" casual outdoor lifestyle is loved by cyclists all over the world, and more and more Chinese riders also like this lifestyle, so many owners who like outdoor leisure sports want to install bicycle racks on their cars.

Types of bike racksAccording to the different positions or ways of stationing the bike, bicycle racks are generally divided into three categories.

An overhead bike rack, also known as a roof bike rack, secures a bicycle to the roof of your vehicle. It has the advantage of being able to travel fast when riding a bicycle, is professional, safe and stable, and is loved by cycling clubs and professional athletes. The disadvantage is that after the bicycle is fixed on the roof, the height increases significantly, and the passability will be affected to a certain extent.

The most stable and safest elevated bike racks in the world are all designed with double arms, such as the bicycle rack in Germany and the Eno bike rack in Japan.

The rear frame is fixed at the rear tailgate and is connected with the sheet metal gap of the rear tailgate through a metal hook, which generally does not affect the opening of the rear tailgate. The advantage is that it is more convenient to pick and place the bike compared to an elevated bike rack. The disadvantage is that the metal hook that plays a fixed role will more or less affect the amount of food in the body.

Sometimes the bicycle hangs empty, which may block the license plate number.

Ball bike racks are also known as ball rear towbar bike racks. Many vehicles can be fitted with a 50mm diameter trailer ball in the tail, which is the European standard for trailer balls. Trailer balls can be used not only for RVs, motorcycles, or other equipment, but also for carrying bike racks.

It overcomes the disadvantages of both elevated bike racks and backpack bike racks. It is currently the most stylish bike rack on the world market. Because of the ** high, it is usually installed on high-end SUVs.

The most professional trailer ball bike racks on the market are also made in Germany, that is, the German Strada and Atlas, which have entered the domestic market.

The aluminum alloy frame has the advantages of light weight, good elasticity and good resistance to moisture oxidation. It is currently the mainstream material of bicycle racks. Disadvantages: The cost is higher than that of high-carbon steel, and the strength is not as good as that of high-carbon steel.

The high-carbon steel frame has the advantages of high strength and low strength. Due to the large weight and gradual replacement by aluminum alloy, only the lower end of the bike will currently use a high-carbon steel frame. Disadvantages: Heavy weight, easy to rust in humid environments.

Related Notes:

Normal riding use does not require any technology, but in the maintenance of the bicycle, the most important and basic one, before riding, the condition of the bicycle to check, is very important, but also often forgotten, so before riding, remember to do the following checks:

Check your riding position: If you're not riding a bike that you don't own, remember to adjust the saddle to the right height before riding.

Check the tightness of the screws in each part: check whether the quick release of the front and rear wheels and seat cushion rod is locked, check whether the handlebar has been fixed, and whether other screws are loose.

Check the tires: check whether the tire pressure is sufficient, if it is insufficient, hit it to the appropriate pressure, check whether the tire wall is cracked, whether the cut tread is too shallow, and if necessary, replace the outer tire.

Introduction: The frame is the soul of a bicycle, a very important component, a suitable and high-quality bicycle rack, can directly enhance the riding feeling, improve the cost performance of the bicycle, so when choosing a frame, what should be paid attention to?

The size of the frame

The first key to the frame is its size, and a frame must match the height of a rider, arm length, etc., in order to be really suitable.

Frames that are too small tend to make the riser sit post too long in order to adjust to the right height, putting the strength of these parts at greater risk, as the longer the exposure leads to the longer the length. Lever effect, the seat bar is easy to break and bend under the action of the long bar bar when falling, and even pry the frame, and the riser that is too long may also break when it is bumpy, and these parts that are too long such as "riser" are easy to cause the weight to rise and the steel to decrease, and problems similar to the sitting bar will also occur, and the riser is too long to cause the center of gravity to be excessively placed in front of the front axle, and it is easy to have the danger of turning forward when going downhill.

Too large a frame will also produce some negative problems, such as the riser is too short off-road vehicle will lead to easy tilting when climbing the angle slope, in the 580mm short crossbar, the front wheel action is too flexible, and not easy to control, the seat bar is too short and the overall is not beautiful, and especially the off-road vehicle, the center of gravity can not be more effectively adjusted before and after the height of the hilly environment when the height changes greatly.

The type of frame is selected

Another important point in choosing a frame is to use different types in an inaccessible environment.

For example, the highway or mountain frame used in the climbing environment has high requirements for the rigidity and weight of the frame, so this type of frame must have round and strong risers and inclined pipes, the bottom bracket must be hard, and the weight must be relatively light.

Frames for flat floors require better aerodynamics, such as flat teardrop-shaped inclined pipes and risers, as long as the weight of the frame is not too heavy.

The frame used for travel also needs to take into account the requirements of the frame for weight bearing and comfort, so the frame is not suitable for considering too light, the frame must be able to be installed for the rear shelf of the load, the most commonly used on the market is the aluminum alloy frame, because the metal fatigue resistance and elasticity are relatively better.

As the skeleton of the whole bicycle, the bicycle rolls wide, which determines and affects the correctness and comfort of the riding posture to the greatest extent.

The frame size of the bicycle and the comparison table with the height are as follows:

At present, the main materials that can make bicycle frames are as follows: steel, aluminum alloy, titanium alloy, magnesium alloy, scandium alloy, carbon fiber, etc., the main frames that appear in the general market are steel, aluminum alloy, Luyu titanium and bright gold, carbon fiber. Scandium alloys and magnesium alloys are recent emerging materials and are relatively rare.
