Advantages of a carbon frame.

1).It is possible to make a lightweight frame.

A carbon frame is made by layering carbon fibers in the direction of stress. The carbon frame is very lightweight, which is due to its density and strong tensile strength.

Giant's carbon frame is very light, and the 2000 model is heavy.

2).Good shock absorption.

Carbon fiber is used in a variety of fields such as prosthetic legs for people with disabilities to exercise and special springs. It takes advantage of its excellent impact absorption performance to make a bicycle without a shock absorber. Elevated frames such as the Scott factory are famous.

However, the quality varies greatly between various manufacturers, and some are very hard, so this kind of frame can only be known after riding.

3).Frames of various shapes can be manufactured.

The basic molding method of carbon fiber is to lay fiber sheets on a mold, which then flow into the resin and are sintered. It can be made into frames of various shapes. Y frames such as Trek are famous.

Disadvantages of carbon frames.

1).Complex stress calculations.

The carbon fiber frame is made up of carbon fiber, which is characterized by strong tensile strength but weak shear strength, and complex stress calculations (longitudinal rigidity, transverse rigidity) are required during processing, and the carbon fiber sheets are overlapped according to the calculations. The processing technology varies from manufacturer to manufacturer, and it is very important to choose products that have experience and can be used by manufacturers.

2).It is difficult to change the size.

Since it is molded after molding, it is difficult to change the size. It is not possible to respond to orders of multiple sizes and styles.

3).Aging?

Does resin age? This is an existential subject that gradually turns white when placed in sunlight. Of course, this phenomenon is related to the manufacturer's technology. It is best not to leave it in the sun.

Use gauze or a coarse cloth to remove the rust, and then apply some mechanical oil while the body is dry. I don't know if you're talking about the body or the chain.

The so-called high-carbon steel is rusty.

1. Rust removal method with engine oil (lubricating oil):

1. Apply oil evenly to the rusty area.

2. Wait for 1-2 hours and then wipe the rusty parts repeatedly with a dry rag until the oil is completely wiped off.

3. Observe the rust cleaning status, if there is still rust that has not been cleaned up, please repeat steps 1-2, you can extend the waiting time appropriately. Repeat 2-3 times to remove any remaining rust.

2. Rust remover (bolt loosening agent) removal method:

1. Spray rust remover evenly on the rusty part.

2. Wipe the rusty parts repeatedly with a dry rag until the rust remover is all wiped off.

3. Observe the rust cleaning status, if there is still rust that has not been cleaned up, please repeat steps 1-2, you can wait for a period of time before wiping. Repeat 2-3 times to remove any remaining rust.

Yes, there are various activities such as skiing, skydiving, diving, etc., and there are also some that will take you to experience!
