Mountain bikes About fork type, frame type, braking system. Which one is better???

Among the 25 components of a mountain bike, such as the frame, tires, pedals, brakes, and chains, all of them are indispensable. Among them, the frame is the skeleton of the bicycle, and it carries the most weight of people and cargo. According to the working characteristics of each component, it can be roughly divided into guide system, drive system and braking system

1. Guidance system: composed of handlebar, front fork, front axle, front wheel and other components. The rider can change the direction of travel and maintain body balance by manipulating the handlebars.

2. Drive (transmission or walking) system: composed of pedals, bottom bracket, crankset, crank, chain, flywheel, rear axle, rear wheel and other components. The pedaling force of the human foot is transmitted by the pedal through the crank, sprocket, chain, flywheel, rear axle and other components, so that the bicycle continues to move forward.

3. Braking system: It is composed of brake components, and the rider can manipulate the brake at any time to slow down and stop the bicycle to ensure driving safety. In addition, for safety and aesthetics, as well as for practicality, it is also equipped with parts such as lights and brackets.

Compose. 1. Body part: including frame, fork, handlebar, saddle and fork assembly, etc., which is the main body of the bicycle.

The transmission part of the bicycle (20 photos) includes pedals, cranks, sprockets, chains, bottom brackets and flywheels, etc., which are pedaled by manpower, and the wheels are driven to rotate through the above transmission parts and drive forward. 2. Action part: that is, front and rear wheels, including front and rear axle parts, spokes, rims (rims), tires, etc.

3. Safety devices: including brakes (brakes), lights, bells, reflectors, etc. As needed, some accessories can also be added, such as stands, hangers, safety forks, fenders, air pumps, etc.

In addition, sports cars, racing cars, and mountain bikes equipped with a transmission mechanism are equipped with a transmission controller and front and rear derailleurs.

1. Spring.

It has the longest history and is the most common type of spring used in moto. The hardness of the spring, the so-called elastic coefficient, represents the ratio of force to deformation. Under the principle of not exceeding the load, the elasticity coefficient of the simple coil spring is fixed in the state of different forces, and will not be affected by the ambient temperature, and then after painting or lubrication, the stability and durability are very high.

But the only downside of the lineside springs is their weight, so the lighter, but more expensive, titanium springs have been used for the more advanced forks.

2. Air pressure. Because the air is light, using air as a spring should be very suitable for bicycles, and if you need a different hardness, you don't have to replace the spring, you just need to increase or decrease the air pressure.

However, the use of gas pressure springs must have more sophisticated technology, high-pressure gas must be completely sealed, once the air pressure is lost, it can not work at all. Therefore, in the early days, the gas pressure spring had the problem of sealing, and there was even a sudden loss of all the air pressure in use, and this kind of problem no longer occurred.

I think there are two main types: oil spring forks and air forks.

As long as it's not an air fork, there's definitely a spring and oil; Without a pure oil fork, the compression ratio simply cannot be achieved.

The top tube is divided into tapered and plain.

There are also special ones, such as the left-handers of cannondale.

There are mainly 2 types of spring forks: oil spring forks.

Spring forks, oil spring forks, oil and gas forks.

Spring forks, oil spring forks, oil and gas forks, hard forks.

1. Fork brand.

1) My favorite brand: Rock Shox. The fork brand of SRAM in the United States is characterized by being thick, durable and hard.

Common styles: dart1, dart2, nothing to say, dart2 with lock and without lock, dart3 has two types of shoulder lock and wire lock.

The advantage of the DART series is that it is sturdy and durable, and it is a good place to start with it, as it is basically resistant to all kinds of construction.

2）rst。

This brand is mostly used on entry-level mountain bikes, and it belongs to the most inexpensive and cost-effective forks.

**Low, the quality is not very guaranteed, mainly reflected in the itinerary is not accurate, some people say, buy this fork, sometimes it depends on luck.

3) Suntour (three tories).

This brand has two entry forks, XCM and XCR, and the reviews are average. The most famous of Santuo is the air fork Suntour Epicon, which can be bought within 1000 yuan, and the quality of Santuo is still ***, but the air fork is an air fork after all, or a cheap air fork, and it can't be made like a dart.

2. Zoom forks are generally used on low-end cars, and the quality is average, so it is not recommended.

3. Mountain bikes don't seem to have the best suspension, only front suspension and rear suspension, the front suspension is the front fork, and the rear suspension refers to the shock absorber on the tail fork or riser.

The main function of the rear shock is to absorb the vibrations experienced by the rear wheels.

4. Ordinary frames cannot be equipped with rear shocks, and frames designed with rear suspension systems must be purchased, and rear shocks are also divided into three types: spring, oil pressure and air pressure.

When you say ** suspension, is it a shock seatpost? It is to add a shock absorber to the seatpost, which should be a very useless thing.

As long as the shock can be mitigated from acting on the human body, the problem of cathartic force cannot be avoided.

1.I will first talk about the fork The grade of the suspension structure is from low to high, spring, oil spring, excellent glue, mud resistance, oil pressure, and air pressure.

The outer tube has magnesium alloy and aluminum alloy, steel.

Common brands are Fox Rockshox, RST, Suntour, Mazuchi, Manito, TGS, and Spu.

These are common, I won't say anything about the others, you will cry if you buy a bad brand, it will be scrapped in half a year, and there are hidden dangers! The forks are all one, all of them have no welding marks, and the bad ones are very annoying when they go back, and maybe the disc brake position is not right or something, it is possible.

Let's talk about a few common misconceptions.

1.The larger the fork calibration stroke, the better.

First of all, the calibration stroke is not equal to the actual use of the stroke; In addition, for XC, too long strokes are useless, generally between 60mm and 100mm, and 80mm is more common.

2.The more fork features, the better.

One of the things to say is locking, which is generally not used except for climbing and riding long distances, but usually forks will have this function.

3. Regarding the shock absorption form of the front fork, the common ones are springs, oil springs, and better air forks. Except for the air fork, everything else must have a spring, so the so-called hydraulic shock absorption belongs to pseudoscience, hehe. And basically (it can only be said that there is basically no absolute karma in the world) forks below 1000 can catch an oil spring, thank God.

2.I don't know.

3.It shouldn't make a difference, it's all called a softtail car anyway.

4.It's enough to change to a soft tail frame and buy a rear oil spring!

Large factory: Rockshox Manito Matsuqi Fox small factory: Sipu SR Santuo RST

zoom = garbage, the handlebars commonly used in mountain group cars back then were zoom, and they bent directly with force, but they were also cheap.

I don't know what you ask about ** shock absorption and rear shock absorption, if you don't have a budget of more than 4000, you can stay away, and ordinary cars can't be changed to rear shock absorption.

If someone sells you a softtail car, under 8000, it is definitely cheating you.

The air fork of the fox also has a spring, which is called a gas spring.

Recommend Xidesheng's mountain bike, and you have to tell me what grade of car you need, the car ** gap is very big.

I don't think it's good to choose aluminum alloy for the frame on the road surface that is not the limit of the platform, if you are an enthusiast, of course it is carbon fiber, and the fork is also OK if it is not too demanding. There are also ** high but very general materials on the market! I personally recommend using the fox is good, **a bit high.

Generally aluminum alloy now, but also divided into 6061 7075 I prefer the steel frame, but the good is not cheap, but the comfort is better than the weight of aluminum alloy carbon fiber, rigidity, and comfort are excellent, but **. Forget about fox.,Basically, there's nothing left except for the bag.,Now there's more XCR and DART3.

Aluminum alloy, most of them are aluminum alloys, and the high-end products are carbon fiber.

There is only one option. Cheap (generally under 10,000 RMB) bikes are now made of aluminum. Because the steel frame is much heavier than aluminum alloy, only a few cheap cars with a few hundred dollars and some extreme bikes still use steel frames.

Other common materials are: titanium alloy, magnesium aluminum alloy, scandium alloy, carbon fiber, don't think about these for ordinary bicycles, hehe.

Choice of bicycle frame and fork material:

1. If you often ride on city roads or flat roads, you can choose aluminum alloy, titanium alloy, carbon fiber frame and fork. (Flat roads have no requirements for frames and forks).

2. If you often ride on mountain roads or potholed rural roads, you can choose a frame and fork made of chromium-molybdenum steel and titanium alloy with higher strength.

3. If you often participate in competitions, you can choose a lighter titanium alloy and carbon fiber frame and fork.

The low price is what the Zoom Giant low-end car uses. Truth be told, a low-end fork without lockout is not as good as a hard fork.

Low price... The air fork is on the side. Only spring forks. Don't lock it up, rs dart1 we use it feels good and durable. It seems that xcr said that it will become a death fork in more than 1 year... If you want an air fork, then a god fork.

There is no such thing as the best value for money.

You can understand it this way, cost-effective, first of all, it is definitely not the biggest brand, such as fox rockshox Matsuqi.

It can only be considered Zoom Innova or even RST those.
