    There is no danger, and it may be a mistake.

    Very dangerous. For example, the master brother who set the world DH record broke his spine after the accident, and worked as a vegetative person on the bed and the tomb for two years.

    DH is downhill (down hill), DH also has a nickname for falling hill, the popular point means to jump down the mountain by bicycle, can not fall to the ground, all the way down the mountain, the world DH limit speed reached 333 km h. In this case, the slightest mistake is the end of the destruction of the car.

    The structure of the DH car

    The structure and parts of the DH car are directly related to the player's own safety. The body of the DH can be roughly divided into several parts. First of all, the frame, most of the frames of DH cars use ** suspension with a shock drum in the middle, and the frame quality is mostly pressurized aluminum alloy carbon fiber.

    The frame is heavier, and its famous brands are Tdiamondback, Cannondale, etc.

    The front fork of the frame is also very particular, which can be divided into two categories: one is the high-level suspension front branch fork, commonly known as the "high fork", and the other is the low-level shock, and the suspension front plug is famous: Rock Shox, Moto, Manitou, RST ......

    Secondly, the size of the car's crankset, transmission, etc., basically use kits, and the XTR series produced by the Japanese Shimano factory is relatively good. And because of the high speed of DH movement, most players choose the superior performance of disc brakes.

    The deceleration car is fast. First of all, you need to know what does downhill mean? DH is the abbreviation of Down Hill, which originally means downhill car, or it can be said to fall down a mountain, which means to rush down from a mountain.

    Rappelling, similar to a free-fall sport in which you can jump from a height. With good athletic skills, long enough distance, and a bit of luck, the descent speed of this exercise can reach a speed of 333 km/h. This puts forward high requirements for the frame strength and shock absorption treatment of the downhill car.

    Because there is no need for people to pedal, it is completely descended by gravity. So there is no requirement for the weight of the car. So, the disadvantages of the downhill car are also obvious, too heavy! Riding on the rider on any road other than downhill is a nightmare, slower than any kind of bike.

    The range of mountain bikes is extensive. Downhill is actually a special kind of mountain bike, generally called a soft-tailed mountain bike, and you can play ordinary downhill. And the professional downhill bike, the DH bike, is the most expensive of all mountain bikes.

    In general, the mountain bikes that we ordinary people talk about are mostly single-suspension hardtail mountain bikes ridden by the mountain horse party. This kind of car can be ridden on urban paved roads and rural dirt roads, and if you play rappelling, you will be able to die.

    Therefore, we ordinary people define the downhill car as a professional DH car or soft tail; A mountain bike is a regular XC hardtail.

    If you play downhill, it must be a soft tail or a DH car that is fast. I'm not afraid to fall. The hardtail plays downhill and falls apart in a few clicks.

    Upstairs... Can you not copy.

    Downhill is more demanding on the bike. Generally, those who play downhill have a special downhill (DH) mountain bike. That kind of bike is better than ordinary mountain bikes in terms of strength and toughness.

    Not only will it make you have a great time. And keep you safe at the same time. If it's a mountain bike in general.

    I'm not sure it won't go wrong if the downhill intensity is too high. At the same time, both novices and old birds must wear protective gear. Downhill is dangerous.

    Once something goes wrong. Protective gear is life-saving. No matter what, it can save you thousands or even w medical expenses.

    Finally, downhill is physically demanding. At the same time remind. If you are a newbie.

    Don't play too hard in terms of difficulty and intensity. After all, safety comes first.

    If you have a budget of tens of thousands, you should buy an ordinary XC mountain bike to play with It's up to you to see if it's fast or not.

    Don't buy Avert and Merida, it's all over the street, just go to the store and assemble it yourself, 4000 5000 assembly is better than the original.

    Downhill is just one genre of mountain biking.

    Generally speaking, the downhill is fast, but not because it is fast, but because it is rushing down the hill for a stronger structure and more powerful shock absorption, and it is not powerful to ride on the flat road at all.

    Now that you have determined the brand and **, there is no need to ask what model, just go directly to the store, their product line guarantees that there is only one car in the same series at the same price.

    I'm sorry to tell you that it's basically impossible to buy a Giant downhill bike in Chinese mainland, and Merida can only buy all-terrain mountain bikes like the TREM or 96 Supreme (PS: the team version costs more than 22,000). The difference between downhill bikes and ordinary mountain bikes is actually only in shock absorption and strength, and the shock absorption of the soft tail of professional downhill bikes can not be locked, riding on general roads is very forceful, and the reason why some people can exceed 150 miles when downhill also depends on free fall.

    The 4000 5000 or so interval can already go and form a car by yourself, and if it is a Merida mountain bike, you can also take a look at the Navigator or Challenger series.

    With this budget, how can you buy a downhill. I've seen rappelling in China, and people do it themselves. **58000

    1. Not at all. If this car is a genuine Giant, it is also a very entry-level recreational hardtail mountain bike, which is a general dirt road on and off the road. I can't even play XC (i.e. off-road).

    2. For real off-roading, you need an entry-level (generally priced at 3K is a watershed) XC-class hard-tail mountain bike, or an XC-class soft-tail mountain bike with a rear suspension device (i.e., rear shock). 3. Further up the high-intensity off-road, it is a trail (i.e. trail) class hardtail mountain bike or softtail mountain bike. 4. The off-road intensity is high, no matter how big the action is, and it also requires higher control skills and experience, it is an AM (that is, all-terrain) class soft-tail mountain bike, which is to go to the hills and mountains to cross the stone formation, and there are coiled knots and staggered large tree roots mixed with more than half a meter high step type jumping slope.

    5. Further up is the Enduro (i.e. all-terrain endurance) class softtail mountain bike, which is stronger than the AM-class backcountry passability, and can fly down slopes more than one meter high, but requires the rider to have stronger physical fitness and skill. Riders are also expected to wear specially designed mountain bike helmets, knee pads, elbow pads, and shin pads. 5. Finally, it is the soul of "playing mountain bikes", that is, what you call "downhill", you need to ride a DH (down hill, that is, downhill, also called falling mountain) soft-tail bike.

    This mountain bike is generally the most robust and resembles a motocross bike. Drivers must also be the most skilled, experienced, and courageous. Because riding a DH bike is all the way down from the top of the mountain, it will fly down when it encounters a drop of several meters or even more than ten meters.

    The downgrade mountain bike can't press the road, it will be very tiring legs, and it will be difficult to ride on a big slope...

    The XC-class hardtail mountain bike and its counterpart to the typical off-road terrain. Your Giant is barely okay (but it can be bumpy if you ride it slowly, and you may get your foot off the pedal when you hit a pit, lose your center of gravity and crash).

    XC-class softtail mountain bike. This off-road, with a lot of roots mixed with soft sand and pits, is difficult for an XC-class hardtail with a lot of high-end equipment, and your car will definitely not work.

    Trail-class hardtail mountain bikes. The structure is stronger than that of the XC-class hardtail, and the geometry, fork and wheel configuration are also significantly different.

    Trail-class softtail mountain bikes.

    AM-class softtail mountain bike. Riders wear full helmets and knee pads (not Nike knee pads for basketball).

    Enduro-class softtail car.

    Downgrade softtail car.

    May be a little annoying. It's still safety-oriented. Don't take this risk, it's not good for your health. If you want to play downhill, it is recommended to use a special downhill car, on the one hand, the riding experience is different, on the other hand, it is safer.

If you don't consider your actual use and capital reserves, of course, the higher the better. Generally speaking, the higher the number of shifts, the smoother the shifting, which can bring a comfortable, smooth feeling to the ride, and of course, the higher the speed.
