Essential mountain bike purchasing knowledge for beginners

 　　As a bicycle for mountain biking enthusiasts, mountain bikes are different from ordinary bicycles in workmanship and materials. In order to adapt to mountainous areas, the requirements for the bike are relatively high. So what details should you pay attention to? Let’s take a look below.

　　Frame: The important components of mountain bikes are divided into hard frame and soft frame (rear shock absorber frame) according to the structure. The materials are generally titanium alloy, carbon fiber, molten manganese steel, aluminum alloy, magnesium alloy, etc.

　　Titanium alloy is lighter in texture and softer, but the rear frame is softer when climbing and the price is higher.；

　　The carbon fiber frame has a hard texture and is very conducive to climbing. However, because of this, if it encounters a violent impact, the frame will crack or even break. It is very good, but it is a bit heavy.；

　　Aluminum alloy is light in weight and low in cost, but its disadvantage is that the rear frame collapses when going down a bumpy slope and has a short service life.

　　Front fork: Mountain cross-country bicycles are generally equipped with high-performance front suspension systems. The choice of front suspension forks is also very important. Its quality determines the speed and safety of the rider. The front fork has several processes that rely on air pressure, hydraulic oil, glue sticks, and springs to achieve shock absorption. The size of the stroke (referring to the distance the shock absorber or suspension fork moves due to shock absorption) is generally 40 to 120 mm, which can be selected according to different needs, so that the mountain bike can pass safely no matter what kind of complex ground conditions it is.

　　tire: Thick tires and strong grip are also the main features of mountain cross-country bikes. The material of the tire, the arrangement, shape and depth of the tread pattern and tire grains determine the performance of the tire. Different tires should be selected on different road surfaces.

　　Transmission system: The hand derailleur (handle set), front derailleur (front derailleur), and rear derailleur (rear derailleur) are the main components of the transmission system. Their selection and debugging determine the speed of the transmission. The combination of different brands or large differences between old and new may cause inaccurate or slow shifting, or even failure to operate.

　　Transmission system: The lubrication of the front, rear and center axles must be good. Its lubrication quality is directly related to the rider's riding speed. The ratio of the number of teeth on the chainring of a mountain bike to the number of teeth on the flywheel is called the transmission ratio. A high transmission ratio means a rider can climb hills powerfully and easily.

　　Braking system: To ensure safety, V brakes and disc brakes are more commonly used now. The advantages of V brakes are that they are light, feel good, and are easy to maintain. The disadvantages are that they have requirements on the use environment. In rainy days, the brakes are basically zero and the rims will be damaged. ； Disc brakes are divided into three types: cable disc brakes, oil disc brakes, and oil disc brakes. Its advantages are that it does not damage the rim and the brakes are flexible. Its disadvantages are that it is heavy and feels hard.

　　helmet: Made of high-strength plastic and plastic foam, with heat dissipation holes. If you accidentally fall while riding, you can protect your head from serious injuries. Cyclists should choose a helmet that is lightweight, has good wind deflection and breathability.

　　Cycling clothing: Tight fit and made of special material. It must have good perspiration, breathability, and warmth retention properties, reduce wind resistance, and have good visual effects to facilitate passersby to avoid the rider. The padding of cycling pants can reduce the friction between the buttocks and the saddle.

　　Cycling shoes: There is a small recessed groove in the sole, which works with the lock on the pedal to lock the rider's feet with the bike and prevent them from detaching when riding, making it easier to use force.

　　Gloves: It mainly plays the role of anti-slip, not only reducing the wear and tear on the rider's hands when holding the handlebar, but also providing protection for the rider's hands when he falls.

　　Windshield: Although they are said to be windshields, they are actually not only used to prevent wind and light, but also block flying insects, sand, gravel, branches and other things that may affect the rider's vision.
