How to choose a bicycle tooth plate that suits you?

Choosing a bicycle tooth plate that suits you can be considered from the following aspects:

Cycling needs and styles:

Daily commuting:

If it is mainly used for commuting on flat roads in the city, and the speed requirement is not high, then you can choose ordinary dental discs with moderate teeth. For example, the common commuter tooth plates of road bicycles are mostly 50-34T (50 teeth on the front big tooth plate and 34 teeth on the back small tooth plate) or similar configuration, which can meet the general riding speed requirements and will not be too laborious when starting and accelerating.

Long-distance riding: Long-distance riding needs to consider labor saving and comfort, and the number of teeth on the tooth plate should not be too large. The smaller number of teeth on the tooth plate can make the rider tread more easily during long-term riding and reduce fatigue. For example, for some bicycles specially designed for long-distance riding, the maximum number of teeth on the tooth plate may be about 48, and the number of teeth on the rear flywheel is smaller to ensure a more relaxed riding experience under different road conditions.

Mountain riding:

For mountain cross-country riding, the tooth plate needs good strength and adaptability. Usually, a tooth plate with a wide range of teeth is selected, so as to have suitable gear selection under different road conditions such as climbing, downhill and flat road. For example, there are 42-32-22T tooth combinations of common mountain bike tooth plates, and this multi-piece tooth plate can provide more speed-changing options and adapt to various complicated mountain road conditions.

If high-intensity downhill or extreme riding is often carried out, it is necessary to choose a durable and impact-resistant tooth plate, which is more reliable in material and structure to cope with the impact and vibration caused by complex terrain.

Competitive competition:

Road cycling competition requires extremely high speed, so it is necessary to choose a large number of teeth to pursue higher speed. In general, the maximum number of teeth of the professional road racing wheel will reach 53 or 54, and with a smaller rear flywheel, a higher transmission ratio can be achieved, and faster speed can be obtained on flat roads and downhill sections.

Mountain bike competition needs to choose the tooth plate according to different competition types and track characteristics. For example, XC (cross-country) competition needs to take into account the performance of climbing and downhill, and the choice of dental disc should find a balance between lightweight and strength; The DH (downhill) competition pays more attention to the strength and impact resistance of the tooth plate, and you can choose a stronger tooth plate with fewer teeth.

Bicycle type:

Road bike: Road bike pursues speed and light weight, and the design of tooth plate is usually simple to reduce wind resistance and weight. The materials of road bike tooth plates are mostly aluminum alloy or carbon fiber, and aluminum alloy tooth plates are relatively low in price, moderate in weight and good in durability; Carbon fiber dentures are lighter and stronger, but they are expensive.

Mountain bike: Mountain bike tooth plate needs to adapt to complex terrain and harsh riding environment, so the structure is relatively more complicated and the strength requirements are higher. In addition to the common aluminum alloy materials, some high-end mountain bike tooth plates will use special materials such as titanium alloy to improve performance and durability.

Folding bicycle: Because folding bicycle needs to be easy to fold and carry, the tooth plate is usually designed to be smaller and the number of teeth is relatively small. At the same time, in order to ensure the smaller volume after folding, the structure of the dental tray may adopt some special designs, such as folding cranks.

Parameters of the dental disc:

Number of teeth:

The more teeth there are in the big tooth plate, the faster the speed of the wheel is, the higher the speed is, but the corresponding pedaling force needs to be greater; The fewer teeth there are in the small tooth plate, the easier it is to step on it, but the speed will be relatively slow. Generally speaking, there are more than 50 teeth in the big tooth plate of road bike and about 42 teeth in the big tooth plate of mountain bike, but the specific choice needs to be determined according to personal physical strength and riding needs.

Also consider the combination of the number of teeth in the dental tray, such as the combination of two-piece or three-piece dental tray. Double-piece tooth plate is usually suitable for road bicycles and some mountain bicycles with low requirements for speed change, which can meet the needs of different road conditions to a certain extent; Three-piece tooth plate is more suitable for mountain riding in complex terrain, providing more speed-changing options.

Axis type:

Square hole shaft is a traditional type of shaft, with low cost and easy installation and replacement, but its rigidity and sealing are relatively poor, and it is easily eroded by dust and water. At present, it is still widely used on some low-end bicycles.

The connection strength and rigidity of the spline shaft is higher than that of the hole shaft, which can better transmit the pedaling force, and has good sealing performance and is not easily affected by the external environment. However, the price of spline shaft is relatively high, and it needs to be used in conjunction with the supporting tooth plate and frame.

The hollow integrated center shaft is an advanced type of center shaft at present. It integrates the center shaft and the crank of the dental disc, which not only improves the rigidity and strength of the whole dental disc system, but also reduces the weight. Hollow integrated axle has excellent performance, but it is also expensive, and is usually used on high-end bicycles.

Brand and quality:

Well-known brands of dental discs are usually more secure in terms of quality, performance and reliability. For example, Shimano, SRAM, FSA and other brands are well-known brands in the field of bicycle accessories, and their dental disc products have undergone rigorous testing and verification, with high quality and good reputation.

You can know the quality and performance of different brands of dental discs by looking at the evaluation of products, consulting the experience of other cyclists or referring to professional bicycle evaluation. In addition, some brands will provide after-sales service and quality assurance, which is also one of the factors that need to be considered when choosing dental plates.

Budget:

The price range of bicycle tooth plates is relatively wide, ranging from tens of yuan to several thousand yuan. Generally speaking, the better the material, the more advanced the technology and the higher the brand awareness, the higher the price of dental discs will be. When choosing a dental tray, you need to determine the appropriate product according to your own budget.

Don't just pursue low prices, because poor quality dental discs may affect the riding experience and safety; There is no need to blindly pursue high-priced products. For ordinary cyclists, some middle-priced dentures can already meet most of the needs.
