From "four wheels" to "two wheels", what kind of magic will bloom?   On May 4, the 18th Beijing International Automobile Exhibition came to an end in Beijing; One day later, the 32nd China International Bicycle Exhibition opened in Shanghai. One north and one south, "four rounds" and "two rounds", echo each other.   The data speaks for itself.   China is a big producer of bicycles, accounting for about 60% of the world's annual trade. In 2023, China produced 48.83 million bicycles and exported 39.648 million.   The exhibition data is also wonderful - more than 1,400 enterprises participated in the exhibition, more than 7,300 booths were open to the public, and more than 100 overseas buyers came to discuss cooperation... The small bicycle has aroused great concern in society.   Speaking of bicycles, they have a history of development in China for more than 100 years. The bell rings, the wheel turns, and the "two wheels" span not only the distant distance, but also the changes in people's ideas.   Once upon a time, the bicycle was not only a sought-after means of transportation, but also known as the "four major pieces" with watches, sewing machines and radios, which were precious objects in the homes of ordinary people, and a "twenty-eight bars" carried the memories of The Times.   Nowadays, with the low-carbon concept deeply rooted in the people's heart and the rapid development of technological level, bicycles are not only a means of transportation, but also a combination of technology, fashion, social and other attributes, and become a part of people's green life. "Bicycle Kingdom" opens up a new track in the new era.   -- Innovation, so that the bicycle "ride" more intelligent.   The motion mode is scientific, the speed change process is crisp, and a set of hydraulic disc brake transmission for gravel road vehicles on the Suiruida booth has attracted a lot of visitors. "It changes speed with a flick of the finger, and the operation is very user-friendly." Liu Weibing, general manager of Fast Ruida Bicycle Parts (Foshan) Co., LTD., told reporters that the transmission technical barriers are high, and the team spent five years on technical research.   At the exhibition, the cutting-edge scientific and technological achievements of the bicycle industry emerged in an endless stream: the 3D printed titanium alloy frame is lighter and higher strength than the traditional welded frame; A one-piece flywheel that weighs as much as a glass of water but has the strength of an aluminum-lithium alloy; Support the connection with the mobile phone operating system, with map navigation, heart rate monitoring and other intelligent functions of the electric assisted bicycle...   "These results show the new achievements made by the bicycle industry in intelligent manufacturing and other aspects, and also reflect the trend of the industry's gradual transformation to high-end, digital and branding." China Bicycle Association vice chairman and secretary general Guo Wenyu said.   -- Green, so that the bicycle "riding" more environmentally friendly.   A small paint used to color car frames has the potential to reduce carbon emissions.   "The pure water-based single-liquid PU coating is baked at 95 degrees Celsius, lower than the current standard of 130 degrees Celsius, and can reduce carbon energy consumption by a quarter." Zhang Yu, head of the innovation demonstration exhibition, said that the new coating products use pure water instead of solvents, and can also reduce environmental pollution to a certain extent.   The concept of green environmental protection has not only created new growth points for enterprises in the production side such as raw material selection, but also reflected in the consumer side.   In 2023, the number of cycling-related videos played on the Tiktok platform increased by 94.4%, the search volume of cycling-related content increased by 137.4%, the sales of high-end sports bicycles on the market increased by more than 10%, and disc brake road bicycles have become mainstream products sought after by young people.   "More and more people are choosing to commute and exercise by bike, and green travel is becoming a common trend." China Bicycle Association industry development director Zheng Xiaoling said.   -- Open up, let more bicycles "ride" out of the country.   "Our company plans to purchase 60 containers of electric bicycles in China this year and sell them to Saudi Arabia, the United Arab Emirates and other countries, three times the amount purchased last year." Aak, a buyer from Yemen, said that Chinese electric bicycles are one of the most favored products for overseas buyers.   In the first quarter of 2024, China exported 10.99 million complete bicycles, an increase of 13.7% from the fourth quarter of 2023, and exports showed an upward trend. "More and more enterprises are focusing on expanding overseas markets, and the influence of domestic bicycle brands is constantly improving." Zheng Xiaoling said.   Innovation is the driving force, green is the direction, and openness is the trend. Facing the future, the "bicycle kingdom" will "ride" to a better distance on the new track.   

Bicycle butyl rubber inner tube refers to the bicycle inner tube made of butyl rubber as the main material. Butyl rubber has many advantages, making it an ideal material for the manufacture of inner tubes. First of all, butyl rubber has excellent air tightness, which means that it can effectively prevent gas leaks, ensuring that bicycle tires can maintain stable tire pressure for a long time after inflation.

At present, the size of bicycle tires mainly follows the European standard ETRTO (European bikeTire gauge Technical Organization) or ISO standards. However, the Old English and French labels are still used in some cases. Taking 37-622 as an example, according to ETRTO standards, the bicycle tire width is 37mm and the tire inner diameter is 622mm. The inch mark (e.g. 28 x 1.40) indicates that the outside diameter of the bicyle tire is 28 inches and the tire width is 1.40 inches. Another common notation is 28 x 1 5/8 x 1 3/8, which roughly represents the outside diameter, tire height, and bicycle tire width. It is important to note that inch measurements are not very precise. For example, tires with a diameter of 559mm (mountain bike), 571mm (triathlon) and 590mm (station wagon) are all classified as 26 inches. Both 622mm and 635mm diameter tires are defined as 28 inches. Even weirder, a tire with an inner diameter of 630mm is defined as 27 inches. These definitions stem from the era of bicyle tire brake pads, when the exact outside diameter of a tire was determined by the brake pads. A variety of inner diameters are defined according to different bicyle tire widths.

The performance difference between the multi-speed sprocket and the single-speed sprocket of the MTB Triple Chainwheel & Crank Set in mountain bikes is mainly reflected in the following aspects:Speed change range and adaptability:Multi-speed sprockets offer a wider shifting range, allowing riders to adjust gear ratios for different terrain and riding needs. This means that whether climbing a steep hill or descending at high speed, the rider can find the right gear ratio to optimize riding efficiency.Single-speed sprockets have only a fixed gear ratio and cannot be adjusted based on terrain or needs. It's better suited for certain types of riding, such as urban commuting or flat-road riding.Gradeability:When facing steep hills, the low gear of the multi-speed sprocket can provide greater torque, making it easier for the rider to climb. Riders can switch to a lower gear ratio to take the load off their legs and maintain a consistent speed.A single-speed sprocket may struggle when climbing hills because the rider cannot adjust the gear ratio to relieve the load on the legs.Downhill speed and control:When going downhill, the multi-speed sprocket's high gear allows the rider to reach higher speeds and provides better control. The rider can adjust the gear ratio as needed to maintain a steady speed or accelerate.Single-speed sprockets may limit a rider's speed when going downhill because the fixed gear ratio may not provide adequate speed range.Maintenance and durability:Multi-speed sprockets may require more frequent maintenance and adjustments because they have more gears and shifting mechanisms. Improper installation or adjustment may cause problems such as sluggish shifting or chain detachment.Single-speed sprockets are relatively simple and easier to maintain. The lack of a shifting mechanism reduces potential points of failure, making it more durable.Price and cost:Generally speaking, multi-speed sprockets and cranksets will cost more than single-speed sprockets because they contain more parts and more complex technology.Single-speed sprockets are relatively more affordable and suitable for cyclists with a limited budget.Therefore, the performance difference between multi-speed sprockets and single-speed sprockets in mountain bikes is mainly reflected in the transmission range, climbing ability, downhill speed and control, maintenance and durability, and price and cost. Riders can choose the right sprocket type based on their needs and budget.

When choosing a bicycle cassette sprocket, there are several factors to consider that can help you find the right one for your riding style and needs. Here are some guidelines to assist you: Compatibility: Ensure that the cassette you choose is compatible with your bike's drivetrain. Check the number of speeds (usually 7, 8, 9, 10, 11, or 12) and type of cassette (Shimano, SRAM, etc.) that your bike's rear derailleur can handle. Gear Range: Evaluate the terrain you typically ride on and determine the appropriate gear range you need. A wider range with larger low gears is suitable for hilly or mountainous terrain, while a narrower range can be more efficient for flatter or smoother roads. Number of Teeth: Consider the number of teeth on the individual sprockets in the cassette. Smaller sprockets (with fewer teeth) provide higher gears and are optimal for speed on flat terrain, while larger sprockets (with more teeth) offer lower gears for easier climbing. Gear Ratios: Examine the gear ratios offered in the cassette. Ideally, they should be evenly spaced to provide smooth gear transitions and allow you to find the right gear for any given situation. It's beneficial to have smaller jumps between gears in the range you use most frequently. Weight: Weight can be a consideration if you're aiming to reduce the overall weight of your bike. Higher-end cassettes often use lighter materials like titanium or have cutouts to reduce weight. However, keep in mind that weight savings usually come with a higher price tag. Budget: Set a budget for your cassette purchase, as they can range significantly in price. More expensive cassettes often offer better materials, smoother shifting, and increased durability, but there are also reliable options available at lower price points. Brand and Quality: Stick with reputable brands known for producing quality components, as they tend to have better manufacturing standards and product support. Popular brands like Shimano, SRAM, and Campagnolo offer a wide range of options to choose from. Remember that choosing the right cassette sprocket is a personal preference based on your riding style, fitness level, and the terrain you ride on. It's a good idea to consult with a knowledgeable bike shop or a bicycle mechanic to help you make the best decision based on your specific needs.
