1, tire

Highway 700C is equivalent to 28 inches, and the mountain is 26 inches in wheel diameter; The tires of mountain bikes are usually above 1.9 "(you can choose 1.5 under special track), while the tires of road bikes are mostly about 20 mm wide.

2. Handlebar control parts

In order to ride on rugged mountain roads, wide handlebars are used in mountainous areas, while expressways pursue speed and reduce wind resistance, so handlebars are narrow.

3. Basic framework

In mountainous areas, the combination of light and heavy is considered in bumpy roads, and the emphasis of highway consideration is the rigidity and portability of trampling. Road bikes are usually slender (in recent years, the frame based on aerodynamic design is thicker), while mountain bikes are stronger. The angle of mountain bike frame is very particular, and the angle of road bike is similar. Mountain bike axles are thick, while road bike axles are thin. At present, with the application of manufacturing technology and high-tech materials, it is difficult to find any similarity between the two frames except the basic structure.

Step 4 brake

Mountain bikes need a powerful all-weather braking system. Early mountain bikes used suspension braking system, and later V-type brakes provided better braking performance. At present, the best braking system is the disc brake imported from motorcycle, or disc brake. In addition to braking strength, the most important thing for road vehicles is light weight.

5. Front fork

The front fork of mountain bike is an important part of mountain bike, which is high in technology, rigid and lightweight in performance and comfort, while the front fork of road bike is only a part related to the frame.

6. Weight

Weight is very important for mountains and roads. During the race, the mountain bike can reach 12.5kg, while the maximum limit of the highway is 10.5kg. The heavier the bike, the more work you consume, which will inevitably increase your redundant consumption.
