Let's talk about wired and wireless cycling stopwatches. Many friends like to measure their speed per hour and the distance of long-distance riding through the cycling stopwatch. Of course, it is very convenient to download the cycling notes to record the usual trajectory. But according to personal needs to install the cycling stopwatch, the current cycling stopwatch is mainly divided into two types of wired and wireless, do you think is the wired cycling stopwatch is better or wireless?
Main structure: Single pivot point system is currently the most common type of front and rear shock absorbers. The lever of this system only uses one bearing to connect to the frame, and the position of its upper bearing determines the riding performance of the car. Like Cross Country, the bearings are mostly at the height of the middle chainring; the bearing position of the freeride model is relatively higher and slightly forward.
Advantages: lightweight, cheap, and easy to maintain.
Disadvantages: easy to shake and easy to be interfered with by the transmission system.
Technology: Most of the Single pivot point system adopts a compromise approach, so it is recommended to use the rear shock absorber of the stepping platform.
The single chainset means that these 1x kits are relatively simple in structure, because there is no anti-dropping chain rod and front derailleur, which eliminates the possibility of the chain rubbing against the front derailleur, and they are quieter on the positive and negative gear discs, and the chain and the disc pass through a special Designed to engage the chain earlier.
The advantages of a single chainset: omit other discs and front derailleur, lighter weight; less gear shift coordination, more concise; omit the position of the front derailleur, more convenient maintenance of the chain gear shift, and reduced failure rate.
The disadvantages of a single chainset are limited to both the minimum gear ratio and the maximum gear ratio, which are not suitable for large slopes or high speeds flat roads.
There are usually two types of lock shoes, mountain bike lock shoes, and road bike lock shoes. What are the advantages and disadvantages of each? How to choose?
Mountain bike lock shoes, like mountain bikes, have strong terrain adaptability, mountain lock shoes were designed for use in various harsh environments, such as rainy mud, gravel roads, and so on.
Carbon fiber not only has the inherent characteristics of carbon materials but also has the soft processability of textile fibers. Its specific gravity is less than 1/4 of steel, but its strength is very strong. And its corrosion resistance is outstanding, it is a new generation of reinforcing fiber. Carbon fiber is widely used in civil, military, construction, aerospace, and super sports car fields.
