Bicycle Transmission Principles and Techniques (2)
On a flat road, the front chainring is usually a small chainring, mainly with the rear chainring 17 to 21. If riding in a downwind condition, the rider can adjust the front to the larger chainring, and the rear chainring can be adjusted. Free matching to achieve the effect of high-speed cruising.
In the riding plane section, if there are sharp short slopes ahead, such as bridges, hilly terrain, etc. The rider can rush up by virtue of the inertia of the riding plane section, the front chainring can be maintained at the position of the large chain, and the rear chainring should change gears according to the road conditions.
Since it will increase the burden on the legs of the rider when stepping on the uphill section, the resistance of the legs will be too large. At this time, the gears of the rear disc should be adjusted. At the beginning, use the adjustment method of one tooth and one tooth to gradually find the most suitable gear. With the experience of riding later, you can easily find the suitable gear.
On a continuous uphill section of riding, the rider should change gears according to the terrain. Usually, the front chainring is adjusted to a small one, while the rear chainring is constantly changing gears to match the rapidly changing terrain conditions.
When a beginner is riding a continuous downhill section, the first principle should be to maintain an average pedaling efficiency and avoid affecting the vehicles behind. The front chainring can be adjusted to the large chain, and the rear chainring can be gradually lowered. Do not adjust it because of greed. If there is an unexpected situation or a sharp bend, the braking will not be enough, which may lead to a serious accident.
In fact, there is no so-called correct shifting timing during the riding process. After all, everyone's physical conditions are different. Riders should listen to and feel the level of their riding to change gears. In simple terms, you should change gears when you feel resistance when riding, and you should adjust the gears if you pedal too hard, and vice versa.
