Now with the rise and development of bicycles, more and more bicycles are equipped with a shifting system and have a shifting function. Since this function is available, of course we cannot waste it or use it indiscriminately.
Generally speaking, low gear ratios are used for climbing, medium gear ratios are used for acceleration and cruising, and high gear ratios are used for full acceleration. The basic principle of using the edge degree system is to try to use low and medium gear ratios and pedal more easily instead of using high gear ratios to pedal hard. This will not only achieve the most labor-saving effect, protect your knees, but also make the chain less stressful and protect the transmission system.
Most gear shifting systems will have an indicator window at the shifting hand dial. We can directly understand the current gear position through the window. However, it is best to exercise yourself and judge the gear position based on your feelings. This is much more convenient than viewing the window. . What the bicycle factory wants everyone to remember is that the small flywheel at the back is in the high gear, and the small chainring in the front is in the low gear. Try to avoid using the largest or smallest gear. For example, on a three-piece chainring bicycle, you should avoid using a large chainring in the front and a large flywheel in the back.
