2, look at the suite, the suite is basically several sets. Every family has a different model. Look at the level of the kit and you will know the positioning of this car. For example, the most common Shimano: 1, competition: entry-level entertainment; 2.altus: entertainment level; 3.acera: entry level; 4.alivio: entertainment level; 5.deoer: training level; 6.deoreLX: special for station wagons; 7.deoreXT: competitive entry level or XC training top level; 8. sage: committed to downhill or am; 9.XTR: The competition is the fiercest. What level of kit do you think this car is? This car is about that level.
Of course, grade is not directly related to quality. Middle school students don't have to use top competitions to go to school, do they? Grandpa doesn't need to ride a training class to buy food in the vegetable market, does he? This is not good. Because that car can't be easily shelved, it can't pull too many vegetables and rice. Ferrari is not necessarily better than tractor, let's see who plows the field faster. Right? Good and bad, different standards, good and bad results are also different.
3. Look at the brand. There are technologies, patents, processes and material applications behind the brand. A strong brand can lead the direction and trend of cycling. The application of every new technology and new material is ahead. Whoever is the forerunner and leader is the strongest and best. It depends on the brand story. Why is the lightning brand bigger than permanent in the field of sports bicycles? Lightning has been leading American road cycling for decades.
