Have you read the original poster’s question upstairs? Hello, original poster, since they are all geared, it doesn’t matter who is faster. Because vehicle speed is affected by many factors, such as front and rear gear ratio, tire pattern, and rim size. , road surface, air resistance, etc. Indeed, some people say that among cars in the same price range, Giant is easier to ride and is relatively "faster" because the workmanship of Giant is better than that of ordinary cars, and the steel and aluminum used for accessories are harder. , the tires are mostly new, the rubber is relatively durable, and the shock absorption effect is good. In this way, the pedaling is not particularly empty and does not waste too much energy. So when it comes to speed, at least it depends on the front and rear gear ratio of the speed change. As long as the front is larger and the rear is smaller, It's fast to pedal, but it's laborious. Therefore, whether it's a Giant or not, you can reach high speeds. Among bikes of the same price, the Giant is easier to ride, so you should give it priority when buying a bike. I can't say whether the chain is good or bad, because its It is a consumable product in itself. Many Giant's 24-speed bikes use SHIMANO IG51 chains, which cost more than 30 yuan. It is no problem for general road riding, and it is also fine for rural dirt roads. You have to be careful off-road, as the chain is not strong enough. In addition, it is easy to disassemble it randomly. The chain will also collapse because the chain links are riveted in. If the chain cutter is not installed properly, the force on the chain will be uneven. As long as you exert force while riding, it will easily break. It will fall off. So you need to take more care, wipe it frequently, and don’t disassemble it randomly.
