You worry too much. This is absolutely genuine. There will be no fakes in the flagship store, especially in JD.COM and Tmall. It is normal that the parts are not marked. You bought the whole vehicle, not the parts. Every industry is the same. Cars, computers and bicycles are actually a game between vehicle brands and parts brands. The bigger the brand, the less the bicycle will highlight the logo of parts brands, and it doesn't want to advertise for parts brands for free. Ferrari sports cars use Fuyao glass, but is there a logo of Cao Dewang Fuyao glass on the car glass? Shimano, a transmission manufacturer in the bicycle industry, is big, just like Toyota, but not every product is high-end, and there are many good parts manufacturers than Shimano. Now, many top brand bicycles in the world don't highlight the brand logo of parts, and Taiwan Province GIANT has begun to do so. Giant's car dentures, even handlebars, seat tubes, etc. are not marked, because if a car has too many parts, it will feel LOW. It's messy, with no grade and taste. Sports bicycles pay attention to cleanliness, simplicity, atmosphere and pleasing to the eye. Look at more world-class bicycles, almost all of which are more concise routes. Some top road cars have a logo on their bodies, while others are basically unmarked. This set is modeled after some luxury brands. Twenty years ago, mountain bikes were all in the front three sets, and road bikes were all in the front three sets or two sets of teeth plates. Now, the front three sets are all designed in a single set instead of the previous complicated three sets. This is the development trend of high-end bicycles in the future. Just like Apple mobile phones, the body is a simple Apple logo, simple and elegant, and the parts are carefully selected by excellent suppliers. As a world-famous bicycle, it provides quality assurance, instead of relying on parts brands to raise the price of its own vehicle and fight for configuration. Nowadays, more top bicycles have a simple LOGO on the frame, and more parts, such as wheels and handlebars, are no longer branded, just as the bags of the world's top brands, such as GUCCI Gucci and LV, are all simple logos. This is the trend, and the above is for reference!
