It is genuine, and there will be no fakes in flagship stores, especially JD.COM and Tmall. It is normal that parts are not marked. You bought the whole car, 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 the component brand, and it doesn't want to advertise the component brand for free.

Shimano, a transmission manufacturer in the bicycle industry, is very big, just like Toyota, but not every product is high-end. There are many parts manufacturers that are better than Shimano. Nowadays, many top international brands of bicycles don't highlight the brand logo of spare parts, and Taiwan Province Giant has also started to do so. Giant's automobile dentures, even handlebars, seat tubes, etc. None of them are marked, because if a car has too many parts, it will feel low. It's a mess. It's classless and tasteless. Sports bicycles are clean, concise, atmospheric and pleasing to the eye. See more world-class bicycles, almost all of which are relatively simple routes. Some top road cars have logos on their bodies, while others are basically unmarked. This set is modeled after some luxury brands. Twenty years ago, mountain bikes were the first three sets, and road bikes were the first three sets or two sets of teeth. Now the first three sets are all single sets of design, not the complicated three sets before. This is the future development trend of high-end bicycles.

As a world-famous bicycle, it provides quality assurance, rather than relying on the brand of parts 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 components, such as wheels and handlebars, no longer have brands, just like the bags of the world's top brands, such as GUCCI Gucci and LV, are simple logos. This is the trend, and the above is for reference only!
