Xidesheng Tiantian300 2018, which is better than giant atx660?

I am a veteran mountain bike player (1992, the first Taishan mountain bike, Spetzman, with a speed of 15), and now I have two XC-class hardliners (Dokas-like giants, which are also one of the big manufacturers in Taiwan Province Province, and the carbon bike action M2 has been changed to mountain bikes, which are "road-riding mountain bikes"; American stunt 19 carbon frame procaliber 9.6, used for cross-country and sometimes participating in local small-scale competitions), 1 AM soft-tailed mountain bikes (Process 156DL from Kona, USA, used for playing in wild mountains) and entry-level bicycles, such as giant ATX series and Merida warriors, have also been ridden. My suggestion is to choose Xidesheng at the same price, which is more cost-effective (such as gearbox kit and front fork will be better). After all, we support domestic products (Giant Merida belongs to Taiwan Province Province and China, but it is still different from the mainland at present, so it can't be completely counted as domestic products). Mei Jie and the United States are more inclined to the second (qi) attitude towards the domestic market (for example, I bought SL 1 last year). Through research, it is found that the whole 19 Challenger series frame, although the United States officially promotes the new frame and new geometry, my riding feeling is better than 20 15 and 201. ; For example, 20 18 and 20 19 models of high-end XTACADV carbon fiber frame cars are all 29-inch supercharged specifications. They have been sold abroad for more than a year, but they have not been sold to China. What is sold in China is the 27.5-inch old specification since the 20 14 model, with slight changes, upgraded speed change kit, etc., called 18. But in fact, it is not the same as 18 and 19 sold abroad. Last year, I wanted to buy XTACADV of the giant's boost specification, but I didn't ask several stores. I sold XTACAD V 1W7 (technically no different from the 20 14 model). Finally, I ... . What is boost? The front and rear gears (that is, the distance between the front fork and the rear fork on which the wheelset is mounted) have been increased from the traditional 100 mm and 135 mm to10 mm and 148 mm, and the central axis has also been widened. The relevant important accessories include the front fork and the toothed plate, both of which are available. Starting from 20 17, mountain bikes in Europe and America began to popularize 29-inch ++boost, followed by giant Merida, but only sold in Taiwan Province Province and Europe and America, and only sold its outdated specifications and models in China. Therefore, it is better to support xds (although the brand image of XDS in the player circle is not as good as that of giant Merida). . . Finally, as beginners and entry-level cars (less than 3000 cars are counted), big brands have low cost performance and no technical content (including lightning and Rick's cars), and they can neither ride well nor break down. I hope XDS will live up to expectations, work hard, make itself the first sports bicycle brand in China just like Korean cars, and promote new technologies and specifications.
