Let's start with a giant mountain bike. The price is about 1600. Give me some advice.

atx690！ Mine is, but the front fork shock absorber is rubbish and can't be adjusted yet.

660 670 may not be available in some stores, but it is not available in the store next to Shanghai Workers Hotel. .

Performance of 690: Japanese Shimano ALTUS m3 10 7-speed dial-back device, low-end entertainment level, ALTUS is a 7-speed high-end device.

The border feels ok, but it feels a little awkward after using it for a long time.

The tires of the new 690 seem to have been changed. The previous one was too shaky. This is also used in a car in cst Solomon.

Yan Hao V-brake is good, but I changed it to Shimano m42 1 v-brake. . .

In short, the cost performance is average,,, or you can see what model the Duke of Merida series has forgotten. In short, the cost performance is slightly higher.
