Of course, there is no need to buy a whole car. Tell you what, I'll give you some advice.
If it is around 15000, you can buy it in the garage. Fox big kit is about 6000 RMB, as long as the frame looks good. In my opinion, carbon frames and aluminum frames are similar, but whatever you want, the price of carbon frames is around 4000, and aluminum frames are already high-grade goods. Whatever you choose. The minimum set of Marwyck for wheelsets is about 1500, which is enough for you. Nothing else. If you want a front fork, the price of the new 35 1 front fork pneumatic fork is around 1800.
I'll give you a configuration of around 4000.
Santuo Shencha: 800
445 oil dish: 450
Wheel sleeve (3 15 steel ring, long-awaited flower drum): about 800, (Taobao parallel 500)
Landlord 590 dental tray: 450
Paragraph 9: 160
9-digit speed dial: 240
Frame: 500 to 700, just look, which one looks good. The quality is not much, but it will not be broken or cracked anyway.
Maxxis folding tires: a pair of Taobao 350, about 400 in a physical store.
It doesn't matter whether the chain is horizontal or not. The important thing is that I told you about the brakes, front fork and wheel set.
If you have money, just buy a big kit and wheelset. There is no need to go to so much trouble.
It's been a long time.
Just typed it, just as the answer.
