Help analyze the second hand Giant 660, can you get it?

It feels like a 550 or 580 should be a deal, but you have to look carefully to see if the frame, pressure plate and tires have been cleaned up or damaged, especially to see if there is a problem with the bottom bracket. Good luck.

600, more than a year, almost. It's still okay to take a knife. When looking for the hard wound on the car, he pointed and said: Brother, let's hurry up, 500 deal.

The main thing is to look at the frame, the shifting. You can change the rim to a carbon fiber one, (don't change it if you're not playing professional), and there are inner and outer tires, 8 into new ones shouldn't have much wear.

First, see if any parts have been replaced by the original owner, that is to say, you must be familiar with the configuration of 660 in advance.

Second, see if the frame is bruised, whether the transmission is smooth, whether the rim is positive, whether the crankset is flat, and the spokes should also be carefully checked!

Third, look at the wear and tear of the tires. If the wear is serious, cut the price more.

OK. 20% off on the ground, and then press the price according to the fineness. It's worth buying a brand service!

The main thing is to see if the car has been injured or not, and whether the parts have been replaced, ** depends on the seller, and discuss with him to see if you can reduce something or something, and it is estimated that you can return some.

Is it an electric car, it's very good, if the battery is good, it's okay, try it first.
