Is it cost effective to buy 11 Giant ATX770D at a price of 2598 glossy black .

**It's okay, the physical store is this**, if you are using it to go to school, if you have to choose accessories, the first choice is foot support, locks, gloves, and computer watches, but in fact, these things can be bought cheaply elsewhere, because 260 yuan** can't buy too affordable things in the store.

When picking up the car, it is best to copy a detailed configuration of the car in advance, and then compare it on the spot to see if it is consistent, and what is the quality of the things promised to be sent, whether it is Giant's own brand or brand, do not buy a copycat, keep the warranty certificate, etc., to facilitate the warranty in the future, and then see if the car is brand new, it is nothing.

Helmets and gloves are preferred, followed by size gauges.

Bottle cages, car lights, etc., but for 20-30 yuan, it's best to buy them yourself online.

Foot braces, bottle cages, kettles, flashlights, tail lights, helmets, these are more practical!! There is no need to install the fenders·· It's not beautiful! Pay attention to whether there is a problem with the frame when picking up the car! There will be a guarantee when you buy it in a specialty store!!

The national uniform price is on the official website of Giant**, and the in-store manual is also printed**.

When it comes to equipment, consider safety gear first, such as helmets, gloves, etc. The second is the body equipment, such as: computer watch, bottle cage, lights, etc., which can be matched as needed.

The specialty stores are all genuine. Rest assured. If you want to save a car, it will be very cheap. With a fake Giant frame

1.It's really hard to say the cost performance, but now there are obviously more people who buy 770D than those who buy 770, and the difference in configuration is mainly in the brakes, crankset, and wheels

2.It has been said for several years that the 770d is a chicken rib, and since last year, the 770d has surpassed the 770 in an all-round way. (The 770D in the early years had one more disc brake than the 770, but the front and rear derailleurs were one level lower than the 770).

3.After a period of use, the disc will be more or less deformed, which is unavoidable (unless you use a floating disc). But generally speaking, the deformation of the disc will not have an impact on the braking performance, but if the deformation is serious and without debugging, the disc will rub against the disc when riding to produce sound, but the position of the brake caliper can be avoided by general debugging, and such debugging will not be very difficult.

The wire disc does not require too much so-called maintenance, but it is best to adjust the position of the lower caliper and adjust the plate after a period of time, so that the brakes can be kept in the best condition. It is time to replace the order piece when it is almost worn, and this is specifically based on the frequency of use, the general braking frequency is not very high, and it is not often to go to the slope, so that the plate can be used normally for 1-2 years.

The difference between the 2012 ATX770 and the ATX770D is that the V brake is replaced by the BB5 disc brake The transmission is the same, and it is one level stronger than the 11 model.

Mine is the ATX770D, the brake system is different, this is the disc brake.

The transmission is generally out of the way, and in the city riding are used front 3 and rear 6-8.

Good maintenance, the noise is normal, it does appear, my front disc brake sometimes rings.
