Bought a 2010 Giant ATX790 and don t know how to test performance? How to buy and solve!!!

First of all, see if the frame is suitable for your figure, 170cm or so 16 inches, 180cm or so 18 inches, and then try the feel of the speed and brakes, the feel is not good, that is, the speed is not accurate or smooth, indicating that the speed needs to be adjusted or the line pipe is oiled, if it is serious, you need to replace the transmission line and line pipe, the same is true for the brake, the feel is not good, that is, the feel is stiff or astringent, the line pipe needs to be oiled, or replace the brake line and line pipe, and then look at the brake pad wear to decide whether it needs to be replaced, and then try the fork, Ride a lap to see if the suspension performance of the fork is good, the judging criteria, the absorption of bumps and the efficiency of rebound, and finally look at the frame, which should be judged by yourself. Good luck with a good car!

Hello Mountain Bike Bug Tour" will be happy to help you with your questions about mountain bikes, and our team welcomes you to join

How to buy? Before buying a car, you should have a good understanding of mountain bikes, such as what you are buying a mountain bike for (long-distance or off-road?). ), the choice of frame size (you have to consider your height, hand and leg length?)

and so on, as well as how much budget you have for the purpose of purchase, you can buy a mountain bike that suits your configuration Choose a model first, the performance difference of a new car will not be very large, and the performance of the performance after the run-in has a lot to do with your own maintenance

Test performance? After buying a car (I just said that the performance difference of a new car will not be very large, and the performance after running-in has a lot to do with your own maintenance).

Make sure your car is in the best condition and can perform performance tests on both flat and mountain grounds

Flat performance test: mainly acceleration ability, hub moisture, etc., find a similar mountain bike, let your friend and you accelerate as much as possible in the same gear, and then compare the distance of taxiing after stopping acceleration (of course, this is not only related to the drivetrain and hub, but also related to weight).

Performance test in the mountains: mainly the ability to shift, fork performance, brake feel, etc., in the field uphill section of the continuous speed change test of its smooth and accurate shifting, in the downhill section to test the fork performance, braking force and brake thermal attenuation performance

Let's mention so much first, if you still have any questions, welcome to communicate**

Just ride five kilometers and you're done.

Summary: With the high-grade bearing structure of Giant, it can be significantly faster than the ordinary ball structure hub when going downhill, and it will be more labor-saving to ride on the flat road.

The frame is finely painted, and I personally feel that the painting of the frame details is better than that of the ATX870, which is also an 8 series frame.

The effect of the sandblasted giant pattern on the tube can be described as gorgeous, and the unique reflection of the golden sandblasted in the light shows the nobility.

1.Strong bumpy feeling when riding.

The Giant ATX830 is positioned as an off-road mountain bike, so its body structure and suspension system are relatively stiff and supportive. While this gives the rider a better sense of control and stability, it also leads to a bumpy feel. Especially when the road is not very smooth, the riding experience will be worse.

In addition, some buyers reported that the fork travel of the car was short, which also increased the degree of bumpiness.

2.Accessories are more expensive to upgrade.

The Giant ATX830 comes standard with basic equipment, such as the brakes and wheels. If the user has high requirements for the performance and configuration of the bicycle, it will need to be partially or fully upgraded, which will bring high costs. For example, users may need better brakes, more comfortable saddles, and lighter wheels, all of which need to be reinvested and higher.

3.The fork can't lock up.

For mountain bikes, the ability to lock the fork is very important. When the rider needs to go downhill or step over an obstacle, etc., the fork can be locked to make the vehicle more stable and controllable. But unfortunately, the front fork of the Giant ATX830 does not support the lock function, which is a big regret for users with certain technical requirements.

4.The frame weight is heavier.

The frame of the Giant ATX830 is mainly made of aluminum alloy, which is relatively heavy. At the same time, the shape of the frame is also relatively old, which is slightly less than some modern mountain bikes. As a result, the Giant ATX830 struggles when it comes to long rides and fast climbs.

Summary. The above are a few obvious shortcomings of the Giant Youyin ATX830. If you're looking to buy an off-road mountain bike, it's a good idea to consider your needs and budget before choosing the Giant ATX830.

If you're just touring or relaxing in the lobby, then the ATX830 is a good choice; However, if there are higher requirements for speed, performance, and configuration, you need to consider other more professional products.

The oil disc brakes are different for the ATX870 and the Shimano 395 for the ATX890 (the ATX890 is a bit higher).

The gearboxes of the two cars are slightly different, but they don't have much impact.

The ATX890 is a few hundred dollars more expensive than the 870.

Entry-level models, see which livery you like to buy.

Giant's car is not cost-effective, more than 10,000 can buy a Ka100 of the gallop, carbon fiber frame, 10 years of shelf, competitive mountain. Buying a Trek 6500 is also better value than Giant. Giant (English:

Giant, Taiwan Securities Exchange: 9921) is a brand founded by Taiwanese bicycle manufacturer "Giant Machinery Industry Co., Ltd.", and is one of the internationally renowned Taiwanese brands. "Giant" is a transliteration of "giant", and the manufacturer "huge" is its paraphrase.

Juju Machinery was established by Liu Jinbiao in 1972 in Dajia Town, Taichung County (now Dajia District, Taichung City), founded the "Giant" brand in 1981, and established "Giant Co., Ltd. ****" to be responsible for business sales, with global production plants in Taiwan, the Netherlands and Chinese mainland. The company was listed on the Taiwan Stock Exchange in 1994.

Let's take a look at the specific configuration of the two cars first:

You can see that the main thing is that the oil disc brakes are different, the ATX870 uses HDC300, and the ATX890 uses Shimano's oil disc brakes better.

The rest of the differences are not big, if you buy, you can take a look at the paint and choose the paint you like.
