What are the advantages and disadvantages of disc brake and V brake?

First of all, there is a view that disc brakes are better than V brakes and should be high-grade-it seems that most people are not familiar with sports bicycles.

Hands often think that disc brakes must be better than V brakes. We have heard the saying: "There are more than 2,000 cars, and there are no plates yet."

Brake "-this really makes people laugh and cry. Watch both foreign competitions and domestic professional competitions.

If it's a sunny game, V-brakes are still the majority. Of course, there is also a trend to increase disc brakes at present, but right

For most leisure riders and cyclists who don't participate in amateur competitions, the V brakes, especially the better ones, are still enough.

Yes, of course, for cyclists who like downhill, hard riding and cool, disc brakes are still a suitable choice, but one

We still advise customers to choose disc brakes and V brakes from their own budgets from the perspective of use.

The choice is more reasonable.

1 Look at the difference from the design first.

The disc brake is braked by the clamp (or caliper) acting on the steel disc fixed on the flower drum; V-brake open

V-type brake caliper firmly grasps the rim to brake. Relatively speaking, the rim radius of the disc brake is much larger than that of the brake disc, so the brake disc

The brake arm of the brake is much smaller, so it is not easy to lock up in theory, which is the braking requirement of sports bicycles.

Generally speaking, it is the most basic, but it is not as simple as possible-unless you play rock climbing, which requires instant locking skills.

Sexual cycle.

1. 1 weight

It must be noted that, generally speaking, low-priced disc brakes are about 800g to 1kg heavier than V brakes, which is far behind high-end cars.

A little smaller. If the weight is listed separately, it can be seen that it is still an important factor affecting riding and has to be considered.

2 Look at the different characteristics of work

The friction of the V-brake is the contact friction between the rubber compound and the rim (generally speaking, it is the edge of the aluminum alloy car pin process, and the low-grade one is polished)

The side of the car, the so-called car edge and throwing edge, the car edge is better), generally the braking effect is still very strong, unless it is hugging.

Continue downhill at high speed and keep braking. For example, in Huang Ma, when we come to a fork in the road, it is also very important to touch the edge with our hands.

Heat, at which the braking force will be weakened. The higher the temperature, the worse the braking effect.

Disc brake is the friction between metal disc (usually made of steel and high-grade aluminum alloy) and disc brake friction block.

To brake, this kind of brake is very strong, similar to cars and high-end motorcycles, and its characteristic is that it is not affected by rain and bad roads.

The influence of the weather, because the disc brake friction block is a metal sinter, it rubs against the steel sheet, even if it rains.

In the muddy situation, the working condition is still good, and the braking force is obviously reduced, but it is stronger than the rubber aluminum alloy of V brake.

Gold ring friction. In addition, because the disc brake disc is made of steel and usually has holes, during continuous downhill braking,

With the increase of heat, the attenuation is better than V-type braking.

3 in terms of price, the so-called cost performance.

If it is a car with a price of 1000 yuan or more and a car with a price of 2,000 yuan or more, it is recommended to use a V brake. Almost all experienced people say so.

Low-priced disc brakes are not as good as medium-priced V brakes. Explain this sentence first. The price of low-priced disc brakes is 2.

00 yuan to 300 yuan, including some Taiwan Province brands such as assess, promax, etc. And even gaskets.

Ano officially sells 475,495 disc brakes with a price of more than 500 yuan, and the effect is very general, among which the quality of Shimano.

The quantity is good, but it feels hard. Generally, if customers want to install disc brakes, although these disc brakes are available in mountain bike dealers.

Goods, but generally we recommend, unless it is a child who must let it cool, there is so much money and money to let it cool, not.

Whether it is sold or not, customers who have newly loaded cars rarely recommend it; V brake is very popular because there are many brands to choose from besides Shimano.

You can easily achieve mid-range braking effect without spending too much money, such as the classic Avid FR5 double-sided embossed brake handle+

Shimano M430 brake caliper, the price of such a set of brakes is only 247 yuan, but the feel is far better than this.

Those disc brake systems above are much better, if there is more budget, the same avid fr5 brake handle, but

High-grade V brakes with avid sd7 (simple brake block version in 300 yuan, hardcover version in 380 yuan, is already sexual.

It can be a very good v-brake, so the whole braking system only costs 400 yuan, but it is already a high-grade brake.

System, no need to upgrade, of course, you can also choose avid brake handle plus Shimano's old Lx-class V brake.

Combined use, of course, Shimano high-end V brakes are officially expensive, so the old LX is still more cost-effective, and

Moreover, the braking force is relatively large, and these combinations are very good. On the other hand, the disc brake system with the same price: for example, our common Shi Man.

O EF 29, EF35 and EF50 series handbrakes are broadcast at the same time, if matched with Shimano 475 disc brakes-such a modern moneymaker.

The price of 680 yuan is the same as that of Shanche, and it's still messy in 540 yuan (before the loading discount). It feels very hard.

A trip to the mountain road made my hands sour, and the garage met many customers who matched this in daily maintenance.

This kind of rider upgrade is often costly and painful.

If it is a car disc brake with a price of 2,000 to 3,000 yuan, take it easy (a good disc brake is also very important, but it involves

The problem of walking system), the entry-level disc brake we recommend is the so-called cost-effective disc brake like Kazakhstan.

Yes's 2004one black version, hayes' mx2 and Avid's BB5, the former price is in 520 yuan, and the latter price is in.

620 yuan, these two products, such as Avid, which specialize in making disc brakes, are still very strict and feel acceptable.

The feel of BB 7 disc brake is still a lot worse, but the quality is stable and the control of feel strength is still very clear.

Yes, plus a slightly better disc brake hub, the price of the whole vehicle is more ideal than that of 3k, and it is of course a higher-grade disc brake.

For example, avid's BB7 cable tray and shimano deore's 525 oil tray are all good choices.

choose

To sum up, actually buy a new car and upgrade the brake system.

For young people, they must ride mountain roads in mountainous areas. If the budget is in place, they can choose disc brakes. If the budget is in place,

1k to above 2k, or V brake is more affordable. After all, where is the total budget? This is robbing Peter to pay Paul, right? If a person

I began to think that I should choose the right flower drum with disc brakes in the future, otherwise it would be troublesome to upgrade in the future!

For girls, the elderly and leisure cyclists, V-type brakes are more suitable, light in weight and easy to maintain.

For the upgrade, the configuration and price of the original car should be considered as a whole. Many people say it will cost some money to upgrade the brake system.

System, "Give me a disc brake!" Later, it was found that the flower drum, frame, front fork, etc. had to be changed. Alas, the price is too high.

The big one, the second best, or spend less money, 200, 300 yuan, change a set of mid-range V brakes, which is very good.
