Dynamic Performance Of Carbon Wheels
Jul 11, 2017

In the video broadcast on the Big ring, you can see the drivers using the carbon wheel, the top tube tire aluminum wheel although found, but it is extremely rare. In civilian circles, many manufacturers claim that a carbon knife can significantly save your power and improve your performance.

Is this the value of the carbon wheel? is its value worthy of its price?

The chat between the friends of the car will be pulled to upgrade the equipment, and many times the topic will always transfer to the upgrade of the wheel group. In fact, Carbon Wheels more and more fans feel that changing a pair of wheels is better than changing a kit or something else to improve their athletic performance. There is an inappropriate analogy: Many enthusiasts feel that the wheel group of a road car is the engine of a car.

The performance of the major round plants has been booming over the past decade, and I guess it's not unrelated to the many drivers ' impulsive escalation of the wheel group. Carbon Wheels The market for the carbon fiber wheel at the top of the pyramid has been particularly significant. They claim to be able to save time and power considerably, helping drivers get better grades-as if you had to change a pair of carbon knives and your car would be loaded with nitrogen acceleration. In this respect, the carbon wheel's "cost-effective" is really quite high. In particular, the high-end market is almost saturated now, Carbon Wheels the cheaper carbon fiber wheel group has begun to compress the aluminum alloy wheel group's living space. I don't know if the aluminum wheel will be like aluminum frame, by the market gradually compressed to the bottom until fade out, but I don't think there is no chance. 15 years ago, Carbon Wheels the drivers agreed that the carbon fiber frame could not be popularized on a large scale because carbon fiber materials were too expensive to prove performance and unreliable in the competition. But now ... The world's top lightweight obermayer, the same top price

Declaring value

According to the market, the important value of the carbon fiber wheel is its lightweight weight and better aerodynamics. The lightweight advantages of carbon fiber are well known. And the wide-body process of the wheel group started by the major manufacturers has also strengthened its aerodynamics. The middle of the 90 's campagnoloshamal frame high 40mm, the weight of 1980g, was considered to be incredibly high. Now, Carbon Wheels over 50mm, the weight of the carbon wheel Group is almost no more than 1500g. Carbon fiber has only one color, but different carbon fiber arrangement can get different appearance

Another advantage of carbon fiber is that it can be molded into various shapes through mold precision. With the help of Hydrodynamics model, Carbon Wheels computer simulation and real wind tunnel test, the shape of the carbon wheel can achieve the limit of the factory's ability. Publicity breaking wind and wind resistance is now the main direction of carbon marketing, Carbon Wheels and these capabilities can be sorted by quantitative data, so before the decision to purchase, users can be very intuitive comparison of the various models of the air resistance and other performance. A typical wind tunnel test diagram, note that most of the wheels in the wind 10°-15° can achieve the minimum wind resistance, rather than all the direction of wind can do very low resistance.

The use of carbon fiber to make wheels or even whole sets of wheels can achieve a very high rigidity weight ratio. We all know the characteristics of the carbon fiber frame: Carbon Wheels it can be very hard and very rigid in one direction. The carbon Wheel Group is usually very rigid, which reduces the number of spokes required.

Compared with carbon frame and other parts, the carbon fiber wheel group has more stringent material requirements, the top carbon wheel will use M40 or above grade carbon fiber to uplift rigidity, and the carbon wheel is generally T800. At the same time, the carbon fiber wheel group is relatively less fussy about strength. See what happens when lightweight hits a dog ...

At the same time, because of the manufacturing method, aluminum frame in the production can not guarantee a full and unbiased pendulum, but the high quality of the carbon fiber wheel frame to achieve this, so that the spokes tension is more average, the wheel group higher quality. Therefore, carbon fiber in the wheel group is easy to pressure over aluminum alloy is also a matter of course.

This is one of the reasons why the price of the carbon fiber wheel is expensive ... Their good product rate is still not particularly high, Carbon Wheels and therefore there will be 1234 and so on.

Very light, very high aerodynamic, very high weight rigidity ratio, to the competitive performance as the main consideration, the carbon fiber wheel Group is obviously very valuable. But why, many people think the carbon fiber wheel group is too expensive?

The short board of a cask

The ultra-high-frame carbon wheel provides aerodynamic advantages, but in a complex wind environment, it can significantly affect vehicle handling. It is clear that such a wheel has a narrower range of applications. In addition, manufacturers often promise a set of wheels can reduce the amount of resistance, Carbon Wheels but the claimed value is not universal. The minimum resistance of many wheels is between 10°-15°, and once the wind blows beyond this range-for example, if you turn a corner-the air resistance may suddenly become larger, which can also cause manipulation problems. I do not doubt the authenticity of wind tunnel tests and the effectiveness of aerodynamics. But how are they going to work in the real world?

With strict control variables, researchers have built a perfect environment to measure wind resistance, in which wind speed and direction are constant, which in turn means that wind and wind changes may significantly affect the results of the measurements. In other words, Carbon Wheels the difference in air resistance between the various wheel groups is so small that they can only be measured in highly controlled environments. This data is measured on the wheel itself, without considering the status of the wheel when it is loaded into the car. Bontrager has made a top-notch TT frame (OK, checkers) and their wheels together in their research reports on wind resistance testing, and the conclusion is that wind resistance will be greatly affected by changes in wind direction. Therefore, the so-called aerodynamic advantage in reality is impossible to achieve theoretical results. This is a more idealized model.

Another advantage of carbon fiber is that it can be molded into various shapes through mold precision. With the help of Hydrodynamics model, computer simulation and real wind tunnel test, the shape of the carbon wheel can achieve the limit of the factory's ability. Publicity breaking wind and wind resistance is now the main direction of carbon marketing, and these capabilities can be sorted by quantitative data, so before the decision to purchase, users can be very intuitive comparison of the various models of the air resistance and other performance.
