What is the world’s best carbon wheel “ThyssenKrupp (TKCC)”?

Parts & Gear

Carbon wheels are a common sight in the bicycle world.
However, it is not common at all when it comes to motorcycles with engines even in the same two-wheeled vehicles.

It is the same with 4-wheeled vehicles, and even if it is for short time racing use, when it comes to carbon wheels that can withstand heavy loads and high loads for a long time on public roads, there are almost no carbon wheels that can be adopted as genuine by vehicle manufacturers and guaranteed by the manufacturers.

But by "almost never," I mean "a little bit.The world's only carbon wheel that is used as a genuine vehicle manufacturer's wheel for both 4-wheel and 2-wheelexists.
That's a ThyssenKrupp carbon wheel!
Commonly known as TKCC (ThyssenKrupp Carbon Components).

In this article, we'll take a closer look at these carbon wheels, which boast some of the best performance in the world.
It's a long story, but if you know the truth, I guarantee the scales will fall off about 10 of your eyes!

What is ThyssenKrupp in the first place?

I think almost everyone has never seen the name ThyssenKrupp or the logo before.
As it should be.Very large complex group of companiesSo it's because they don't appear in the field, such as in the personal aftermarket market.

We don't have a big sign at the track, and it's not surprising that almost no individual users know about ThyssenKrupp.

History of ThyssenKrupp

ThyssenKrupp was born in 1999 as a result of the merger of two of Germany's leading heavy industrial conglomerates: Thyssen, which was mainly engaged in iron and steel manufacturing, and Krupp, which was mainly engaged in the manufacture of heavy machinery and weapons.

The company has been making steel since before the First World War and manufacturing heavy machinery and weapons as a result, so some of the most famous weapons and historical large machine buildings were actually made by ThyssenKrupp.

Famous examples include the U-boat (practically the world's first attack submarine), the Hindenburg (airship, the largest flying machine in human history), and the 80cm train gun (the world's largest mobile artillery battery, the first of the two built was called 'Gustav' after Gustav Krupp, chairman of the Krupp Society).

ThyssenKrupp is a global conglomerate that is "capable of making such things," although it doesn't make a big deal of it as a manufacturer because it is a notorious Nazi weapon.
For example, we make motorcycles, ships, trains, helicopters, rockets, and tanks, and we also operate steel mills, power plants, and factories.Something like Kawasaki Heavy Industries.If you think it is, you're about right.

That being said, I've never heard of you at all!

As I wrote at the beginning, the name "ThyssenKrupp" has little name recognition in Japan (or in the world) in general.
That's just as well.
As a conglomerate, we have established independent divisions and brands in various fields within the group, and there are many brands whose mother company is actually ThyssenKrupp, although they are not known to the public.
It just hasn't come out as "ThyssenKrupp.

For example, the world-famous damper for 4-wheeled vehiclesBilstein (BILSTEIN)Bilstein is one of the brands under the ThyssenKrupp umbrella.

Bilstein is famous for its high performance dampers which are used in many high performance cars all over the world, right?
If you're also interested in 4-wheelers, you'll suddenly feel more familiar with them, and I'm sure you'll suddenly have a lot more faith in them.
Because Bilstein dampers are so good in performance and quality that they make people cry.
If you like 4-wheelers and don't know it, you're a mogul.

ThyssenKrupp's Carbon Division

ThyssenKrupp Carbon Components is the group company that handles the carbon products of ThyssenKrupp.
Commonly known as "TKCC

Established in 2012 as a company involved in all aspects of carbon products, the company develops carbon springs, carbon stabilizers and other products.

The TKCC Carbon Wheels are the ultimate carbon wheels that TKCC has created by putting all of their know-how into it!
The confidence in carbon wheels can be seen from the fact that the company name has been made a brand name as it is, without setting up an independent brand like "Bilstein".

History of carbon motorcycle wheels

Carbon wheels are a rarity even today, but carbon wheels themselves have been around for a long time.

It is lightweight, high strength, high rigidity, and can even be made flexible. ......
Carbon is a dream material for wheels.

The superiority of carbon as a material can be proven by the fact that the chassis of F1, the pinnacle of 4-wheel racing, was instantly replaced by carbon monocoque from aluminum monocoque.
It's no wonder, since it surpasses metal materials in every performance.

However, it took some time to apply such an ideal material as carbon to the wheel.
The first F1 chassis to use a carbon monocoque was the McLaren MP4 in 1981 (followed a few days later by the Lotus 88), butThe wheel is very severe, unlike other placesThe reason for this is that there are many conditions that make it difficult to achieve a performance that surpasses existing metal materials in terms of overall performance.

Trauma in 1984.

Carbon wheels for motorcycles were first introduced to the public in the spring of 1984.

This was because carbon wheels were used on Honda's 1984 works machine, the NSR500, which was the latest works machine developed for the previous year's World Grand Prix 500cc class champion (the world's highest class equivalent to the predecessor of today's MotoGP).

The carbon wheels were introduced with much fanfare as wheels with overwhelming performance that surpassed previous wheels, but to their surprise, the wheels cracked and crashed in the first race.

ThisCarbon wheel cracked and crashedThe worst impression of a carbon wheel is very strong among bikers and racers, and the image that carbon wheels break and carbon wheels are dangerous seems to have been established worldwide.

Various brands have appeared on the market...

After that, carbon wheels became a hot topic again and again and were released by various brands.
However, none of the brands have been able to break the stronghold of the existing wheels.

The most advanced brands of the time such as Marchesini, MARVIC, CAMPAGNOLO, and nowadays, Galespeed, OZ Racing, BITO Magtan, Exact, and other famous brands are selling forged aluminum and magnesium wheels. Forged aluminum and magnesium wheels are much more common.

In addition, the aforementioned Honda works machine crashed due to a broken wheel, and as a result of this, it was recognized by race officials that carbon wheels were dangerous, and as a result, carbon wheels were banned from use in major races around the world.
There are some international races where it is OK to use them, depending on the race organizing body, but in MotoGP, the most well-known race, it is prohibited.

When it comes to customizing bikes, there is a strong image that "what is used in the highest level of racing = what is the highest performance in the world", so a negative perception has been established that "carbon wheels, which are banned even in MotoGP, are only light and dangerous".
There are still carbon wheels on the market from several companies, but they have not become major players in any way.
His image was too bad when he first came on the scene, and it's probably still tugging at his tail.

The above is a brief history of carbon wheels.

About the carbon manufacturing process

It is well known that there are various types and manufacturing methods of carbon in a word.
In particular, it has become very well known that there are "wet carbon" and "dry carbon".
It is now common knowledge that any product that focuses on performance and not just appearance is manufactured using a process called dry carbon.
It's a fact that those who know at least a little bit about it absolutely know.

However, the manufacturing method is not the only one.
Even if it is the same dry carbon, there is a great variety of carbon fiber layering methods (in extreme cases, there are carbon products without fiber layering).There is a big difference in performance depending on the manufacturing method.

In this context, ThyssenKrupp's carbon wheels are the world's onlyblading carbonWe use a manufacturing method called the "Mere Old Man".
This is the process of weaving a single carbon fiber to form the rim in one piece, which always occurs in other carbon wheels.No carbon fiber seams
As the best and wheels currently conceivable.The world's only manufacturing methodWe have adopted the

The same process is used in the carbon pillars of the Lexus LFA, but they are at most 10cm in diameter.
ThyssenKrupp is the only company in the world that can manufacture such large parts as wheels with a diameter of over 17 inches.

The reason why other companies can't do this is because in order to seamlessly weave the rim of a large diameter wheel, a 9 diameter.This is because there is no other manufacturer in the world that can afford such a large piece of equipment (which of course is eye-poppingly expensive).

Carbon braiding machines are spreading all over the world, but of course ThyssenKrupp's braiding machines are the largest in the world.
ThyssenKrupp, fear not!

Are carbon wheels dangerous?

Now, what do most people think of carbon wheels?

  • Light but cracks
  • It doesn't bend like aluminum, so when it breaks, the air goes out at once.
  • Missing rim due to tire replacement, etc.
  • Strong, but lacks rigidity as it does not have the rigidity of metal and "bends".
  • It is dangerous at the limit range because it returns all at once like a spring when the wheel returns.

I think it looks something like this: ......

These images are the very reasons why carbon wheels were banned at the time they were banned, and certainly the carbon wheels of the time had those characteristics.
This is dangerous and it is only natural that it be banned.

The history of carbon wheels is the history of the search for how to eliminate these negative elements and create a wheel that is lighter and higher performance than existing materials while ensuring safety that surpasses existing materials. The history of carbon wheels is also a history of the continuous search for ways to make wheels that are lighter and more efficient than existing materials while ensuring safety that surpasses existing materials.

But that was in the past, before the introduction of ThyssenKrupp carbon wheels.
ThyssenKrupp carbon wheels are designed for suchGroundbreaking on a level that defies existing conceptsThere is nothing like it in terms of material, manufacturing method, and quality.
(More on this a little later.)

For aluminum wheels

As you can see from the fact that aluminum wheels are adopted as genuine by vehicle manufacturers, it is possible to achieve strength, durability, and light weight at a relatively low price.

The material, aluminum alloy, is a very stable material, and strength degradation over time is almost negligible.
For this reason, it is often possible to use old wheels that are decades old, as long as they are made of aluminum.
(Some types of aluminum are more corrosive than others, but they're not usually used for wheels.

In many cases, whether casting or forging, it is basically more difficult to break than magnesium, and when a large force is applied, it is difficult to break suddenly even if it deforms greatly.
In fact, there are almost no stories of cracks due to impact from the road surface while driving, unless you hit somewhere in an accident.

Heavy when compared to other materialsI don't see any drawbacks other than that.
Although it is heavy, it is lighter than steel rims and spoked wheels, so it is a mainstream material today.

For magnesium wheels

This is a material that is never used by manufacturers.
(There are wheels that claim to be made of magnesium, such as Honda's Magtek, but the wheels used on public roads are made of aluminum alloy with a high magnesium content, and are completely different from real magnesium wheels.

The reason manufacturers don't adopt magnesium is that magnesium isExtremely corrosiveBecause it is a material.
The characteristic of magnesium that corrosion progresses to the inside of invisible difference material by reacting with moisture in the air is a big problem.

However, internal corrosion is still an unavoidable characteristic of the material.
It is also more susceptible to impacts and loads than aluminum.fragileCharacteristics.

However, if the car is to be used on public roads for a long period of time, the manufacturer cannot brand it as "roadworthy".
If you know the characteristics of the material, you'll understand that it's true.
the long and short of it is thatunreliableof.

However, it is not that simple and there are more problems than you can imagine.Pretty risky material.You should be well aware of this fact.
It wouldn't be a problem if it was a part that wasn't subject to stress, like an engine cover. ......

For conventional carbon wheels

The manufacturing technology of carbon, which can be called a new material, has evolved greatly since the 1980s, and the carbon wheels on the market today are different from the bad carbon wheels of long ago.

The performance of the resin that solidifies the fibers is extremely important for carbon (not just for wheels), but as a result of the dramatic improvement in the performance of this resin, carbon skeletons are now being used as strength components in aircraft, including large passenger planes and fighter jets.
It is not just an outer plate for rectification, but is used as a stress material to support the strength of the aircraft, which is proof of its high performance and reliability.

In terms of strength, durability, weatherability and light weight, it is now the best in the business.
There is clearly no inferiority in performance to metal materials.
Weaknesses.expensiveThat's about it.

Unfortunately, even today, the use of carbon wheels in racing is often banned, and the prehistoric interpretation that "it's dangerous to use carbon wheels in racing because they break" is still prevalent.
In fact, if an impact is applied to a carbon wheel to the extent that it breaks, it is certain that a wheel made of existing material will also break, and in fact carbon wheels have the advantage in terms of resistance to breakage.

Features of ThyssenKrupp carbon wheels

Even existing carbon wheels prior to the advent of ThyssenKrupp have outperformed aluminum and magnesium wheels, as mentioned above.
There is no such thing as a seriously made carbon wheel that is inferior to metal in performance.

In addition to that.Emphasis on safety to the point of extremesThyssenKrupp's carbon wheels are characterized by a high level of strength and durability.

It's easy to get caught up in the light weight, but it's only light as a result, and weight reduction is not a priority.
The only absolute requirement is that the safety of the wheel exceeds that of existing wheels, and there is no compromise of any kind for the sake of sensational catalog specifications.

What exactly makes it different from existing carbon wheels?
The details are explained below.


As I've written many times, ThyssenKrupp's top priority is this.
All the performance is achieved under the safety, and it is close to 'if we overcome the weakness of the existing lightweight wheel, the material became carbon'.

  • Light but cracks
  • It doesn't bend like aluminum, so when it breaks, the air goes out at once.
  • Missing rim due to tire replacement, etc.
  • Strong, but lacks rigidity as it does not have the rigidity of metal and "bends".
  • It is dangerous at the limit range because it returns all at once like a spring when the wheel returns.

If you have this kind of image, you need to change your perception.


First of all, please understand that the characteristic of carbon is that it does not crack easily.
It is a material that flexes when a heavy load is applied, so it will not break in a small amount.

If the same test is conducted, the magnesium wheel will crack first, then the aluminum wheel.
as a matter of factCarbon wheels are the most resistant to crackingIt is.

Furthermore, ThyssenKrupp wheels differ from other carbon wheels after cracking.
Carbon is the most difficult material to crack, but in contrast to other companies' products that crack at the end, ThyssenKrupp's carbon wheels crack as they deform.
Even if it is the same carbon, the manufacturing process is different from other companies.I can't crack it all at once.of.

Plus! Even in a cracked state, the fibers do not break, so it has some strength and does not shatter into pieces when broken.
Even if you bend it until it snaps completely, it won't shred or shatter.It can be deformed like an aluminum wheel and keep the shape of the wheel. ......
It's only made by ThyssenKrupp.

It doesn't bend, but it bends.

One of the aluminum wheel safety myths is that if there is an unexpected impact, it will only cause bending and will not lead to an immediate fall.
That's actually true, and it's an advantage over magnesium, which cracks more easily than aluminum.

However, ThyssenKrupp carbon wheels are so strong and stiff that they won't bend under the same impact that aluminum wheels bend or magnesium wheels crack.
It's not "all you have to do is turn.It doesn't bend in the first place.I'm not sure.
By the time the ThyssenKrupp carbon wheel bends, the body will be broken, so the wheel is no longer necessary.

Also, even if the wheel were to be deformed by some accident (which is unlikely), carbon has a strong characteristic of returning to its original state even after deformation, so it can return to its original state even in areas where a metal wheel would remain deformed.
"Carbon doesn't bend like aluminum, so when it cracks, all the air goes out at once," etc.Don't be an old-fashioned stereotype.

If ThyssenKrupp wheels are bent and cracked and leaking air, aluminum and magnesium wheels are shattered or deformed.
No longer a metal wheel.It's one level different.of.

Changing a tire doesn't chip the rim.

As you probably know by now, carbon wheels are stronger and stiffer than metal wheels.
At the edge of the rim, of course.

The ThyssenKrupp wheel is a normalYou can use the tire changer exactly as you would an aluminum wheel.
Just because it's a carbon wheel doesn't mean you need to pay any special attention to it.
It can be handled exactly the same as a normal aluminum wheel.
If you don't want to get scratches from changing a tire, just use the same caution you would with a magnesium wheel.

In any case, it is impossible for ThyssenKrupp to say that carbon wheels are prone to chipping rims.
This is evidenced by the fact that the first wheels we completed are still being used in races and the rims have not cracked or chipped even after hundreds of tire changes already.

No flexing or lack of rigidity

One of the characteristics of carbon wheels is that they "flex".
However, it isAn area that would crack if it were a metal wheel.story.
This is another dimension that is one level different from metal wheels.

Metal = hard = rigid
Carbon = resin = flexing = no rigidity
If you have this classic image of a carbon wheel in your mind, throw it away now.

As you can see from the carbon monocoque chassis of F1, carbon can provide much higher rigidity than metal depending on its shape (or design).
Contrary to the image that comes from the appearance and weight, it is actually stiff and super rigid.
They don't wriggle under the loads they are subjected to while driving, or to be more precise, they deform less than metal wheels.

At the same time, it does not rock back and forth like a spring.
Because, in the first place.unyieldingFrom.

Personally, I'm not sure how you can experience wheel flex or springback when there is a super pliable material called a tire at the end of the wheel. That's one of the questions I have.
I can't help but feel that mere speculation based on the appearance of the image is just taking on a life of its own.

Dealing with electrical corrosion

One of the characteristics of carbon wheels is that not all of them are made of carbon, but the hubs are made of aluminum.

The hub can also be made of carbon, but since it is located near the center of rotation, it is less meaningful in reducing the gyroscopic effect, and since it is fitted with bearings, etc., it requires strength, rigidity, and precision.
In addition, the hub shape is different for each car model, but if you try to mold this in one piece with carbon, you will need a special mold for each car model, so it is not realistic.
For this reason, not only the carbon wheels made by ThyssenKrupp but also all the carbon wheels on the market today use machined aluminum hubs.

The problem is that carbon is conductive, and when combined with aluminum parts, corrosion called "electric corrosion" will occur.

Electrical corrosion can also occur on aluminum wheels and magnesium wheels, but it is not as big a problem on aluminum wheels.
(Difficult to say, because there is little potential difference between different materials)
This is a problem with magnesium wheels, but they have a short service life to begin with, so the wheel itself will reach the end of its life before corrosion occurs.

What about carbon wheels?
The service life of the carbon part is not as short as that of magnesium, and carbon does not corrode, so simply combining them as they are will certainly cause corrosion of the aluminum part.

This is especially a problem when the carbon is integrated with aluminum, and the corrosion that occurs in the aluminum may cause the parts that should be firmly fixed to the carbon to separate.

In the case of ThyssenKrupp, a variety of technologies have been introduced to prevent this electrical corrosion.
Unfortunately, it hasn't been published, so no details are available at .......

ThyssenKrupp wheels are designed to withstand long periods of use, up to 10 years or more, whereas most carbon wheels do not take into account the possibility of electrical corrosion.
It's been less than 10 years since they were introduced, so who knows what they'll actually look like in 10 years, but at least the wheels that were produced in the early days and used heavily in racing are still in use after several years.

To begin with.World class racing wheels for years to come.There has never been a story like this.
In the racing world, racing wheels are managed by mileage, not by years of use, while ordinary magnesium wheels have a few thousand kilometers, even though the price is .......
ThyssenKrupp, fear not!

I don't know the details of the anti-corrosion technology, but I can confirm that structural adhesive is used to join the wheel to the hub, which is slightly visible through the gap in the join.
Although some people may not like the idea of using adhesives, it is one of the bonding methods that has been used for decades as a strength component.
It is such a major material that nowadays, adhesives are used instead of welding on the bodies of ordinary commercial cars.

And it's not just gluing, it's also ThyssenKrupp's unique know-how that ensures that it meshes tightly and never separates.

heat-resisting property

The heat resistance of the wheel is very important for 4-wheeled vehicles, although it is not so conscious for motorcycles.

In particular, recent high-performance cars use ceramic rotors, which are extremely hot compared to cast iron discs.
Since there are objects that reach several hundred degrees Celsius in close proximity (some of them are in contact with the wheel), even if there is no problem with metal materials, carbon wheels made of carbon fiber hardened with resin are in big trouble.

Naturally, when 4-wheel manufacturers test wheels, there is a test for this heat resistance, and they apply a large load under extremely high temperatures to confirm that there is no loss of performance.
This is a hard test, but no existing carbon wheel has ever passed the test ......!
With the sole exception of the ThyssenKrupp carbon wheels!

Since this is a vehicle manufacturer's test, they didn't tell us the standard values and other details, but they said that the test items include changes in deformation and rigidity under high temperature and heavy load, as well as changes in rigidity and deformation when the vehicle is cooled down.

Although it doesn't get that hot on the bike, it's good to have reliability against heat generation, right?
The only carbon wheel that can break through the hard test of four wheelsThyssenKrupp carbon wheels are made in exactly the same way as ThyssenKrupp carbon wheels, so no matter how hard they are braked, they will not deteriorate due to heat.

Brading Carbon Method

As already mentioned several times in the article, in generating a cylindrical carbon product like a rimThere's no better way to make it.

This is the only method that can theoretically achieve the strongest possible strength, as the carbon fiber forms the shape of the rim without any interruption.
In addition, the density of the weave can be continuously changed without interrupting the carbon fiber, so the rigidity can be freely controlled depending on the location of the rim without changing the integral molding.

The fact that there are no interruptions in the carbon fiber, and that the braiding density and direction can be continuously changed, is absolutely impossible to achieve with existing carbon manufacturing methods.
The world's only and best manufacturing method that only a blading machine can realize.This means that when the wheel is finished, it has a performance that is definitely different from other carbon wheels.

I've got the basics down.

The inside of the rim is processed to prevent slippage between the rim and the tire, preventing the tire from slipping under high torque and causing wheel imbalance.

The inside of the spokes are filled with foam material to prevent resonance and resonance.
Perhaps they also control the spoke stiffness.

The joint between the spoke and the rim is strengthened from the rim side, and the opening is brought to the hub side to control the rigidity of the rim.
This is the part of the wheel that is typical of the latest design wheels, as it is in line with the latest trends.

The machined aluminum hubs that are inserted into the wheels also have an even surface anodizing and perfect machined end face treatment (in some places there are pin angles that are not daringly chamfered).
The material of the machined aluminum parts is A6082, not the famous but inexpensive duralumin (A2017) or the easily corroded super duralumin (A7075).

Car model specific designSo you can use the stock sprocket carrier and hub damper for peace of mind.
Throttle ON after wheel change/The fact that the shock at OFF does not change will be a blessing in the real world.

All the basic performance of the wheel has been taken care of, and there are no faulty parts.
A thick clear coat layer with UV protection is too basic to even be included in the manufacturer's advertising claims.

Proof of safety

Of course, the safety standards of each country have been surpassed with plenty of time to spare.
especiallyThe ThyssenKrupp wheels sold on Webike are approved by JWL as Japan's original specification.
Not only can it be used legally on public roads, but it can also pass vehicle inspections without modification.

There are many safety standards around the world, JWL (Japan), DOT (USA), ABE (Europe), and the only carbon wheel that has acquired all of these standards is currently made by ThyssenKrupp!
While JWL is a self-assessment by the manufacturer, in other countries tests are conducted by public organizations, so the reliability of safety is unsurpassed.

We have nothing to do with breaking safety standards all over the world, but we also have our own safety standards for ThyssenKrupp.
What it is: .......
What's more, there is an IC chip embedded inside the wheel that holds individual data on the manufacturing process and values.
When, where, and which process work was performed?
What was the numerical value of each check item at the completion of the process?
All of these things are recorded in each wheel, and the built-in data even contains image data of x-ray photographs taken during the manufacturing process (!). In the built-in data, there is even the image data of the x-ray photo taken during the manufacturing process (!).

We're really doing things that are possible with modern technology, things that no one else is doing.
There is probably no other wheel manufacturer that does this much.

Examples of adoption by vehicle manufacturers

Because we have pursued safety to such an extent, the ThyssenKrupp carbon wheel is the only genuine optional part from a vehicle manufacturer to be used for the first time in the world.
That's Porsche for you!

This is a genuine option for a brand that sells high performance, and for a car that demands extreme performance, the top-of-the-line 911 Turbo S, which is also an Exclusive.
Of course, this is the world's first genuine use of carbon wheels.
It is a feat that has surpassed the rigorous testing that Porsche can give the go-ahead for genuine adoption.

At about the same time, BMW's HP4 (high-performance version of the S1000RR, the world's first carbon frame model) also uses ThyssenKrupp carbon wheels!
This is also the first time in the world that a carbon wheel has been used as a genuine manufacturer's wheel.

The vehicle manufacturer couldn't get the go-ahead to adopt magnesium wheels, butWith carbon wheels from ThyssenKrupp, you can guarantee safety.This is proof that you have decided to do so.

It hasn't made much of a fuss, but this is actually a bit of a case, isn't it?
Used in the world's most prestigious races.A wheel that is lighter than a magnesium wheel is equivalent to proving it is safer than that magnesium wheel.Because of that.

one and only

There are still many carbon wheel brands out there and there will be more to come.
But a wheel as safe as a ThyssenKrupp, as precise as a ThyssenKrupp, as high quality as a ThyssenKrupp and as light as a ThyssenKrupp is a bit of a leap of faith.
Especially important is safety, which is a non-negotiable part of motorcycling.
This part of the ThyssenKrupp is overwhelming.

And on top of that, it's so light!
No wonder BMW and Porsche adopted it as a genuine product.

If people who are familiar with manufacturing, such as technical engineers and people involved in machine design, see the actual product, they are sure to understand that all the points to be concerned about have been perfectly addressed.
There is no part of, "This is how it's built, but is it reliable? There is no part of "Is this reliable?

Carbon wheels are the future

To be frank, I don't think there are any existing wheels that can compete with TKCC.
It does not matter what material the wheel is made of.
The highest performance of all wheels, old and new.I think it's safe to say that

There is no such thing as not the best performance ...... because it is not used in motoGP.
That's just a matter of convenience for the race organizers.

In fact, there are some tuners who are taking notice of this high performance: ....... Oops, I can't say much more yet, but stay tuned for future developments!
