Thyssenkrupp Wheels

First, big fan of CF in general.Pretty amazing stuff. I was never a fan of the carbon wheels that were offered except for the SL wheels. My main reservation was construction and the somewhat ambiguous data on the companies who made them and the processes they used.

I always like the pattern on my M7s so when I saw these wheels I decided to get a set. First the company Thyssenkrupp has been around for 200years. They are a giant tech company who has consistently pushed the limit of engineering and technology. The wheels are made in Germany. Craftsmanship and attention to detail are amazing. The machined components are quite a bit more robust than the comp and the finish is impeccable. Aesthetics aside as that’s a personal perspective and no they are not my favorite looking wheel but if you want a top shelf carbon wheel, this is it.

You're just showing off your brake discs

Ha, was about to say the same.

Ed, remind me - which discs are those?

LOL actually I was weighing the setup to get an idea of total weight savings on all the dynamic pieces. Those are the Braketech CMC rotors on the front and a Sicom floater on the rear. I’m actually using Sicom front rotors when I get around to putting the wheels and waiting for Mick to get on those 64mm rear caliper brackets so I can use the P24 rear caliper.

Hahah nothing wrong with showing off some CMC Brake Tech's yeah not available in the last 10 years and never will be again. The hot new rotors from Jeff is the Stainless SBK rotors.

Heard nothing but good things about them, maybe a bit squeaky at times and if you chip them they are toast other than that any reason why ceramic carbon brakes have not gone mainstream?

Yep need to get the pads right. Tadashi (board member) has been running the Braketech CMC on his track bike for 5 years. Almost zero wear. I’m sure cost is a factor. The Sicoms are now 4500.00 and climbing. Pretty big weight reduction and it’s rotational mass. I surmise the demand would be small so unless some breakthrough in Composite mfg happens I don’t see anything in the horizon anytime soon.

I think my favorite thing about these are the bags they came in LOL

ive read, TK wants to close the rims business because of restructuring.
close! not sell.
we will see.

This rather contradicts that.

If they want to close that part of the business. Why go do all the trouble of finding Bilstein as a distributor and finally get their first order of Ducati rims in 2 weeks ago. Then again I have no clue how or companies think. Sometimes closing and showing a loss actually puts money in their pockets by showing a loss on their taxes.

considering a set of these….’20 PV4 Base.

Forthose who have actually gone carbon…

obviously I’ll notice a difference (rotating mass, unsprung mass and all that) but is it completely transformative? Is it $4k better for street duty with maybe 1 or 2 track days a year?

For 4K I’d hope it would make it feel like a completely different bike.

and I know I could get the S/R wheels for half that or less used but they’re a good deal heavier than the carbons and from those who have upgraded to the March or OZ Gass I hear a lot of “yes, it feels lighter but it’s not night vs day different”

Thyssenkrupp wheels are stronger than BST wheels. Well actually let me rephrase that. BST came out with a wheel recently that is stronger than their other carbon wheels. The carbon wheels that come with the BMW M 1000RR are Thyssenkrupp. The carbon wheels that come with the BMW S1000RR M package are not Thyssenkrupp. They are made by some other company. I believe in Slovenia or somewhere around there (not rotobox). After doing my research and speaking to my dealer rep before I applied to become a dealer ( I didnt want to sell another carbon wheel that broke like BST wheels. In 2 years I sold 17 sets of BST wheels and of those 17 customers 8 bought a replacement wheel). I found out that Thyssenkrupp is the first carbon wheel company with worldwide approval for road use. Here is a link showing every certification they have. thyssenkrupp carbon wheels: the first with worldwide approval for road use - thyssenkrupp Carbon Components

Their claim to fame is that unlike other carbon wheels that are made using layered carbon. They make their wheels using braided carbon which is what apparently gives them that extra strength. And they fill the spokes with foam for added reinforcement. Here is a short youtube link showing how the wheels are made and a another 2;30 min video

I have not. I have never ridden a Duc with stock wheels The lightest wheels I have in addition to the CF are the OZ in Magnesium which is what I used when I built the 1299 and I did run those with the CF rotors and it rode quite a bit different vs the steel rotors. I don’t expect much difference with the CF wheels although the rim section is for sure lighter and I actually got these wheels for another build.and I will be using the Sicom rotors.

I will say this is a matter of preference. I would say the bike with the CF rotors felt a bit weird until you get used to it then the steel rotors feel slow from a response perspective.

The gyroscopic factor of the heavier mass lends a bit of a stable feeling and for an all around street bike, I would stay with a good aluminum wheel and your steel rotor of choice (I use the March M7 and the TK rotors) The carbon wheel, carbon rotor is a whole different animal. If I wasn’t tinkering with tech I would not run CF wheels on a daily driver and that’s just me. If I had to run CF wheels from strictly and engineering perspective, I would use the Thyssenkrupp hands down regardless of what the wheels look like or weight.

Just for a data point, I bought my 19 v4 base last year and tracked it throughout 2020 on the oem wheels. This year, I’ve mounted a set of the Marchesini mags and my impression is just as you have heard - noticeably lighter and quicker handling, but not a “night and day” difference.

I prefer mags over carbon wheels, but I would consider a set of carbon for a track bike - not sure I’d trust them on a street bike (I recognize this might not be an empirically validated opinion).

And like Ed, I would run the TK carbons preferentially over other brands (with Dymag a close second).

Really? That’s… concerning.

Also - cool video. Would be cool to see video of their failure testing and analysis.

Honest question, you guys ride a V4S and think the wheels need to be lighter?

I feel like a knob because I'm worried about foot and hand controls since that's all I'm willing to pay for after that $29k nut to buy the thing.

Its not really that concerning. The guys that broke them all live in the NYC and Long Island area. The potholes on the Belt Parkway, Southern State Parkway and other non highway areas are horrible. Here is an example. I leased my Jaguar January 2018. My lease is up December 2021. From the time I got the car I wound up changing every single tire at least once because I would either have a blow out from hitting a pot hole. Or I would hit a pot hole once and get a bubble then some time would go by and I would hit a pothole again with that tire and have two bubbles. So I would put a another one on. I always put a used one on that had little mileage. Finally last November I didnt want to have 4 different tires through the winter so I bought 4 new all season tires. In May I hit a pothole and my left front has a bubble. I also bent my two front wheels and had them fixed. Mind you I have 18 inch wheels. As soon as I think I know where the potholes are new ones pop up. And the DOT just fills them in. They just did the entire Belt Parkway within the last month!!!!!!! Its almost the end of summer and they started in July. NYC and Long Island re-due their highways in such a manner that every July they re-due them because of the crap they use. 6 inches of old asphalt is shaved away and 6 inches of new asphalt is put on. Some parts of the Belt Parkway where they rebuilt the bridges were rebuilt have a 1/2 miles of concrete road before and after. But when they made those parts of the parkway concrete they dug down 6 feet and made different types of layers as a foundation. So those areas of the roadway are good. But many street areas have those potholes as well. Hit one at hard enough at the wrong angle and you bend or crack a wheel. I bent my OEM Ducati wheel 2 years ago. My friend crashed 6 weeks ago after he hit a pothole at night while getting on the southern state parkway. He cracked his Performance Machine wheel.

Ive gone through many thinner potholes that werent that big while white lining and Im lucky havent gone down or cracked any wheels. But I know guys who have. The 8 wheels that were changed were all do to either hitting deep potholes. Or being morons and thinking they could lift their front up before hitting the curb to get on the sidewalk at 35-40mph and show off. Instead it was too late and bam they hit the curb going too fast LOL

I have the 1299. It still has the stock wheels. Ive thought about getting the Marchesini M7RS or OZ Gass forged wheels a few times. I know the bike will handle better. So far Ive shed a decent amount of weight off the bike with the mods Ive done. Im sure the wheels would make a difference. How much lighter are forged aluminum Marchesini or OZ than the wheels on a V4S? Or do they weight the same?
