King of the mountains.

The carbon clincher. For much of its short life, the design has been plagued by ailments ranging from the annoying to the downright terrifying. However, this isn't to say that it's still languishing in a limbo of inadequacy. With the Shimano Dura-Ace 9000 C24 Carbon Clincher Wheelset, it seems like Shimano somehow got hold of your carbon wishlist and checked off all of the boxes. The C24 features Shimano's widest profile ever, its strongest aerodynamic advantage, and an unparalleled responsiveness. Even more impressively, the C24 provides all of this at a weight under that of Zipp's 202 Firecrest Carbon Clincher.

Shimano's Dura-Ace 9000 C24 wheelset epitomizes the illustrious reputation of the Dura-Ace title. In fact, for the first time, Shimano has fully committed itself to achieving a superior level of aerodynamic advantage. As a result, the C24 was engineered in accordance with the newly developed Blade and Accelerating SPEED concepts. After extensive wind tunnel research, both of these development platforms gave way to Shimano's most aerodynamic wheel profile. The designs are hinged on the front and rear wheel having two different depths -- 21mm at the front and 23mm at the rear. This creates an even smoother airflow then varied front and rear rim depths. Additionally, when coupled with the 20.8mm rim width, the wheels promote an increased stability in crosswinds, as well as higher levels of lateral rigidity and vertical compliance when compared to the WH-7900 C24.

With the C24 , the weight of the wheels is centered at the hubs. This means that the rim weight is reduced, and thus the rotational weight is decreased. The beneficial results are staggering. Coupled with the aerodynamic 21/23mm rim depth, you have a wheelset that gets up to speed faster, and requires less rider effort to pin it and hold it. The centering is made possible by a clever Shimano design that's principled in the use of Shimano's angular contact bearings. The bearings' shape allows them to be pushed as far outboard as possible. This makes the hub a wider platform for the spokes to stand on, and accordingly, it makes the wheels capable of higher spoke tensions for a more compliant ride quality. Most importantly, though, the C24 features Shimano's widest hub flanges ever. The wider distance between flanges drastically increases torsional and lateral rigidity -- think about the difference between someone pushing you with your feet together, and then again with your feet shoulder-width apart. Simply put, this design guarantees an effective power transfer so that your wheels put out as much as you're putting in.

For the build, Shimano incorporated 16 radial-laced spokes on the front wheel, and 20 two-cross spokes. For even further efficiency, the C24 wheelset uses ultra-stiff, oversized A7075 alloy axles, and a quick-engaging titanium freehub body. Every wheel is 100% hand-built, and features Shimano's own high modulus carbon fiber composite. For braking, the wheels feature an aluminum brake track for a predictable stopping power that won't overheat the rim. Altogether, each component of the wheel has been designed as a symbiotic system for the ultimate in aerodynamics, efficiency, and pure speed.

The Shimano Dura-Ace 9000 C24 Carbon Clincher Wheelset is available in the color Black and with a Shimano compatible freehub body. The wheelset tips the scales around 1364 grams, and is compatible with the new Dura-Ace 9000 11-speed shift system.

Great Wheelset with one caveat.

  • Familiarity:I've put it through the wringer

Purchased these as a climbing set of wheels and they have not disappointed in that regard. Light and stay true. However, the braking surface of the front rim has a slight high spot. This could not be trued out. A little internet digging uncovered that fact that this is rather common. It causes the wheel to grab and pulse when braking. I managed to solve the problem by going to the Reynolds Cryo Blue brake pads that they require for their own carbon rims. This works a treat. The pulsing is gone at a slight sacrifice to braking efficiency.

Unanswered Question

I've been riding these wheels since last Spring and they are flawless. I love them, and keep them under my pillow at night. I just rec'd the Vittoria Open Pave EVO CG III, 27 mm tires and want to confirm that I can run them on these rims? Thanks

Great wheels

  • Familiarity:I've put it through the wringer

Got em for training. Now after putting the first 1000 on em, I'm very seriously considering another set just for Hillier road races .. They ride smooth. Very responsive. Great power transfer!! Haven't even gone a hair out of true.

Does anyone know what type of brake pad should be used with these wheels? Since they are carbon fiber with aluminum braking surface I don't know if a carbon specific pad should be used or if regular rubber pads are acceptable? I've not been able to find an answer on the Shimano site.

Aluminum brake pads. I have been running these wheels with Swissstop green pads for over a year. Love 'em.

Can these be converted to tubeless? Is that a good idea? What width tires is recommended? Is 25 mm OK, good?

Best Answer

You could, but Shimano makes a tubeless version of this wheel:

SHIMANO DURA-ACE WH-9000-C24-TL



If you want to run tubeless, you should be considering this wheelset instead.

I run the C24-TL and have for the last couple of years. The first 2 or 3 months the rims with Hutchinson Atom tubeless were great. BUT, almost impossible to get on. Broken tyre levers and fingernails by the side of the road. A couple of thousand kms later and a couple of flats - the very slow leaks started. Then the world of pain exploring how to make tubeless not leak. Stopping short of injecting goo, I opted for trusty GP4000s on these TLs ( tight to get on but ok ). Great ride, great rims, but go for the non-tubeless ordinary C24 rims.

I run Schwalbe HS One Tubless tires on this wheelset. They work great and go on easily if you learn to put the tire bead in the depressed center rim track and work the tire on by hand. No tools needed. Takes a little practice, but once you get used to the technique, Tubeless tires go on easily.

Is There A Rider Weight Limit Specified on the dura ace c24 wheelset

Love these wheels - great all around!

  • Familiarity:I've put it through the wringer

Love these wheels for climbing and all around performance. They spin up quickly, given the weight at the hubs vs the rims. Makes a huge difference on a 13,000 ft climbing day. They also perform exceptionally well on the flats and provide a ton of confidence descending. Perfect balance of compliance and stiffness with bomb-proof build.

will these run a 10 speed and 11 speed cassette ?

Best Answer

It is set up with an 11 speed freehub, but these are compatible to run 10 speeds with a spacer behind the cassette

What is the warranty on the Shimano Dura-Ace WH-9000 C24 CL ?

Hey Rvk,

Shimano offers a 3 year warranty on these wheels from the date of purchase.

I've just ordered these and now a buddy is telling me that Shimano advises that you should not use a tire lever with them as it could bend the rim. Is that true??



Also, btw-- there is a type in your description above. You have: "This creates an even smoother airflow then varied front and rear rim depths." Should be "... than varied front and rear..."

Best Answer

Hi, I took a look at the Shimano Dealer's Manual for Road Wheelsets, and found the following on page 29, in the section titled "Installing and removing tubeless tires."



"The tires should always be installed and removed by hand. Never use tools such as tire levers, as they can damage the seal between the tires and the rims and cause air to leak out from the tires."



I think this direction is specific to the installation of tubeless tires, and is concerned more over damaging the tubeless bead on the tire than the rim. Additionally, Shimano makes a tubeless-ready version of the c24 wheels, but this one is not, so the advice on tubeless tires does not apply.



I did not find any other reference to tire levers in the manual. Within reason, you should be fine to use a lever or two when installing or removing conventional non-tubeless tires.

It may be a silly question, but I am new to road cycling. I have a good bike, carbon fiber Scott, full Shimano Ultegra. Would these wheels be a compatible upgrade?

This wheels would be an excellent upgrade and they will work on that bike as well. Give me a shout and I would love to help you out with an order.

Are there any "issues" using 25 mm tires...

Are there any "issues" using 25 mm tires on these wheels? I recently switched to 25 mm tires and would like to use them on these. Thank you.

Best Answer

You should have no issues running 25mm tires on these wheels.

25mm is the way to go. I use a Scwalbe Marathon Plus 25mm on the back C24 for not flatting out, and a Michelin Pro Service Course 4 25mm on the front.

I am running 25mm Continental 4000 S and they can be mounted by hand. Nice ride!

I am running 28 mm Continental Gatorskin Hardshell with no problems, have done so for about 500 miles.

Wonderful Wheelset

  • Familiarity:I've put it through the wringer

I have been riding a set of these for about 2000 miles. I should have written a review sooner. From my first mile on these I was very impressed. Having shopped around and looked at some expensive wheelsets, one of the local shops recommended these. This was my first set of high end wheels and the performance and feel is outstanding. The Shimano hubs are so smooth. Here in the mountains of Utah, cross winds can have a big affect on handling. These handle very well on long downhills. I did run these the first season as tubeless. They worked well on that set up, but after a number of bad tubeless tire quality issues, I decided to go back to a tube set up. Either way, these are fantastic wheels and a great value.

Does this Shimano Dura-Ace 9000 C24 Carbon Road Wheelset (Clincher) come with the wheel bags?

My set just arrived from Competitivecyclist and the non-padded Shimano wheel bags were included. Liking these wheels so far!

Mine also came with Shimano non padded bags.

Hi, I have a set of WH-9000 C24 wheels...

Hi, I have a set of WH-9000 C24 wheels that are now 9 months old and noticed that the lacquer is peeling on the rim. You can scratch it off using your finger nail. You can also see blisters in the lacquer the size of a pin head. Has anybody else observed this issue? Comments will be appreciated. Thanks Clive

Best Answer

Shimano will exchange your flawed wheels for a new set (that they say will not have this problem). This can be done through your LBS.

Fantastic wheels

  • Familiarity:I've put it through the wringer

I've had these wheels for a few months now and put several hundred miles on them. They are super light, stiff, well made, the hubs are top-notch, and paired with the Open Corsa CX tires they are the best wheel I have ever ridden. I climb/descend for a majority of my riding and the aluminum braking surface was important to me, and performs excellent. Highly recommend.

C-24 Clincher Wheel Set

  • Familiarity:I've used it several times

I bought these to save my Zipp 202's for races. The only advantage my 202 Tubulars have over these is on a high speed decent. Zipps handle cross winds much better. These obviously brake better with a aluminum brake track. They are much stiffer and corner better, climbing I can not see any difference. May not be scientific, but these feel firmer and safer.

i have campy record electronic 11 speed...

i have campy record electronic 11 speed on my bike can i buy these wheels and find a campy spec cassette that will work?

I have read that Shimano and Campy 11-speed cassettes and chains are interchangeable; this means you could buy a wheel with a Shimano freehub, install a 11-speed Shimano cassette and use it with a Campy drivetrain.
