    Carbon clinchers a step above the rest.

    Rather than use the "wider is better" design that seems to be all the rage, Shimano put the Dura-Ace 9000 C24 Carbon Road Wheelset to wind tunnel testing. The result: the 21mm front and 23mm rear rim depths, coupled with a rim width of a narrow 20.8mm were found to not only create a smoother airflow, they also increased stability in a crosswind. Additionally, compared with its closest relation, the C24 WH-7900, the C24 WH-9000 features greater rigidity and vertical compliance for a comfortable ride. While the wheels are a high modulus carbon fiber, the braking track is aluminum for reliability.

    A lightweight, aerodynamic wheel is useless if it doesn’t accelerate quickly. For this reason, Shimano ensured that the bulk of the rims’ weight is at the center. Shimano used a specifically designed bearing that is able to be pushed to the outside of the hub. The hubs also feature wide flanges for torsional and lateral rigidity, A7075 alloy axles, and a titanium freehub body. Sixteen radial-laced spokes are used on the front wheel and 20 double-cross on the rear.

    Bombproof so Far...

    • Familiarity: I've used it several times

    I bought these as a backup/training/climbing wheelset to compliment my Zipp 404 NSW's. They are very light, very stiff, and very predictable so far. They have met my expectations so far. By no means are they as fast on the flats as the Zipp's, but that's not why I bought them. They climb very well and the aluminum brake surface is predictable on steep descents. I look forward to logging the miles this fall and winter.

    Worth it, take the plunge!

    • Familiarity: I've used it once or twice and have initial impressions

    I'm so glad that I gulped and bought these wheels after reading the comments here! I can feel the improved acceleration from their lighter weight, I think I roll along faster on them, they run perfectly true out of the box, zero issues with the brake pads. Two very minor niggles: (1) I got the same 10-speed Shimano cluster that is on my other set of wheels, and the spacer provided with these wheels puts the cluster slightly further outboard, so I have to adjust the rear derailleur cable a tad when I'm switching rear wheels, and (2) I think my other wheels (black Shimano WH-R-501A's) look better - but appearance is not the goal here!
    According to Shimano's specs, the weight difference between the two wheelsets is 536g, or 1.1 lbs!! Adding 160g for folding vs wire bead 23mm Conti Gatorskins and 80g for Conti Race Light tubes vs standard ones gives me a total weight saving of 776g or 1.7lbs. And that's all at the rim, where one saves doubly: not only less mass to move down the road, but less rotating mass to accelerate (and for rotational inertia the weight at the rim multiplies by the radius of the wheel).

    Do it!

    • Familiarity: I've used it several times

    UPDATE: *** I've put about 750 miles on this wheelset and the love affair is still going strong! At first, I thought maybe it's the 'new part feel' that had me liking these wheels so much but it's long passed that. These wheels just straight up perform!*** It's the biggest upgrade that can be done to a bike. A good set of wheels changes the ride from mile one. Don't get bogged down in the online 800 wheel set on sale for 399. Those are really 400 dollar wheels marked up before being discounted. Not to say they're bad (I've owned a few sets) but wheels like these dura ace c24s are a step above. They shine all over, handling, climbing, rolling but where I find then to really excel is on those false flat (3 or 4 percent) stretches. You know, those 4 minutes efforts that leave you sucking wind. These wheels help there. They are light and roll which gives you the ability to just smash the pedals and be fine when it's over. Do it. Buy them. Don't tell your spouse and enjoy a bit of cycling nirvana all to yourself.

    Great wheels

    • Familiarity: I've used it several times

    I just upgraded to these wheels, and have noticed a big difference in climbing and speed. The one thing I like is that these wheels are also really quiet on the downhills. The wheels are stiff on the climb which has improved my times. I'm using 25mm tires on these for a more comfortable ride. After a week on these wheels I did The Death Ride 15K of climbing and these wheels where amazing.

    maybe a problem

      I purchased this wheel set tubeless clinchers and have climbed over 500,000 ft in one year with no problem however the rear wheel is now making a strange noise that no one can figure out ... three bike shops can't figure it out . it sounds like the brake pad is rubbing against rim but it's not . the wheel only makes the noise while mounted, it's silent removed and spun while holding in hands . I went on you tube and server riders are experiencing the same phenomenon . it's does not effect performance but it's driving me crazy . does anyone have same experience

      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.

      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.

      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.

      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.

      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.

      Just wondering, how loud do the hubs click on these wheels? Kind of a weird obsession of mine, I just love the sound of a really loud clicking hub.

      Does anyone know if can run 32mm wide tires on these?

      What is the downside to using tubes in the TL versions of these wheels? TLs appear to be slightly heavier .. anything else? Thanks..

      Catherine, I have been riding a set of these for 4 years. The first year or two I ran them tubeless. After a few issues with the actual tires not holding up very well, I decided to run them with tubes. They work fine with tubes. No problems at all. Also these are wonderful wheels. They are super smooth and roll and climb great. Hope that helps,

      Hey guys....I apologize if I'm beating a dead horse here but I need to confirm if these are compatible with a Shimano Ultegra 9 speed cassette.

      I have an older frame, 2009 BMC SLX01 Racemaster. Not much clearance for wide rims/tires. Are these wheels compatible? Also, I assume a spacer is included for running a 10-speed groupset? Thanks.

      I don't have a definitive answer, but 20.8 mm has been Shimano's stock rim width for at least...a decade(?), so I can't imagine that an '09 BMC wouldn't have been able to take any Shimano wheel at the time. And 20.8 mm isn't exactly "wide"; I think 19mm is the old standard. If you run into any clearance issues it'd probably be from wider tires.



      Yep, as noted in an answer to another question here, a spacer is provided.

      What are the tiny holes drilled into each side of the wheel for?

      Is there an upper rider weight recommendation for these wheels?

      Best Answer

      I have weighed 240 when I bought the C24's (Tubeless ready model) now 9,000 miles and 2 years later at 215, wheels are still going strong. I have hit many potholes and obstacles, don't want to jinx by saying b---proof. (all on Giant TCR Composite bike)

      Are these wheels compatible with Shimano Ultregra 6800

      Best Answer

      Steve, these wheels are not specific to Ultegra 6800. You can use them with any bike (as long as it can handle 700 size wheels) on any drivetrain. So the answer to your question is yes. You can use those wheels with your Shimano Ultegra 6800. (I have these wheels on my Ridley Fenix with Ultegra 6800 and Conti 4000 II 25mm tires.)

      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

      Best Answer

      Yes, just make sure the tires are 700x27c or 700x27mm. These Dura Ace wheels fit most width tires...22,23,24,25,27,28. The tire manufacturer will also specify the rim size their tires are designed for. These "standard" road bike rims are 622x15C. Most road tires fit these commonly sized wheels. Ask any LBS and they can offer more assistance if you need it. Happy riding! Don't get the spokes caught on your ears at night.

      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.

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

      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

      will these run a 10 speed and 11 speed cassette ?

      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?

      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.

      the narrative says the wheels weigh 1364g...

      the narrative says the wheels weigh 1364g and the tech specs on the right side of the page state actual weight of 1428g. what is the difference?

      I just received my Dura Ace C24s. On my scale, front weighs 593g, rear is 824g (1417 the pair WITH stock blue rim tape). The Dura Ace skewers are 61F and 67R for "actual" on-bike weight as-sold of 1545g per wheelset....NOT including your cassette/tire/tube setup.
