ShimanoDura-Ace WH-R9100 C24 Wheelset(Return to Product Page)

After much research, I decided to go with these wheels since they are carbon fiber, but the braking surface is aluminum. And WBW popped with a one-day special sale so I got them for a very good price. The wheels are light and climb well. Also very good in crosswinds. I had several questions, all of which were answered promptly via customer service chat, including that I would have to readjust the hi and lo limit screws after putting my cassette on the rear wheel. I really notice the difference in these wheels over my former ones when I pedal hard, especially on rolling hills. It is at higher speeds or hard pedaling that they separate themselves from stock wheels. Getting the tires on these wheels also was fairly easy. I am very happy with my choice.

They are on my Ti road bike and replaced some 6-year old Velocity A23 pro wheels that cracked at several spoke holes on the rear wheel. I wasn't interested in deep carbon wheels but wanted something light weight. They are great but with one small problem. The rim strip on the front wheel had a little sharp point at the valve hole. This lead to several punctures at the base of the valve stem. Once I diagnosed the problem, I put some electrical tape over the area which seems to have solved the problem. In retrospect, I should have used a soldering iron to melt the offending sharp point.

Unfortunately I recently wrecked my WH-9000 C24s in a crash, but no doubt they were the best wheels I've ever owned - and I've had some good ones! Dependable, stable, fast and light... with an alloy rim surface for superior braking, I WILL own another set some day!

I was looking for a stiff and light wheel set to replace my Easton EA 90s that were breaking spokes. I wanted a reputable, known brand that could be serviced anywhere. I like to climb, so I wanted something light and stiff, not necessarily the fastest set. These Dura Ace wheels are fantastic! They make the bike seem to float uphill.

Bought a set of these babies to replace my Ksyrium Elite S. Between the super quiet free hub and the 200g weight savings, I gained 150W on my FTP.

All kidding aside, WBW hooked it up on these awesome wheels.

This is my second set of Dura Ace C24s, and I bought these on sale at Western for a second frame I'm building up. I'm a larger rider, (6,1 225 lbs) and I have never had any problems riding these-and I've now been riding C24s for a few years in all kinds of conditions. In fact, I have found them to be pretty bomb proof- I've never even had one go out of true. Their best feature is their low weight, and as a climbing wheel, my bike feels like it literally floats uphill. Though I don't race, I've set all sorts of personal best times with these both on Cycle Oregon and STP, which makes riding a lot of fun. The rims are wide enough to fit 700X28 tires though I have have been running 25s with no problems, and they look really great on my bike to boot. These wheels are tough to fault in my opinion, and especially if you're a larger rider as I am looking for a really great set of wheels, you'll never be disappointed with the C24s. Go for it!

Needed all purpose lightweight rims for my 2012 SuperSix and didnt want to break the bank on full carbon. Only about 250 miles so far but feel comfortable and responsive on climbs and speedy descents. No issues and quick install.

Have not ridden these extensively yet but they feel solid, are true and run smooth. Look really nice too. I would not pay full retail but at the sale price of less than $800 they were too good to pass up.

Bought these to replace Mavic Ksyrium Equipe. True, bad comparison. BUT, what a difference. A lot of climbing where i ride in NorCal. Wheels are light, solid and alloy braking surface. They weighed in lighter than a new set of Enve SES 3.4 DT Siwss 240s.

Very smooth and a lot more forgiving but at the same time more direct power than the Ksyrium. So much so that even i could notice it immediately. My only gripe is that for so much money, they could have had Ti skewers. Guess you need to spend thousands before you get $ Ti skewers! Would be a no brainer climbing wheel with Ti skewers. Lost a star on that. Performance 5 stars. Comes w wheel bags.

A lot of long rides. Wheels holding up very well.

I have used Dura Ace wheel sets for over 5 years now and they never disappoint!

Looking for a lightweight wheelset to use in events but not training.

Bought these on sale for an older bike with tight frame clearance. The hubs are excellent and they allow me to use 25mm tires on that older frame. Used only for 20-40 mile hilly rides. Pretty ordinary otherwise. Rims are narrow compared to the modern 23-25mm standard. Spoke count is too low for bigger or stronger riders. Modern wheel tests say aerodynamics is more important than low weight unless your ride is strictly mountain climbing at slow speed. Same tests show wider rims and tires that have lower rolling resistance and less rider fatigue contribute more than wheel weight to average speed and distance covered. For the same price, better options are available from HED, Boyd, Mavic and Bontrager. A wheelset for Shimano fanboys and weight weenies.

These wheels were the perfect upgrade. Bike is running on all cylinders:)

This is my second pair of Shimano Dura Ace wheels and they outperform and are more reliable that wheels that are a lot more expensive. I highly recommend them

While the rims arent as wide as some of the other brands on the market, the wheels are very strongdurable, yet lightweight. Hold the corners well, even when descending. And the Shimano hubs are smooth.

These are some nice, light, well-built wheels. I have them on a couple bikes and they ride very nicely and are pretty durable. Have several years on one pair and have no complaints.

The 9100 C24 wheeset is a great, lightweight, wheelset. If you're climbing plenty of hills andor just want an all around wheel, this is the wheelset to get.

The 9100 is replacing my 7900 C24 and I noticed a difference with the noise every rear freewheel hub makes. Freehub noise is a little louder than the 7900 C24, however, it is still silent when compared to most wheelsets. Drafting off another cyclist can still be done in stealth mode.

Ok, ok.

Was very excited to purchase the new wheels upgrading my 2013 Cervelo S5 (upgraded from Ultegra to Dura-Ace) from 2011 Mavic Ksyrium Elite Road Wheelset to the C24s. Pulling the wheels out of the box I was amazed at how virtually identically the rim was to my 2011 Mavics (odd). Also, no aerospokes on the C24s (another negative).

My Mavic's worked great and the wheels had no problems at all. Now and while I will caution I am a Clydesdale rider, I am getting frequent flats under very slight pavement imperfections or riding over debris on the road (gone through four tubes in the dozen or so rides on the weekend since I received the wheels). Getting snakebites every time on the tube when I have checked the pressure prior to every ride. And the latest tubes were even slimed to no avail.

The tires were brand new Continental 4000s when I received the new wheels.

Almost want to upgrade and go back in time to the Mavics.

I love this wheelset!
