Shimano Dura-Ace WH-9000-C24-CL Wheelset
If you want a 1420 gram wheelset with a tuned ride and legendary Shimano build quality, then the WH-9000 C24-CL is your wheelset. The rims on the WH-9000-C24-CL wheels feature a proprietary, in-house construction where carbon is laminated to a thin aluminum rim. You then get the best of both worlds. The carbon portion is light and stiff does an excellent job of dampening the ride while enhancing the strength of rim at the same time. The alloy braking surface is far superior to carbon and is incredibly durable. This is the "CL" version with is 90 grams lighter than the tubeless compatible WH-9000-C24-TL version so get the "TL" if you want go tubeless.
The WH-9000-C24-CL is 11-speed compatible and comes with a 1.85mm spacer so it will work with 10, 9, 8-speed and SRAM too. Other differences over the WH-7900 wheels include improved hub flanges for increased strength. Styling is a bit sharper with a new black anodized hub finish, black spokes and nipples and a glossier finish on the rim.
The hubs are based on Dura-Ace design featuring angular contact bearing and labyrinth seals, however vary a bit by offering straight pull spokes and a wider stance for the spokes. The flanges are super wide increasing the distance of the spokes between the flange creating a wider footprint for a far stronger and more stable wheel. The spokes are butted bladed spokes and the nipples are the standard Shimano black alloy variety. The front wheel is 16 hole with a radial lace, while the rear is 20 hole with a 2x lacing pattern.
In terms of how the wheels ride, we would have to say 2 words that comes to mind are fast and comfortable. Many factory wheels have a stiff ride quality because they use fewer spokes at a higher tension. Shimano builds the WH-9000-C24-CL to ride like a well-conceived hand-built wheel that smoothes rough roads white having plenty of rigidity when needed for hill sprints and criteriums. You also get a particular amount of built in durability and longevity with the hubs, because of the design - they will last many seasons with no required maintenance. They offer a pair of the best skewers in the business and over the past few years this carbon-hybrid rim design has proven to be as durable as anything else currently on the market. Includes skewers, rim tape, spoke wrenches and wheel bags.

I've had these for a few years now. They are light, spin up fast, climb very well, and I've found them to be comfortable to ride on a regular basis. I haven't had any issues with the quality of the build, although the rear wheel may be slightly out of dish. Mine have a little over 4,800 miles on them and the wear indicators are almost gone, so it will soon be time to replace them. I had hoped to get more miles out them, so that is my only disappointment with them.
Pros Light, stiff, comfy ride, super stable

My C24's came out of the box from Excel perfect and have stayed perfect for thousands of miles of riding over steep, rough, wet, gritty roads from Alaska to Vermont. I like the light weight for going up hill and I have not had to touch the bomb-proof hubs. In short, these wheels are a great ride, plus they provide great braking in the wet and on some serious downhills. I keep thinking I need to buy more expensive wheels, then I ride on my C24's and put away my credit card.
Pros light weight, ride quality, braking

Very light, great hubs, but the quality of the rims is horrible. They do not run true, side to side or vertically. I went through 2 sets of warranty rims out of the box. Bad pulsation on both front rims, non contact areas for the pads on 50 of the rim where the rim is welded on the rears as well. After installing new pads on both sets of wheels, the pads soon had chucks of metal imbedded in them, a poor sign of the rims quality. Also, the free hub body did not feel solid going over bumps. I would suggest a custom wheel build. While slightly heavier, the quality will be superior.
Pros Light, great hubs
Cons very poor quality rims
