Have cobbles or hair-pin turns for breakfast.

The Mavic Cosmic Carbone SLE Carbon Clincher Road Wheelset takes a daily beating, and the carbon fairing gives you an aerodynamic race advantage without the weight penalty you'd incur if the entire wheel were alloy. You can easily ride cobbles or take hair-pin turns for your morning training session and roll into your next race with confidence.

Maxtal aluminum rims held together with a seamless SUP start the wheels off with excellent strength-to-weight ratios and braking abilities. The unused area of the rim between spoke holes is milled out to reduce rotational weight without taking a bite out of stiffness or durability. The brake track and rim are finished with Exalith 2 treatment, a noticeable crescent pattern through the entire milled brake track. It improves braking power and modulation while increasing the durability of the rim.

The brilliance of this type of wheel design is that the Maxtal rim takes the daily beating, but the carbon fairing gives you an aerodynamic advantage without the weight penalty you'd incur if the entire wheel were alloy. The Carbone Wheelset’s 52mm-deep fairings are finished with the same 12K weave as the SLRs and find a sweet spot between just-barely-deep-enough, and the too-deep-to-ride-in-crosswinds.

The SLE Wheelset benefits from Mavic’s improved hub design, making them more aerodynamic with flatter construction. Each hub uses double-sealed, QRM+ cartridge bearings, which are micro-adjustable. Too add stability in the rear hub, Mavic used FTS-L reinforcement between the pawl and hub body—two stainless steel inserts that add strength without much weight. Bladed, straight pull, steel spokes lace the rims to the hubs in a 16 spoke, radial pattern on the front wheel. The rear wheel uses a radial/two-cross pattern with 20 spokes for a balance of weight and strength.

The Carbone SLE Wheelset comes with BR601 front and rear quick-releases, wheel bags, Exalith brake pads, a computer magnet for the front wheel, adjustment wrench, valve extender, rim tape, and user guide.

Here's what others have to say...

could i use other brake pad like swiss green brake pad, or i only could use the Exalith brake pad? thanks

Hey there Roy, while it is an alloy rim, the coating that Mavic uses is only designed for the Exalith pads. The wheel set comes with a set for front or rear.

Solid Aero CF Wheel Option

Solid performing wheelset if you want the dependability and durability of an aluminum wheel but aero and look of a CF. The whining brake squeal of the Exalith coating is all but gone after 3 weeks of riding. Breaking performance is equal to Mavic Ksyrium Elite all aluminum wheels. The valve extenders are a bit of work to get used to, but can easily replace with a longer valve as a workaround.

I am a big Mavic fan. I have a set of Ksyrium SL that are 10 years old and still going strong and true. I also have a set of Crossmax SLR's for my mountain bike. Anyway I was looking for a new bombproof set of wheels that had excellent braking. The Cosmic Carbone SLE really peaked my interest with the black Exalith braking surface. Initially the braking surface squeals horribly and embarassingly. I bought the Jagwire brakepad toe-in tool to help with with toe in. That made all the difference. Braking is so much better than standard aluminum rims and I suspect much better than a carbon braking surface. Some downsides. The spoke nipples are internal, water can get inside the carbon faring and can be difficult to get out. Durability I suspect like most things mavic will be amazing. The weight is also fairly competitive when compared to other carbon clincher wheelsets. I am happy with the purchase and would recommend this to someone looking for a true all purpose wheelset.

Does the brake track stay black over time or does it wear down to silver eventually?

Responded on

It will stay black forever if all you do is ride in the dry. However, riding in the rain with any sort of road debris will start wearing off the Exalith coating, I bet if given another year the coating would be totally worn to silver. I probably ought to revise my review now that I have some miles on the wheels. Mavic has a hidden disclaimer about the Exalith coating and riding in wet weather saying that it will wear off and is considered normal wear and tear, but that it doesn't affect braking performance.

Does it support Shimano Ultegra 11 spds?
