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 radialtwo 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, va...
