Carbon and aluminum, a match made in racer heaven.

Mavic’s no stranger to forging ahead with combinations of materials — the long-running Cosmic Carbone series is dedicated to this. They’re some of the best in the world at bending aluminum to their will, so why stray? The Cosmic Carbone 40C Carbon Road Wheelset is perhaps the most advanced integration of the two materials in the bike industry, and it's one of Mavic’s more carbon-heavy versions of the venerable Carbone.

There’s a skeleton in the rims, made from aluminum, called the Rim Bed Insert. It’s essentially an ultra-lightweight aluminum rim, but without a lot of the additional reinforcements you’d typically see on an all-aluminum rim. From there the carbon fiber is bonded to it for stiffness and aerodynamics, leaving the alloy bed to do the heavy lifting of air pressure resistance and consistent brake feel. You’ll still need to use carbon-specific pads with these wheels, but you won’t get that pulsing feeling, and they’ll dissipate heat much better than a typical carbon wheel.

  • Carbon/alloy structure
  • 40mm-deep rim profiles
  • Micro-adjustable bearing preload
  • Griplink/Powerlink tires and titanium skewers included

Nice...

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

Freshbikes shop ride, the hills of Arlington, VA, Tuesday night, May 13. Mavic is there with sets for riders to test. I put a set of these on. Only downside is I had to give em back after the ride. That, and -- forgetting I had these on my bike and was braking down a long hill -- I swear I smelled something burning (likely my imagination). I have a set of Ksyrium Elite S and there was a noticeable difference; the 40s were smooth and just seemed to 'roll.' I'm on a caad9 and with alloy rims I feel every nugget of love the road has to offer, but these smoothed things out nicely. And, yea, they look good.

Nice...

Mavic has a lot of info on their page about these wheels. Here's a close-up of the aluminum insert that shows the story clearly:
