Mavic Cosmic SL 65 Disc


With an aero rim shape, lighter overall weight, and easier to use Tubeless technology, this road wheel for disc brakes maximises your watts with ultra-efficient performance.

A perfect choice for fast, flat road races or windy triathlons, this wind-slicing carbon wheel features progressive aerodynamic technology and stable ride quality. The rim is engineered with a NACA profile that’s 65mm deep and 26mm wide.

Proven aero speed

  • 65mm deep/26mm wide NACA rim profile for low drag and stability in cross winds
  • Optimized for 25mm tyres
  • Flat spokes

Faster acceleration and better control

  • Reduced inertia of the lightweight rim delivers instant acceleration
  • Lighter spokes make the wheel feel snappier
  • Disc-brake specific spoke lacing, thru-axle compatible

Improved UST Road delivering speed, comfort and control

  • No tubes means less friction, improved efficiency and grip with reduced risk of punctures
  • Rim bed shape makes it easier to mount and change tyres

**Weight: 1750g


The wide, rounded shape of the Cosmic SL 65 rim was developed through countless hours in the wind-tunnel to produce the lowest possible drag without sacrificing stability in crosswinds. Refined spokes make it 80g lighter than its predecessor, the Comete Pro Carbon UST Disc. The rim bed shape makes it easier than ever to fit tubeless or tube type tyres. Mavic’s Infinity hub platform optimises the spoke lacing for efficient power transfer through highly controlled spoke tension. The Instant Drive 360 freewheel coupled with automatic bearing preload (QRM Auto) provides fast engagement, high stiffness and extra durability.

These wheels are engineered specifically for disc brakes, with an optimised spoke count and lacing. They are offered in Centre Lock only and are compatible with 12mm thru-axles that convert to quick release with included adapters.


Instant Drive 360 technology

Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.

UST tubeless technology

Traction and control. The UST concept improves traction, control and comfort whilst reducing inertia and flats

Infinity Hub Design

An ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear.

QRM Auto bearing preload technology

Qualite de Roulements Mavic Auto. Cartridge bearings are double sealed with e3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
