Product Description


Mavic Cosmic Pro Carbon Exalith 25 Wheel

This carbon wheel offers an optimal balance of low frontal drag and crosswind stability making it a perfect upgrade for making your road bike more aero.

Crosswind stability means you can ride Mavic Cosmic Pro Carbon Exalith wheels in all conditions (unlike first-generation time-trial/triathlon bike disc wheels, which are horrible to ride in crosswinds).

What's more, the wheel's Exalith alloy brake track overcomes most carbon wheels' main shortcoming - compromised brake performance when the wheels heat up on long downhills.

Exalith Brake Track
The rim's brake track is an Mavic exclusive aluminium alloy whose brake performance is 18% more efficient than their previous best alloy rims. Another bonus is that Mavic's Exalith treatment will last for 1,000s of miles so the wheels will retain their carbon stealth black good looks. If you want the lightweight stiffness of carbon wheels without sacrificing braking performance, these wheels come highly recommended.

The best balance of low frontal drag and crosswind stability

  • 45mm deep NACA (National Advisory Committee for Aeronautics) profile reduces drag in all conditions
  • 25mm external rim width integrates perfectly with the (supplied) 25mm tyre to reduce drag and enhance crosswind control
  • Patented elliptical spokes enhance aerodynamics

Perfect efficiency and low weight

  • The 17mm (internal width) rim combined with the Mavic 700x25mm tyre (which comes supplied and ready fitted) conforms to the growing consensus that wider tyres are not just more comfortable, they're also faster. More on this.
  • The whole wheelset weighs just 1,650g (front and rear without tyres, tubes, rim tapes and QR) to make every climb faster and/or easier

Instant Drive 360 freehub mechanism
The rear wheel freehub's Instant Drive 360 ratchet drive system is mechanically simpler, lighter weight and it engages almost twice as fast as traditional pawl mechanisms.


  • These wheels are sold singly (but don't let that put you off buying the pair)
  • The rear wheel takes a Shimano/SRAM-compatible 9/10/11-speed cassette
  • The rims are 17mm wide (internal width) and 45mm high
  • Recommended tyre size: 700x25 to 700x32mm
  • Straight pull (stronger than J-bend), bladed, double butted steel spokes (16 on the front, 20 on the back)
  • Radial lacing front
  • Isopluse lacing rear - the spokes are laced radially on the drive side and 2-cross on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges.
  • Exalith treatment for optimal braking efficiency and a distinctive look
  • Braking distances are 18% shorter than average in wet or dry conditions
  • Reduced rim wear for extra longevity and a full black look that lasts for thousands of kilometers
  • SUP (Soudé Usiné Process) welding - here the rim joint is welded then milled for a smooth seamless finish to ensure the rim is absolutely true and the braking surface is judder free
  • QRM (Qualité de Roulements Mavic) double sealed cartridge bearings are very smooth-rolling, and they're user adjustable
  • Supplied fitted with made to match 127tpi Mavic Yksion Pro tyres (tube and rim tape supplied)
  • The GripLink front tyre offers confidence inspiring grip up front
  • The PowerLink rear tyre minimises rolling resistance to help convert power into speed
  • Maximum recommended pressure: 110psi
  • The wheel comes supplied with a pair of Exalith brake pads (don't use alternatives!), a quality QR, and a multitool that combines a spoke wrench suitable for bladed spokes, a QRM bearing adjuster and a tyre lever
  • Recommended maximum weight: 120kg (rider + bike)
