Less weight and lower price for a proven champion. New rim technology reduces weight, inertia and cost for the same strength and stiffness to give birth to a new Cosmic Carbon SL. Now at 1740 grams, the new SL is the best aero wheel you can get for the money.

Lower inertia and high efficiency

20 grams lighter rim thanks to a new alloy rim extrusion

12K carbon flanges for frontal and lateral stiffness

Straight pull radialy laced spokes for increased stiffness and durability

Exceptional aerodynamics

52 mm elliptic rim flanges

Low count bladed spokes

Convenience of alloy rim

Full tire compatibility

Efficient, predictable and weatherproof braking without the need for special brake pads

Strong, durable and impact resistant rim

Technologies:

FTS-L - Force Transfer System Light
The ‘FTS Nose’ is an extension of the hub body that goes inside the freewheel body. The contact zone between the pawl and the FTS Nose is reinforced by 2 stainless steel inserts, which allows for manufacturing an all aluminium, mono-piece hub body. The pawls are centered exactly in the middle of the freewheel body.

ISM - Inter Spoke Milling
Since the rim wall between each spoke hole is subjected to very little stress, it is possible to mill it to save weight. The rim is CNC machined, leaving just the necessary material to obtain the best weight/rigidity/durability ratio. A Mavic® multi-patented exclusive concept (US 6 402 256).

Maxtal
Exclusive alloy developed specifically for Mavic by Pechiney Alcan Group, for rim manufacturing and optimizing alloy characteristics vs. that specific use.

QRM+ - Qualité Roulements Mavic® Plus
Sealed cartridge bearings including a specific high precision adjustment ring. Precisely adjusted to the hub, they participate to the lateral rigidity due to an optimized positionning,

SUP - Soudé Usiné Process
After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.

UB Control - Usiné Brut Control
The sidewalls of the rim are milled with a diamond point on a digitally controlled machine after assembly and anodization
