Low weight and optimized efficiency

ISM 4D rims maintain low weight while improving aerodynamics
21mm external width (17mm internal) gives improved rolling efficiency and comfort

Optimized responsiveness

Stiff and strong Zicral spokes
Isopulse lacing to the front and rear for increased wheel stability
High grip GripLink front tire
Low rolling resistance PowerLink rear tire

Exalith braking efficiency and distinctive look

Braking distances that are 18% shorter than average in wet or dry conditions
Reduced rim wear gives them extra longevity and a full black look that lasts for thousands of kilometers

GripLink

GripLink

Grip and control
A front tire, whether a clincher or a tubular, must fully liberate the wheel’s ability to hold the ground and control the bike. Therefore, GripLink tires are optimized for front use, by offering a superior grip and extra puncture protection.

Zicral

Zicral

Light, stiff and strong
A specific aluminum alloy that provides spokes with higher stiffness-to-weight ratio while being stronger.

FTS-L

FTS-L

Force Transfer System Light
Reinforcement of key transmission components: the contact area between the pawl and the hub body is reinforced by 2 stainless steel inserts, which allows the use of a 100% aluminum hub body.

Isopulse

Isopulse

Optimum energy transfer
The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges.

PowerLink

PowerLink

Low rolling resistance
A rear tire, whether a clincher or a tubular, must fully liberate the wheel’s ability to transfer power and generate speed. Therefore, PowerLink tires are optimized for rear wheel use, by minimizing the rolling resistance.

ISM 4D

ISM 4D

Inter Spoke Milling 4 Dimensions
An exclusive Mavic patented concept, ISM 4D significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance ; the right mix to make the most of any ride. The smooth profile also helps reducing aerodynamic drag

Fore

Fore

Stiffer and stronger
Instead of being drilled, the lower rim bridge is pushed up on the inside, then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intact.

Exalith 2

Exalith 2

High braking performance
The Mavic exclusive Exalith 2 technology for aluminum rims has been refined to provide a very high level of durability and braking performance in all weather conditions.

Maxtal

Maxtal

Light and strong
Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.

QRM+

QRM+

Qualité de Roulements Mavic +
Our most demanding level. Those cartridge bearings are of course double sealed with C3 internal clearance, and toped with a micro-adjustability system.

SUP

SUP

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