Mavic Ksyrium Pro SL 25c 2016 Rear Wheel

Product Code: 145384

The legacy wheel of the Ksyrium Family now gets ISM 4D rims to make it even faster and with a stepped up finish quality

The Ksyrium Pro SL is the result of over 15 years’ wheel development.

Breaking the mould
When it was first introduced in 1999, Ksyrium totally broke the mould of wheel build (traditionally 32 thin steel spokes with tiny nipples, traditional drilling and lacing). It drastically improved the ride quality of a wheel and a new generation of wheel system was born that would set the industry benchmark in the 21st century.

The secret? Finding the sweet spot for wheel performance as it became lighter, stiffer, more comfortable and at the same time more reliable than ever. The key technological developments that enabled this became character traits that still define Ksyrium today:

Revolutionary Fore drilling
Probably the greatest Ksyrium innovation is the revolutionary spoke-rim interface, taken directly from the aeronautics industry, called Fore drilling. Here the rim isn’t actually drilled. Instead its lower bridge is heated, then pushed on the inside forming a channel on which a thread is formed. The nipples (integrated into the spoke) are then directly threaded on the rim. The thread is much larger and deeper than on a traditional steel spoke and nipple, creating the strongest possible connection between the rim and the spoke.

And because the upper bridge of the rim remains intact (no drilling) the stiffness of the rim increases by about 20% without creating the weak point generated by traditional drilling. On top of that, no rim tape is needed, saving another 40g on the wheelset at the most important point of the bike

Zicral alloy spokes
Ksyrium Pro SL also uses super aero and light Zicral alloy spokes that are stiffer, stronger and lighter than the stainless steel versions used on all bicycle wheels since the end of the 19th century.

Isopulse lacing pattern
It was commonly accepted that spokes needed to be crossed at least on the drive side to spread pedalling torque. We went against this belief and created the Isopulse lacing pattern where the spokes are radially laced on the drive side and crossed on the opposite side.

This means the pedalling torque is transferred through the hub shell to the non-drive side spokes giving a much more balanced spoke tension (60/40 instead of 80/20 in some instances), which results in a more stable wheel, maintaining its lateral stiffness even when a high lateral stress is applied (heavy acceleration or climbing out of the saddle, for example)

ISM technology
Next up we patented our ISM technology (Inter Spoke Milling) which gave an extra 10% weight saving. And the weight is saved precisely where the rim suffers very little stress (in between each spoke), which maintains a very high strength level. Prototypes of this new wheel went on to win two Tour de France!

New for 2016: ISM4D
Year after year we have refined our Ksyrium technology and expanded its features (ISM3D, asymmetrical rims, double butted spokes, front carbon hubs…). So Ksyrium is constantly getting lighter, stiffer and stronger.

And this year we’ve done it again. For 2016 the Ksyrium SL becomes the Ksyrium Pro SL with a brand new rim, based on our new rim weight saving technology: ISM4D (Inter Spoke Milling 4 Dimensions).

With ISM4D, each part of the rim is precisely machined leaving just the material needed to guarantee the stiffness and strength of the wheel. The result is a superlight rim at just 370g that also saves you 4 watts thanks to its smoother aerodynamic shape. The total wheel weight remains at an impressively low 1395g.

Matching Yksion Pro tyres
The rim is matched with our Yksion Pro tyres that offer a supple 127 TPI casing, Kevlar beads, a well-balanced rubber compound that offers the best blend of grip and rolling resistance and a weight of only 190g in 23mm and 205g in 25mm.

Ksyrium Pro SL is available with 23mm or 25mm tyres.

Weight : 1395 grams (Pair without tyre)

Key technologies:


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


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


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


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.


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


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.


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.


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.


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


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.
