The Mavic R-Sys SLR Wheelset is a vital weapon in your mountain arsenal.

The Mavic R-Sys SLR is the lightest clincher wheelset available and now designed with a wider, deeper rim.

When creating the R-Sys, Mavic's goal was to provide gran fondo racers and all cyclists who love the mountains with the best possible wheel to achieve their climbing goals. They created a wheel that’s not only one of the few clincher wheelsets below the 1,300g mark, but also the most laterally stiff, with high endurance, strength and the greatest braking ability.


Full Tracomp technology - R-Sys SLR features the full Tracomp technology, front and rear, which is exceptionally good for both climbing and descending. 

Tracomp stands for Traction/Compression and combines extremely low weight with high lateral stiffness for precision and control when descending – and full power transfer when climbing out of the saddle.

So why does Tracomp make such a difference? Well a traditional wheel works with spokes that are likely to lose their tension under high lateral loads or weaken the wheel components when the tension gets too high. Tracomp, on the other hand, brings extra lateral stiffness in all conditions by allowing the spoke to work both in traction and compression. To achieve this, spokes needs to be:

- Round and hollow (tubes) so that they won’t buckle when compressed

- Clamped on both ends by a nipple that is bonded to the spoke and directly threaded into the rim’s Fore drilling and then into a ring inside the hub that locks the spoke head and prevents the spokes from travelling inside their slots

- Carbon to provide the desired weight saving and extra stiffness during the tension phase, as carbon fibers don’t stretch as much as steel or aluminum alloy

The result is a wheel that is 30% stiffer laterally than any other wheel in its weight category.

Low weight, low vibrations: The beauty of the Tracomp technology is that it also delivers two others benefits that every cyclist needs when going for an Alpine adventure: low weight thanks to the superlight carbon spokes, and road vibration dampening and vertical compliance for extra comfort, so you can ride longer, further and higher.

And it’s not just about the spokes... QRM SL bearing technology combines smooth and durable bearings in a very light package for extra performance.

Matching Yksion Pro tyres - This wheelset comes with Mavic's Yksion Pro tyres that offer a great balance of grip, rolling resistance and a low weight of only 205g in 25mm thanks to the supple 127 TPI casing, Kevlar beads and a well-balanced rubber compound.

The front wheel comes with the Griplink version that offers a specific tread pattern which helps evacuate water when cornering to increase confidence and speed in difficult conditions. It also offers very strong Kevlar puncture protection to improve safety.

The rear wheel comes with the Powerlink version, which sports a more supple nylon puncture protection instead of Kevlar to lower rolling resistance. To reduce rolling resistance and increase speed even further, the tread pattern is optimized to reduce the pressure on the ground, while improving water evacuation from the center to increase traction and efficiency in wet conditions.

ISM 4D - Inter Spoke Milling 4 Dimensions

An exclusive Mavic patented concept, ISM 4D not only significantly reduces weight and reduces inertia without compromising durability, but also improves aerodynamics due to its new rim shape.- Up to 50 grams lighter for faster climbing

- The lowest inertia for instant acceleration 

- A smooth aerodynamic rim shape to reduce drag

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.- Greater efficiency due to better transmission of efforts on the entire wheel

- Lightweight and strong hub design

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.

- Braking distance shortened by 18% in wet conditions, while keeping pads wear to normal level

- Exalith treatment penetrates the alloy to delay rim wear and maintain distinctive anthracite grey colour for thousands of kilometres

- New special black Mavic Exalith 2 brake pads to ensure quiet and high braking performance and longevity (delivered with the wheels)

Maxtal - Light and strong

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

QRM+ - Quality Mavic Bearings

These cartridge bearings are of course double sealed with C3 internal clearance, and toped with a micro-adjustability system.

-Tight tolerances for high rolling efficiency

- Quick adjustment according to performance goals: precision "free" adjustment for maximum fluidity, or perfect high precision setting for all-weather rides

Zicral - Light, stiff and strong

A specific aluminum alloy that provides spokes with higher stiffness-to-weight ratio while being stronger.

-Lighter spokes for easier climbing

- Stiffer spokes for better energy transmission

- Stronger spokes for increased durability

Griplink - 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.

Powerlink - 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.
