When creating the R-Sys, our goal was to provide gran fondo racers and all cyclists who love the mountains with the best possible wheel choice to achieve their climbing goals.
With the R-Sys SLR, we created a wheel that’s not only one of the few clincher wheelsets below the 1300g 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, which stands for Traction/Compression, 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.
Exalith – for downhill:
R-Sys SLR is a true mountain wheelset that recognizes once you’ve reached the top, you’ll have to go back down.
For that, Exalith is a great compliment to the R-Sys SLR features. Exalith shortens stopping distance by 20%, wet or dry, and provides powerful and easy to modulate braking to give you total confidence downhill.
ISM4D: save weight, save Watts:
The ISM4D rims are not only superlight, at just 370g, but they also save a few watts in aerodynamics, helping you descend even faster. ISM4D works by removing any material from the rim that is not needed for durability or stiffness to create a smooth rounded rim profile.
Matching Yksion Pro tyres:
The wheel comes with our 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 our 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.

- Hold the road in any situation: light and supple high density casing
- Reduced risk of flats: strong Kevlar anti-puncture breaker
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.
- Superior energy transfer, reduced rolling resistance and safe grip thanks to optimized tread pattern
- Improved drive: light and supple high density casing
- Higher durability and reduced risk of flats: nylon anti-puncture breaker
Light & stiff traction compression. Extremely light Tracomp carbon fibre spokes works in traction and compression to provide a very high stiffness level in any circumstances.
- Under normal loads, wheel deflection is limited by the very high traction resistance of carbon fibres
- Under greater loads, where a normal wheel would flex more because of one of its spoke loosening, Tracomp spokes enter into compression and keep supporting the rim, preventing any further wheel deflection
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
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.
- Rim is 4 times more resistant to fatigue stress
- 20% increase in the rim rigidity to maximize power transfer
Qualité de Roulements Mavic Super Light The super light bearings are designed having in mind the QRM strict specifications. The matching hub axles are machined within extremely narrow tolerances, then one by one adjusted with very high precision when assembled.
