Mavic's ultimate lightweight clincher wheelset now has a wider, deeper rim for . 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 choice to achieve their climbing goals. With the R-Sys SLR, they have 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.
This Wheel Tyre System features the full Traction/Compression (Tracomp) technology, front and rear. Tracomp combines extremely low weight with high lateral stiffness for precision and control when descending – and full power transfer when climbing out of the saddle. 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, the spokes need to be round and hollow (tubes) so that they won’t buckle when compressed. Also, they are 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.
Lastly, they are carbon which provides the desired weight saving and extra stiffness during the tension phase as the carbon fibres don’t stretch as much as steel or aluminium alloy. The result is a wheel that is 30% stiffer laterally than any other wheel in its weight category.
Tracomp technology also delivers two other benefits that every cyclist needs: low weight thanks to the superlight carbon spokes, and road vibration dampening and vertical compliance for extra comfort enabling a ride that is longer, further and higher. QRM SL bearing technology combines smooth and durable bearings in a very light package for extra performance. The 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. The Inter Spoke Milling 4 Dimensions (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.
The 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 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 centre to increase traction and efficiency in wet conditions.
