Mavic R-Sys SLR Endurance Road Wheelset

The R-Sys SLR was created for Gran Fondo racers and everyone who loves big mountain climbs. It’s the ultimate wheel for the KOM. It’s not only one of the few clincher wheelsets below the 1300g mark, but also the most laterally stiff, with proven strength and durability and superior braking performance.

It features Tracomp technology, which stands for Traction/Compression and combines extremely low weight with high lateral stiffness. This innovative design allows the spoke to work both in traction and compression. These spokes are both round and hollow (tubes) so they won’t buckle when compressed. They are clamped on both ends by a nipple that is bonded to the spoke and directly threaded into the rim on one end and into a ring inside the hub on the other.

• Superlight carbon spokes are used to save weight and bolster stiffness, since carbon fibres don’t stretch as much as steel or aluminium. The result is a wheel that is 30% stiffer laterally than any other wheel in its weight category. 
• Tracomp also dampens road vibration and adds vertical compliance so you can ride longer with more comfort. 
• Since this is a true mountain wheelset, Exalith has been added which improves stopping distance by 20% in wet or dry conditions. The ISM 4D rims are not only superlight (370g), but they also save a few watts in aerodynamics, helping you descend even faster. 
• ISM 4D works by strategically removing material from the rim for a smooth, rounded superlight profile. 
• The wheels are fitted with Yksion Pro tyres, which offer a perfect balance of grip, rolling resistance and a low weight of only 210g for a 25mm size. The supple 127 TPI casing tyres are front and rear specific for added control and rolling efficiency. The R-Sys SLR Wheel-Tyre System is available with 23 or 25mm tyres.
