Light and rigid, remain among the best XC wheels

Mavic Crossmax SLR wheels are available in two versions, Disc and V-brake. Made in 2009 remain unchanged for next season. The rims are made of light alloy Maxtal, an aluminum alloy with enhanced mechanical properties that result in a better rigidity of 30% and greater fatigue resistance compared to a conventional alloy 6106. They are made with a technology called ISM3D, allowing a considerable reduction of the rims, which is the foundation on the sides. The rim have a weight of 380 grams and are compatible with tubeless tires. The rims are also asymmetric (both front and rear) for a more open camber stiffness in the presence of high stress. The width of the circle is 17 mm. The spokes are 24 front and rear, crossed by two in the front wheel and Isopulse scheme rear, which provides the spokes mounted in a radial on the freewheel and crossed by two into the opposite side. The spokes are exhausted with variable thickness and alloy. The hubs are anodized alloy. The nominal width is 100 mm for the front and 135 mm for the rear. The bearings supplied belong to the set of Mavic QRM +: ring sealed bearings, cartridge, removable and require no maintenance and are easy to replace. The freehub body is equipped with technology FTS-X, this improves the rigidity of the hub-freewheel. The front axle is made of aluminum, the rear aluminum and titanium. The front axle's axis of 15 mm and using the 9 mm reduction is compatible with traditional forks. The house says a weight of 690 grams for the front wheel and 830 grams for the rear wheel.

The road test

The Mavic Crossmax SLR Disc are well maintained and implemented. Excellent anodizing, machining and assembly of the hubs and impeccable. Excellent weight, if that is no longer a record, there is still at the top. The mounting of tires is no problem, as the sprocket and installation disks. In motion is clear from the low weight and high rigidity of these wheels. They are also sliding, thanks to the good bearings, although in this respect, there are slightly higher than competitors. The light weight and rigidity provide optimal acceleration and efficient transfer of power to the rear wheel. The lightness also speeds up the entry of the corners and allows for easier work of the suspension, reducing unsprung weight value. Excellent braking, thanks to the proper alignment of the discs. The increased rigidity may affect the comfort, appearance on a secondary pair of wheels for high-level competitions. Adopting tubeless tires and low inflation pressure, turn out, however, more than good as long-distance comfort. Reliability is beyond any shadow of doubt and tested at length in very difficult locations and on different bike showed no signs of slowing down, he in spoke tension, it into the correct camber or retreated to the rims. Are wheels of the true 360-degree because they go well anywhere. On fast tracks ensure optimal speed and acceleration due to their rigidity, uphill take advantage of low weight, which is still a positive aspect in the lens and guided paths. A pair of wheels of high-level, are slightly heavier than other models, but you benefit for a high build quality and reliability. They are perfect for the agonist, but also for the amateur who fully appreciate the performance. The price is around 699 Euro, commensurate with the weight and quality.
