Mavic Ksyrium Pro Disc Wheel Set
The Mavic Ksyrium Pro Disc Wheel Set meets the unique demands of putting disc brakes on a road bike. As with all Ksyrium wheels, it can handle long, hard miles like no other, with the versatility to handle the most Epic All Weather Rides
The biggest difference between the two braking systems is that braking with discs displaces the brake forces from the rim to hub, moving them further away from the ground. To make its way from the hub to the ground, the braking torque is distributed through the hub, spokes and finally the lower rim. So the spoke dimensions and lacing pattern needs to be tuned accordingly. The braking load is higher on the front wheel since the center of gravity is transferred to the front of the wheel when the bike is decelerating. Thus, the front wheel needs to be overbuilt with more spokes (20 instead of 18) and those spokes need to be crossed on each side of the wheel to make sure the brake torque will be efficiently and evenly distributed. The lower part of the rim also undergoes higher stress than a rim brake wheel. This stress is about the equivalent of the pedalling torque so what the rear rim can withstand in traction, it can also stand when braking. The front rim however, needs to be redesigned and gets the same dimension as the rear rim, also benefitting from asymmetrical design as the disc creates asymmetry in the wheel dish.
The rims use unique ISM4D technology (Inter Spoke Milling 4 Dimensions) and makes sure the rim weight is kept at a minimum for better agility and reactions when speeding up or braking. By only using material where it’s needed for stiffness or durability, we can achieve extremely low weight without making compromises elsewhere. As a result the Ksyrium Pro Disk is just 1535g – allowing a great choice for any disc-brake-equipped road bike.
Matching Yksion Pro tyres make sure all this extra stopping power reaches the ground, the Ksyrium Pro Disc comes with Yksion Pro tyres in 25mm. They offer a supple 127 TPI casing, Kevlar beads, a well-balanced rubber compound that offers the best blend of grip and rolling resistance and a weight of only 190g in 23mm and 205g in 25mm.
