Mavic Ksyrium Black DEMO - 2018

“Amazing ride quality.” That’s how riders often describe their experience with Ksyrium wheels. Now we’ve made this versatile wheel system even better by improving the component that matters most: the rim.
The box section rim extrusion and low spoke count produce a smooth and comfortable ride, and our patented ISM (Inter Spoke Milling) technology further reduces weight. Lighter weight means lower inertia, and that leads to easier climbing and faster acceleration.
The bladed spokes are radially laced on the front wheel for improved lateral stiffness. On the rear, we use our exclusive Isopulse lacing pattern (radial on the drive side, crossed two on the non-drive side) to balance the spoke tension. A wider driveside bracing angle creates higher lateral stiffness under heavy loads such as climbing or sprinting. The rims are paired with our proven QRM bearings and axle system, which minimizes friction and ensures high durability with no service needed.
