Combining the performance attributes of Mavic's new UST Road Tubeless system and purpose-built disc-brake technology, the Mavic Ksyrium Pro UST 6-bolt Disc Wheelset is a versatile all-rounder for your most challenging road rides. The lightweight rims, engineered with Mavic's unique ISM 4D technology, are built wider with a 19mm internal width and 23mm external width. They are integrated with the new Yksion Pro UST tubeless tire to create a user-friendly tubeless system that makes it easy to install and remove tires. And the benefits of the Road Tubeless system are clear: lower rolling resistance and the smoother ride quality that comes with the ability to run lower tire pressure with a reduced risk of punctures. So you can ride faster, more comfortably, while expending less energy. Mavic's extensive experience designing mountain bike disc wheels informed the engineering process of these wheels. Unlike a wheel with rim brakes, braking torque is distributed through the hub, spokes and lower rim before it reaches the ground. The braking load is also higher on the front wheel since the center of gravity is transferred to the front of the bike when it's decelerating. Thus, the front wheel needs to be overbuilt with more spokes (24 instead of 18 or 20), and those spokes need to be crossed on each side of the wheel to make sure brake torque is evenly distributed.
The rear wheel also needs 24 spokes, but since the braking torque is generally lower, Mavic uses Isopulse lacing (radial lacing on the drive side) to maintain a better balance of the spoke tension, thus greater stability and stiffness. The rear wheel features the fast-engaging Drive 360 freewheel system. The freewheel system is compatible with Shimano/SRAM and can be converted to Campagnolo or SRAM XD with optional driver bodies. Pre-installed with a 10-speed spacer, removable for 11-speed. Additional end caps are available below.
