Mavic's 2019 Ksyrium Pro Carbon SL UST Wheelset is super light and fast, with UST Road Tubeless technology. By removing tubes from the equation, UST Road Tubeless technology eliminates friction, which in turn, reduces rolling resistance and increases speed. Plus, without a traditional tire and tube, these wheels run 40g lighter. UST Road Tubeless delivers smoother ride quality by allowing lower tire pressure and increased protection against punctures. These wheels are safer, too, thanks to iTgMax carbon technology, which provides substantial heat resistance, and a careful laser treatment that removes resin from the brake track, producing predictable performance in wet and dry conditions. The spokes are bladed and double butted, with 20 up front and 24 at the rear - light, stiff, and reliable. Equipped with the Drive 360 freewheel system, the hubs offer fast engagement, high axle stiffness, and durability.
The 2018 Ksyrium Pro Carbon SL UST Wheelset comes with a tire sealant syringe, Mavic tire sealant (rear wheel), tubeless rim tape, BR601 titanium quick releases, a multifunction adjustment wrench, carbon brake pads, a UST valve and accessories, and a user guide.
