Mavic Ksyrium Pro Carbon SL UST Disc Road Wheel Set

The Ksyrium line has always offered the unbeatable combination of light weight, high stiffness, comfort and reliability.Now we’ve added our UST Road Tubeless technology to make the Ksyrium Pro Carbon SL UST even faster. Eliminating the tube also eliminates friction, so you roll faster with greater efficiency. And now you can run lower tire pressures in the Yksion Pro UST Tubeless tires for increased comfort and a reduced risk of flats. As a bonus, the UST system including sealant weighs less than a traditional tube and tire system.This disc brake specific version benefits from an increased width to 21mm (internal). As the air volume increases, rolling resistance decreases and comfort is improved. The specific outer shape was defined according to the NACA requierement: 26mm external width for 32mm depth provide the best balance of low weight and rotational mass for easier faster climbing, and aerodynamics for fast downhills and valley transitions.The spokes are using our patented elliptical bladed shape for increased aerodynamics. Being double butted they are light and improves the ride quality. Using 24 spokes front rear creates high stiffness, low weight and long-term reliability.The Ksyrium Pro Carbon SL UST Disc also includes our new Instant Drive 360 freewheel system hubs for fast engagement, high axle stiffness and great durability. And if you need to service it, the tool-free design makes it simpler than ever.The front hub is convertible from 12mm thru-axle to quick release while the rear wheel comes with a 12x142 thru-axle and is convertible to quick release.The freewheel system is compatible with Shimano/SRAM and can be converted to Campagnolo or SRAM XD with optional driver bodies.Key Features:Superlight optimized for disc brakes for instant acceleration and fast climbing.,Super low weight 32mm NACA rim profile.,21mm internal width, optimized for 28mm tires to deliver the best ride quality.,32mm aero optimized only possible when removing the constraint of the brake track.,New slick 12mm only front hub.,Super high efficiency optimized for disc brakes.,Low friction durable bearings with automatic play adjustment.,Reactive Instant Drive 360 freewheel system.,Optimized spoke lacing.,Roll faster and smoother with a reduced risk of punctures.,Specific rim width for disc brake bikes improves ride quality.,Mavic Road UST increases rolling efficiency and reduces chances of flats.,Rim and tire are made for each other: easy to install and repair..CompatibilityFront axle: 12mm thru axle, easily convertible to quick release with included adapters.
