If you are excited for a wider, high end disc road wheel, Mavic enters the gravel racing market near the top, with the Ksyrium Pro Allroad Disc wheels. Of course, these aren't just for gravel roads, but for any rider who wants a wider, high performance disc road wheel. The 19mm internal rim width favors 28-42mm wide tires, so we can see these wheels being used effectively in cyclocross as well. Mavic's hub system on this Rear wheel gives you the flexibility to run standard QR's, or a 12mm thru-axle with easily changed (and provided) hub end caps. And it is a Ksyrium, with all the accumulated technology and Mavic engineering you trust and respect. Mavic enthusiasts will be highly interested in the new Instant Drive 360 freewheel system.

The Allroad system was designed to be light, stiff, and strong, while providing excellent handling, instant acceleration, and powerful braking. While Ksyrium wheels have been known to be vertically stiff, the larger tire volume and Iso-Pulse (2x non-drive, radial drive) spoke configuration will help to lend vertical compliance The hubs is more centered for dish and the crossing outer spokes are more accessible for replacement. Remember, this is still a high performance wheel. Mavic has taken the best of it's mountain and road technologies and developed a highly capable disc road wheelset.

The rear wheel features 24 Zicral aluminum bladed spokes, attached to the disc specific Ksyrium Allroad disc rim. ISM4-Dimension milling removes material in a patented concept that keeps the rim structure strong, but reduces rotating mass and, in conjunction with the wider rim width, improves overall aerodynamics. The 26mm section rim is a superlight, incredibly strong, Maxtal extruded structure that is joined using the arc welded and milled SUP joint. FORE drilling keeps the spokes and the nipples on the outer surface. That leaves the rim bed smooth and completely intact and creates the ultimate UST tubeless interface.

Mavic's disc road rear specific, machined aluminum hub employs the 2x/radial Iso-Pulse lacing, which balances the uneven forces and creates greater tension on the non-drive side radial spokes. This results in greater lateral stiffness at any wheel angle, and exceptional power transfer. The QRM sealed cartridge bearings feature double seals, are of very high quality and are ultra efficient, durable, and easy to replace. The disc interface is Center Lock, which gives you the simplest and most direct rotor mounting system, and can be used with CL rotors, or 6 Bolt style with an adapter.

Maic has made a huge, and welcome, departure from the FTSL freehub system. The new Instant Drive 360 system is a dual ratchet design with 9 degree engagement. This may remind you of a highly reliable system from another company. Engagement is much quicker and consistent than FTSL's pawl system, is less prone to wear and requires less service. On top of that, it is 45g lighter. We approve.

In keeping with Mavic's Wheel Tire System, the Kysrium Pro Allroad Disc rear wheel comes with an Allroad Yksion Powerlink 30mm rear specific tire that has been designed to deliver minimal rolling resistance and durability, but with solid grip and the extra puncture protection of a Kevlar breaker. The 120 tpi casing, dual-density tire runs a firmer compound in the center for lower rolling resistant and durability, and gets softer as it curves for better handling and increased traction. A constant center bead rolls fast, and a modified file-type tread rounds the edges.

Put it all together and you realize just how much technology Mavic has developed and engineered over time and how it can come together to produce a class-leading wheel. We expect the Ksyrium Pro Allroad Disc wheels to be well received and popular with riders who put performance first and have long experience with Ksyrium designs. And we fully expect every one of them to praise the Instant Drive 360 freewheel system.
