Featuring Fore technology with no rim tape and the UST Tubeless system, this rear wheel is the ultimate choice for demanding cyclists seeking everyday performance, speed, and comfort.

Mavic Ksyrium SL Disc rear wheel highlights

• Patented ISM4D machining: Removes excess material between the spoke holes, reducing rim weight to just 400 g and drastically lowering rotational inertia.
• Fore technology (tubeless, no rim tape): The rim’s upper bridge remains intact, increasing stiffness by 20% while saving 30 g of rim tape per wheel.
• Patented aerodynamic spokes: Exclusive elliptical-profile bladed spokes help save up to 5 watts of rolling resistance.
• Infinity hub & ID360 freehub: Instant power transfer (9° engagement) thanks to the Instant Drive 360 dual-pawl system and non-contact spoke lacing.
• UST Road Tubeless system: Easy, airtight tubeless setup provides more traction and comfort, along with greatly improved puncture resistance.
• QRM Auto bearings: Sealed cartridge bearings with automatic preload adjustment for smooth, durable rotation with no mechanical play.
