Engineered for peak performance across all road conditions, the Mavic Cosmic SLR 45 Disc wheels are the most advanced carbon road wheels Mavic has ever produced. Built around a 45mm deep rim made from 100% carbon fiber with a UD² external layer, the SLR 45 delivers outstanding aerodynamic efficiency and lateral stiffness. The 23mm internal width enhances tire volume for better grip, comfort, and rolling resistance, while the Fore Carbon tapeless tubeless system ensures a clean, airtight seal with no need for rim tape. With front and rear wheels sold separately at just 676g and 806g respectively (1482g total), the SLR 45 is a race-ready option for riders seeking lightweight responsiveness and aerodynamic gains.

Mavic's aero expertise is fully realized in the SLR 45’s design, featuring elliptical steel spokes that reduce drag and increase crosswind stability. The reduced rim inertia allows for lightning-quick acceleration and an agile ride feel, ideal for breakaways, punchy climbs, or technical criteriums. The INFINITY hub platform ensures maximum power transfer and structural harmony, while the Instant Drive 360 freewheel system provides fast engagement and smooth drivetrain integration with Shimano HG road setups. The 2-cross lacing pattern on both wheels adds durability and ride compliance without sacrificing responsiveness.

Reliability meets race-ready engineering with Mavic’s QRM Auto sealed cartridge bearings, which require no preload adjustment and maintain smooth operation through varying conditions. The disc-specific build supports Center Lock rotors, and the included adapters offer compatibility with both thru-axles (12x100 front / 12x142 rear) and quick-release setups. Each wheel is delivered with a multifunction adjustment wrench, M6 spoke tool, and UST tubeless valves, ready for immediate setup. Whether you're targeting a road race podium or seeking a top-tier upgrade for fast training rides, the Cosmic SLR 45 Disc combines efficiency, agility, and innovation in one elite package.
