The Reserve 42|49 Turbulent Aero DT 180 Dicut Carbon Wheelset embodies the next evolution in real-world aerodynamic wheel design—engineered for all-day speed, comfort, and confidence. Developed and refined using Turbulent Aero technology, the 42|49 is purpose-built for everything from epic endurance rides to the world’s toughest races, including the Paris-Roubaix and Giro d’Italia. With a 42mm front and 49mm rear rim depth, this mixed profile optimizes stability in crosswinds while maintaining aerodynamic efficiency across a broad range of yaw angles. The result is a wheelset that’s fast on the flats, predictable in gusts, and responsive on climbs. Reserve’s semi-hooked rim design allows for use with tubeless or tube setups across a wide range of tire widths (29–40mm), and the 25.4mm/24.8mm internal widths provide a broad, stable platform for modern high-volume road and all-road tires. True to Reserve’s ethos, the 42|49 features no rider weight limits, no tire restrictions, and easily serviceable details such as external nipples and standard spokes—performance without the fuss.

Every aspect of the 42|49’s aerodynamic profile was shaped through an exhaustive process of Computational Fluid Dynamics (CFD) modeling and wind-tunnel validation. Unlike conventional aero testing, Reserve’s Turbulent Aero methodology replicates real-world air movement rather than sterile, laminar flow—allowing engineers to fine-tune rim shapes for predictable handling in variable wind conditions. The result is one of the most stable and efficient aerodynamic wheelsets ever created. To ensure this aerodynamic edge doesn’t come at the expense of durability, Reserve developed a proprietary composite layup process in its Santa Cruz carbon lab. There, each rim’s fiber orientation is optimized for precise stiffness-to-weight balance, and impact and spoke-pull testing protocols simulate thousands of real-world riding miles. This process ensures the 42|49 achieves class-leading strength and reliability while keeping weight impressively low—just 1331g for the DT 180 Dicut configuration.

Backed by Reserve’s industry-leading lifetime warranty with no-fault crash replacement, the 42|49 Turbulent Aero DT 180 Dicut Wheelset is designed to deliver performance you can trust day after day. The wheelset pairs seamlessly with DT Swiss 180, 240, or 350 hubs, all with Centerlock disc mounts and 12x100mm / 12x142mm thru-axle spacing. Offered with XDR and HG-EV freehub options, it’s ready to slot into any modern high-performance setup. With its cutting-edge aero development, composite mastery, and practical “ride hard, we’ve got you covered” approach, the Reserve 42|49 defines the new standard for all-day aero performance—fast, stable, and built for the real world.
