The Reserve 42|49 Turbulent Aero DT 240 Carbon Wheelset is engineered for riders who want the ultimate blend of speed, handling, and versatility. Sitting squarely between Reserve’s lightweight climbing and deep-section aero models, it balances agility and aerodynamic efficiency in one perfectly tuned package. With a 42 mm front and 49 mm rear rim, this wheelset delivers wind-tunnel-tested speed with stable, predictable control—ideal for long climbs, fast descents, and everything in between.

Reserve’s Turbulent Aero philosophy redefines aerodynamic design for the real world. Instead of chasing numbers in smooth, controlled airflow, the rims are shaped using advanced computational fluid dynamics and validated through on-road testing in natural, variable wind. The result is a profile that slices cleanly through gusts and yaw angles riders actually face on open roads. The 42 mm front rim minimizes steering feedback in crosswinds, while the deeper 49 mm rear maximizes forward thrust—creating a ride that feels fast, calm, and completely connected to the road.

Each rim is constructed from Reserve’s high-modulus carbon lay-up, precisely tuned to balance stiffness, strength, and low rotational mass. The internal width supports modern 28–32 mm tires, widening the tire’s footprint for improved cornering grip, lower rolling resistance, and enhanced comfort over long miles. A tubeless-ready, hookless rim profile simplifies setup, improves tire fit, and allows for lower pressures without compromising safety or performance. Lightweight yet robust, these rims hold true ride after ride, backed by Reserve’s lifetime warranty for complete confidence.

At the center, DT Swiss 240 hubs bring mechanical precision and quiet efficiency. Known for their reliability and minimal drag, the 240s feature the Ratchet EXP 36-tooth drive system, providing near-instantaneous engagement and long-term durability. Forged aluminum shells keep the weight low, while sealed cartridge bearings ensure smooth rotation through rain, dust, and everything the road can throw at you. The simple, tool-free design makes maintenance easy and fast—ideal for riders who demand professional-grade performance with everyday serviceability.

Buyers can select their preferred drivetrain interface—either SRAM XDR or Shimano HG—ensuring a clean, optimized setup without unnecessary weight. This dedicated-fit approach reduces friction, keeps alignment perfect, and offers flexibility should your build evolve. Installation is straightforward, and DT’s modular freehub design allows quick swaps down the line if needed. It’s an elegant, efficient system that aligns with the Reserve philosophy of purposeful simplicity.

Each wheel is laced with 24 Sapim CX Ray spokes in a two-cross pattern, chosen for their exceptional balance of strength, aerodynamics, and elasticity. The asymmetric spoke bed equalizes tension across both flanges, improving durability and maintaining long-term trueness. Every wheelset is hand-built and precision-checked by experienced technicians, ensuring perfect tension balance and flawless roundness from the first spin. It’s craftsmanship you can feel in every smooth, silent roll.

On the road, the 42|49 Turbulent Aero wheelset shines where versatility counts most. It accelerates quickly, responds instantly, and holds speed effortlessly across rolling terrain. The moderate rim depths make it a joy to handle in gusty crosswinds, while the aerodynamic shaping saves valuable watts at higher speeds. Climbers will appreciate the low inertia when the gradient turns skyward, while endurance riders will feel the efficiency and comfort that comes from refined design and advanced carbon damping. It’s a wheelset made for the unpredictable—the perfect match for modern road, all-road, and competitive training environments alike.

With 12×100 mm front and 12×142 mm rear thru-axles and a Centerlock rotor interface, the 42|49 is fully compatible with modern disc-brake framesets. The refined ride quality and mid-depth design make it equally suited to long training blocks, spirited weekend rides, and race-day intensity. Like every Reserve wheelset, it carries the brand’s lifetime guarantee, covering both manufacturing defects and impact damage—because performance shouldn’t come with compromise.

Ultimately, the Reserve 42|49 Turbulent Aero DT 240 Carbon Wheelset defines the all-round category. It’s quick enough for sprints, light enough for climbs, and stable enough for coastal crosswinds. It doesn’t force you to specialize; it lets you ride freely, confidently, and efficiently, no matter what the route demands. This is the wheelset for riders who want speed without anxiety, stiffness without harshness, and a connection to the road that feels as smooth as it is fast. It’s everything Reserve stands for—innovation, precision, and the joy of pure forward motion.
