The Reserve 77|88 Turbulent Aero DT 240 Carbon Wheelset is the ultimate expression of aerodynamic speed. Born from Reserve’s most advanced aerodynamic research and refined through thousands of miles of testing, this wheelset is built for the rider who measures success in seconds saved. With a 77 mm front rim and an 88 mm rear, it delivers uncompromising efficiency in straight-line acceleration while maintaining the stability and control required for real-world racing conditions. Designed for triathletes, time trial specialists, and pure speed chasers, the 77|88 is a weaponized balance of power, precision, and predictability.

Reserve’s Turbulent Aero design process sets these wheels apart. Developed using high-fidelity computational fluid dynamics and verified under natural wind conditions, each rim shape is tuned to handle not only clean laminar flow but also the chaotic, shifting turbulence that defines outdoor racing. The result is exceptional aerodynamic efficiency that doesn’t vanish when the wind changes. The 77 mm front rim stabilizes steering input without dulling responsiveness, while the deeper 88 mm rear rim holds speed and delivers a powerful, locked-in feeling when you’re on the gas. Together, they form a wheelset that feels fast everywhere — not just in the tunnel.

Constructed from Reserve’s proprietary high-modulus carbon lay-up, the rims achieve remarkable stiffness-to-weight ratios and impact resistance. Each layer of carbon is positioned for optimal strength around spoke beds and high-stress zones, ensuring reliable performance under heavy load. The internal width supports 27–30 mm tires for reduced rolling resistance and improved aerodynamic transitions between tire and rim. The hookless, tubeless-ready design simplifies setup and enhances safety, letting riders run lower pressures for increased grip, comfort, and reduced fatigue on long courses. Despite the depth, the wheelset remains impressively light, making it as capable on technical descents as it is on flat, fast circuits.

At its core, DT Swiss 240 hubs deliver the smooth, precise, and low-drag performance that defines world-class wheelsets. The Ratchet EXP 36-tooth drive system provides near-instantaneous engagement, translating every watt into clean forward motion. Lightweight forged-aluminum shells house sealed cartridge bearings that spin with minimal friction, ensuring efficiency in all conditions — from rain-soaked road races to blistering triathlon transitions. Maintenance is effortless thanks to DT’s modular, tool-free design, so you can focus on speed, not servicing.

Buyers select their drivetrain interface — either SRAM XDR or Shimano HG — ensuring perfect integration without unnecessary hardware. The dedicated freehub approach keeps the build lean, light, and precisely matched to your groupset, while allowing easy conversion if you change drivetrains later. This clean modularity is the mechanical counterpart to the aerodynamic purity of the design: elegant, efficient, and built to last.

Each wheel is hand-built with 24 Sapim CX Ray spokes in a two-cross pattern, combining high tensile strength with aerodynamic thinness. The asymmetric spoke drilling equalizes tension across the wheel for stability and long-term trueness. Every wheelset is hand-tensioned, dished, and verified to Reserve’s exacting standards, ensuring consistency that you can feel in every rotation. The craftsmanship reflects the same obsessive precision found in the carbon shaping — a seamless fusion of performance and reliability.

On the road, the 77|88 Turbulent Aero wheelset delivers a sensation of unstoppable momentum. Once up to speed, it holds velocity with a silent efficiency that feels almost effortless. The deep profiles cut through headwinds and shrug off crosswinds with remarkable calm, giving you the confidence to stay aero and stay fast. Acceleration feels direct and immediate, while the refined damping of the carbon lay-up keeps feedback smooth and composed. Whether powering through an Ironman bike leg or chasing a personal record on the flats, these wheels transform raw power into pure velocity.

Engineered for disc brakes, the 77|88 uses Centerlock rotor interfaces and 12×100 mm / 12×142 mm thru-axles for maximum stiffness and precise brake alignment. The wide stance and balanced spoke geometry provide predictable handling under braking and cornering, ensuring that the aerodynamic gains never come at the expense of control. And like all Reserve wheels, it’s backed by a lifetime warranty covering manufacturing defects and impact damage, offering total peace of mind for the most demanding riders on the planet.

For racers, triathletes, and aerodynamic purists, the Reserve 77|88 Turbulent Aero DT 240 Carbon Wheelset represents the pinnacle of modern wheel design — where advanced engineering meets the intuitive satisfaction of effortless speed. It’s the wheelset that makes you feel faster the moment you roll out, not because of what the data says, but because the road suddenly feels shorter, smoother, and faster beneath you. When seconds matter, and confidence is everything, this is the wheel that leaves nothing to chance and nothing on the table.
