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.
