The Reserve 63 DT 370 Carbon Rear Wheel brings wind-tunnel refinement and long-haul reliability together in one fast, accessible package. With its deep 63 mm rim profile and DT Swiss’s proven 370 hub, it’s designed for riders who crave aerodynamic efficiency, confident stability, and easy serviceability. Whether sprinting for the line or cruising into a headwind, this wheel turns smooth power into sustained speed you can trust every ride.

The 63 mm rim is shaped using Reserve’s real-world aero development process — optimized through CFD modeling and outdoor validation to perform across the widest range of yaw angles. The deep section minimizes drag while maintaining stability in gusts and crosswinds. Reserve’s proprietary carbon lay-up keeps torsional stiffness high for efficient power transfer, while tuned vertical compliance smooths out vibration on long, rough roads. The 21 mm internal width supports 25–32 mm tires, forming a broad, stable contact patch that improves traction, reduces rolling resistance, and enhances comfort. Tubeless-ready and hookless by design, the rim simplifies setup and allows lower pressures for better control and speed.

At the hub, DT Swiss’s 370 delivers the hallmark precision and durability of Swiss engineering. Built from forged aluminum and fitted with the Ratchet LN drive system, it offers clean, positive engagement and low-maintenance performance for thousands of miles. The sealed cartridge bearings keep rotation smooth in all conditions, while optimized flange geometry ensures balanced spoke tension and responsive stiffness under load. Riders can choose between Shimano HG and SRAM XDR freehub bodies for seamless drivetrain compatibility — each providing crisp shifting and efficient power transfer no matter the setup.

Each wheel is hand-built with 24 Sapim Race or CX-Ray bladed spokes in a two-cross pattern, combining aerodynamic efficiency with tensile strength. The asymmetric spoke drilling balances tension between drive and non-drive sides, preserving alignment and long-term trueness even under heavy torque. Reserve’s meticulous building standards guarantee perfect dish and spoke balance straight from the truing stand. The result is a wheel that accelerates instantly, holds speed effortlessly, and feels calm when the wind starts to bite — the hallmark Reserve ride experience.

The Reserve 63 DT 370 Carbon Rear Wheel proves that deep-section speed doesn’t have to mean high-maintenance complexity. It’s built for racers, endurance riders, and everyday cyclists who demand reliable performance with a measurable aerodynamic edge. Light, fast, and rock-solid, it’s the wheel that carries Reserve’s DNA of efficiency, strength, and confidence into the deep-aero realm.
