AERODYNAMIC PROWESS

Wind tunnel tests show that the CADEX Aero 4-Spoke Disc WheelSystem’s combination of a 50mm front and 65mm rear rim profile surpasses the aero performance of competitor disc wheel combinations in headwinds, while achieving lower side force drag in crosswinds.

FULL POWER

With its optimized composite engineering, the CADEX Aero 4-Spoke Disc WheelSystem achieves best-in-class stiffness and stiffness-to-weight ratios in both transmission and lateral stiffness. Combined with innovative CADEX Low Friction R3-C40 hub technology, the result is unrivaled power transfer and efficiency.

AERO CONTROL

Featuring race-proven hookless technology and a wide 22.4mm inner rim width, the lab-tested combo of a 50mm front and 65mm rear affords maximum aero advantage and total control in crosswinds. Disc brakes further enhance confidence and power in all types of conditions.

Technologies

CADEX 1K Carbon Weave

A premium carbon fiber fabric with bundles of 1,000 filaments woven in two directions providing a smoother finish and lighter weight.

CADEX Ceramic Bearings

Durable, ultra-hard ceramic bearings further increase hub rolling efficiency with lower rolling resistance and 1.5x smoother action than steel bearings.

Hookless Rim Design

Provides the best flow transition from the tyre to the sidewall of the rim, resulting in reduced aerodynamic loss when compared to standard hook bead rims, and featuring a continuous carbon fibre structure enhancing overall durability.

CADEX Precision Reinforced Layup

CADEX precision reinforced layup places high tensile strength carbon fiber only where needed, creating a strong, stiff structure at minimal weight.

CADEX R3-C40 Aero Hub

Aero optimized hub features 3rd generation CADEX Low-Friction internals with CADEX ceramic bearings and 40-tooth ratchet engagement.
