Oval CX

Brand

Colnago

Description

The Colnago Oval CX, introduced in the early 1980s, represents a significant advancement in aerodynamic bicycle design. Developed in collaboration with Columbus, this model features distinctive oval-shaped tubing aimed at reducing aerodynamic drag and enhancing frame stiffness.

Frame Design and Construction

The Oval CX is distinguished by several innovative design elements:

  • Oval-Shaped Tubing: The frame utilizes Columbus Oval CX tubing with an oval cross-section, increasing vertical stiffness and improving aerodynamic efficiency.

  • Specialized Lugs: To accommodate the unique tubing, the frame incorporates custom lugs, contributing to its distinctive appearance.

  • Internal Cable Routing: Both shift and rear brake cables are routed internally—the shift cables through the down tube and the rear brake cable through the top tube—resulting in a cleaner aesthetic and reduced air resistance.

  • Aerodynamic Fork: The CX fork features a flat side profile designed to minimize frontal drag, enhancing the bike's aerodynamic performance.

  • Reverse-Mounted Rear Brake: The rear brake is mounted inside the rear triangle, a design choice aimed at further reducing aerodynamic drag.

These features collectively contribute to the Oval CX's reputation as a pioneering aero road bike.

Notable Features

The Oval CX includes several distinctive characteristics:

  • Shift Lever Placement: Shift levers are mounted on top of the down tube, a unique positioning that complements the bike's aerodynamic design.

  • Cromovelato Finish: Some models feature a Cromovelato paint finish, achieved by chrome-plating the entire frame and applying a tinted color coat, resulting in a reflective, glossy appearance.

  • Absence of Chainstay Bridge: The design omits a chainstay bridge, a choice that aligns with the bike's streamlined aesthetic.

These elements highlight Colnago's commitment to both form and function in the Oval CX.

Legacy and Collectibility

Produced for a limited time, the Colnago Oval CX is now considered a collector's item, valued for its innovative design and rarity. Its unique features and historical significance make it a sought-after model among vintage bicycle enthusiasts.
